Book summary “After the trade is made”: summary

Introduction

You face immense operational complexity when handling securities transactions in modern financial markets. A single trade error or settlement failure can trigger severe financial losses and regulatory penalties. You must master the intricate mechanics of clearing, settling, and financing trades to protect your firm and your clients.

Mastering the mechanics of front, middle, and back office operations is essential to clear, settle, and finance securities transactions accurately and safely.

David M. Weiss provides a comprehensive guide to broker/dealer operations in After the Trade Is Made. You will learn how the industry functions from order execution through final settlement, custody, and accounting. The book traces the complete lifecycle of a trade across diverse asset classes and regulatory frameworks.

You will find answers to several crucial operational questions as you read:

• How do broker/dealers obtain licenses and structure their internal operations?
• What mechanisms govern order execution, figuration, and continuous net settlement?
• How do margin accounts, stock borrows, and repos finance securities positions?
• What rules dictate the segregation, custody, and institutional delivery of assets?
• How do firms maintain accurate stock records and satisfy regulatory reporting mandates?

1. Broker/Dealer Operations and Market Structure

To legally operate as a broker/dealer in the United States, an entity must obtain a specific license from the SEC by completing a detailed application and designating a self-regulatory organization.

Securing a federal license requires precise preparation and administrative filings.

The licensing process begins with a 36-page application submitted to the Securities and Exchange Commission. The SEC reviews the application, and any future business changes require amending the license.

To complete this process successfully, you must address several specific operational requirements:

• complete a thirty-six-page application to become a broker/dealer;
• specify who the principals, CEO, and CFO will be;
• indicate if conducting business directly with the public;
• state whether the entity will be a market maker and of what products;
• determine if the entity will clear its own trades or use a correspondent-clearing firm;
• specify if checks and securities will be accepted from and issued to clients;
• provide the tax ID number and main office location;
• designate the self-regulatory organization.

International financial leaders established the G30 recommendations in the mid-1980s to harmonize cross-border transaction clearing and settlement methods. These guidelines set standards such as T + 1 for comparison effected and T + 3 for settlement of corporate issues.

Component Parts of a Broker/Dealer

A typical heavily automated broker/dealer is divided into three primary functional components: the front office, middle office, and back office.

The front office focuses on revenue generation through retail and institutional sales, trading, investment banking, M&A, and research. The middle office handles order control, verifying client and security databases, order matching, coding, figuration, and trade verification. The back office manages everything from the executed order to final settlement.

A fictitious firm named Stone, Forrest & Rivers illustrates the application of client master databases, security master databases, and order match systems.

The Markets

Securities markets operate primarily either as agency markets where brokers execute public orders without financial interest or as principal dealer markets where market makers trade against their own inventory.

Real estate and insurance brokers act as agents charging commissions, whereas new car and appliance dealers own products and add a markup. Security markets are two-sided markets defined by a quote consisting of a bid and an offer, along with the corresponding size indicating the number of shares.

Shares quoted as 26.50-.70, 40 x 80 mean a bid price of $26.50 for 4,000 shares and an offer price of $26.70 for 8,000 shares.

Industry Regulators

The brokerage industry is subject to multi-layered regulation enforced by the federal government, state authorities, and industry self-regulatory organizations.

The Securities and Exchange Commission at its headquarters located at 450 Fifth Street, NW, Washington, DC promulgates rules such as Regulation T and net capital requirements. State regulators oversee intra-state business, requiring broker/dealer licensing, representative registration, and blue skying of unlisted securities. Self-Regulatory Organizations like the NYSE and NASD enforce federal and industry rules, conduct periodic audits, and oversee trading operations.

To remain compliant during daily operations, you must follow specific regulatory steps:

• ensure the broker/dealer and stockbroker are licensed and registered within the client's home state;
• verify that unlisted securities are approved for sale via blue skying before offering them to clients.

2. Corporate, Municipal, and Government Securities

Financial markets utilize a diverse array of instruments, ranging from common stock and corporate bonds to municipal obligations and U.S. Treasuries, each governed by unique pricing and yield mechanics.

Corporate Securities

Common stock represents primary corporate ownership, generally entitling shareholders to one vote per share and rights to dividends and capital growth. Corporations issue common stock to raise public capital through negotiated underwritings managed by investment bankers. Shares trade over the counter or on exchanges as round lots or odd lots, with ownership tracked via transfer agents and registrars.

RAM Corporation has 10,000,000 shares of common stock outstanding, meaning an owner of 1,000 shares owns 1/10,000 of the corporation. A normal trading unit is known as a round lot of 100 shares.

Preferred stock provides priority claims on assets and dividends ahead of common stockholders, usually operating as a fixed-income instrument with specialized optional features. Preferred shares pay stipulated dividends expressed as a dollar sum or percentage of par value. They may include features like cumulative, callable, convertible, participating, or adjustable rates to balance issuer needs with investor demand.

A 4% preferred stock with a $100 par value is expected to pay $4 per share per year.

Rights and warrants grant holders the privilege to acquire new common stock below current market prices, serving as short-term subscription privileges or long-term sweeteners. Subscription rights are short-term privileges offered to existing shareholders under preemptive rights clauses. Warrants are longer-term options issued alongside other securities as units to lower overall borrowing costs.

Angelic Star Rockets, Inc. issues 5,000,000 rights where a stockholder must submit five rights and $60 to subscribe to one new share when the stock trades at $65.

To manage these assets, you must calculate valuations correctly:

• calculate the theoretical value of a right by dividing the difference between the market price and subscription price by the number of rights required for subscription.

Debt Instruments

Corporate bonds represent long-term debt obligations requiring fixed interest payments and principal repayment, with prices fluctuating inversely to market interest rates. Bond yields and prices move inversely; when market interest rates rise, outstanding bond prices fall, causing their yields to rise. Trading prices are expressed as a percentage of par value, and buyers must pay accrued interest calculated on a 360-day basis.

An 8% bond pays $80 per year per $1,000 of face value, yielding 8% when traded at par, or 8.89% when traded at a discount of $900. Corporate and municipal bond interest uses a 360-day annual basis divided into 180-day half-year interest periods.

You apply specific formulas when handling fixed income:

• calculate current yield by dividing the annual interest payment by the market value;
• calculate accrued interest by multiplying the face amount by the interest rate and the number of days, divided by 360.

Commercial paper is an unsecured short-term corporate debt instrument issued directly or through dealers to cover immediate financing needs. Commercial paper maturities are short, rarely exceeding 270 days, and transactions settle on the same day using Fedwire funds. Dealers finance unsold paper through collateralized loans or repurchase agreements. Maturities are typically 30, 60, 90, and seldom more than 270 days, with standard trading lots of $1,000,000 and possible minimum denominations of $25,000.

Municipal bonds are debt securities issued by state and local governments whose interest is generally exempt from federal income taxes and quoted on a yield-to-maturity basis. Because municipal bonds are issued in serial form and traded infrequently, they are quoted using basis pricing rather than dollar prices. Syndicate managers coordinate competitive underwritings to secure the best terms for taxpayers.

Investor Rick Atee in the 30% tax bracket receives a better net return from a 5% tax-free municipal bond ($50) than from a taxable 6.5% corporate bond yielding $45.50 after taxes. A sample 10-year bond present value calculation uses a 7% coupon rate.

You handle municipal discounts through specific accounting steps:

• amortize bond discounts or premiums by dividing the total difference between purchase price and face value by the number of years to maturity.

U.S. Treasury instruments are direct obligations of the federal government issued through Dutch auctions to finance government operations safely. Treasury bills are short-term discounted instruments up to one year, notes cover intermediate ranges from one to 10 years, and bonds cover 10 to 20 years. The Federal Reserve uses a Dutch auction structure where all accepted bids are filled at a single clearing price.

Minnie Sota purchases a 90-day Treasury bill with a $100,000 face amount discounted at 4%, paying $99,000 and earning an effective return of 4.04%. Treasury bonds and notes accrue interest using an actual-day basis of 365 or 366 days.

Mortgage-backed securities securitize pools of mortgage loans, passing through monthly principal and interest payments or redirecting cash flows into structured tranches. Mortgage bankers assemble loan pools that obtain government backing through agencies like GNMA, issuing modified passthroughs or collateralized mortgage obligations. Prepayments by homeowners affect the longevity and pricing of these instruments.

Abode Mortgage sells $5 million worth of 6% mortgages retiring in 30 years to a dealer using a TBA forward contract. This sector began in 1970, and the Bond Market Association sets an over- or underdelivery tolerance level of .01% per million.

You evaluate these pools using specialized resources:

• determine the current principal of a mortgage pool by multiplying its original value by the factor obtained from Factor Tables.

Derivatives and Alternatives

Options and futures are derivative contracts providing rights or obligations to buy or sell underlying assets at set prices, serving as tools for hedging, speculation, and income generation. Options give holders the privilege to buy calls or sell puts underlying assets by paying a premium to a writer. Futures are standardized exchange-traded contracts requiring daily margin adjustments and variation settlements.

An owner of a ZAP Apr 50 call has the privilege of buying 100 shares of ZAP common stock at $50 per share until expiration. Listed options opened with the 1973 opening of the Chicago Board Option Exchange, using 100 shares as the standard number of underlying shares for an equity option contract.

Swaps and foreign exchange transactions allow institutions and traders to manage currency risks and exchange cash flows to achieve optimal borrowing terms. Interest rate swaps exchange fixed-rate obligations for floating-rate terms based on a notional principal. Currency swaps allow entities to borrow in foreign jurisdictions using favorable local credit ratings while eliminating exchange rate exposure.

Marquis Corp. and Lincoln Mortgage execute an interest rate swap to match their respective short-term and long-term revenue and expense streams. Global foreign exchange markets trade more than 100 currencies daily.

3. Order Management and Execution Mechanics

Executing customer orders requires precise navigation of exchange auction principles, over-the-counter dealer markets, and specialized order constraints.

Order Types and Constraints

Brokerage operations execute customer orders either on an agency basis via an exchange floor or on a principal basis through over-the-counter market makers. In an agency transaction, you pay a commission while a broker executes your order against a third party. In a principal transaction, a market maker uses inventory to fill your order on a markup basis.

Ted Baer's purchase of Electra Corp. on the NYSE was executed on an agency basis with a commission added, while Ali Waih's purchase of Ultra Corp. via NASDAQ was executed on a principal basis by SF&R's trading desk with a markup.

Market quotes combine the highest bid and lowest offer, accompanied by the size representing available market depth in round lots of 100 shares. Orders can be constrained by time, such as day orders or good-till-canceled orders. When a stock goes ex-dividend, marketplaces automatically adjust pending limit prices to prevent unintended executions.

RAM closes at 45 dollars per share on the day before going ex-dividend by 0.20 dollars, prompting the marketplace to adjust the closing price to 44.80 dollars and reduce a buy limit order from 44.90 dollars to 44.70 dollars.

Exchange and OTC Execution

Short sales involve selling borrowed stock to profit from falling prices, historically requiring execution on an uptick or zero uptick. Stop orders act as memorandum orders that convert into market or limit orders once a specific trigger price is reached. Traders also use specialized multi-leg options strategies:

• Spread orders to lower net investment cost by simultaneously buying and selling related options;
• Straddle orders to profit from high volatility by buying a put and call with identical terms;
• Combination orders using different series designations.

Floor brokers and specialists on the New York Stock Exchange execute orders according to strict rules of priority, precedence, and parity. NASDAQ operates as a negotiated dealer market where competing market makers commit capital and utilize automated routing systems like the Small Order Execution System for small orders.

William Bord makes a market in Ultra Corp., maintaining an inventory of 50,000 shares while capturing the spread between his bid of 26.40 dollars and offer of 26.80 dollars.

The Debt Market

Debt instruments trade based on present value cash flow calculations. Corporate bonds trade at dollar prices in bullet form, while municipal bonds trade on a yield-to-maturity basis in serial form.

To compute municipal bond yields, you follow these steps:

• Subtract the lower of market price or maturity value from the larger value.
• Amortize the resulting difference over the life of the bond.
• Add the annual adjustment to the annual interest payment if at a discount, or subtract it if at a premium.
• Divide the sum of cost and maturity value by two to find the average value, then compute the yield to maturity.

4. The Order Management System and Trade Figuration

Automated order management systems validate incoming instructions against master databases, code transactions, compute net money through figuration, and clear trades via continuous net settlement.

Database Validations

You rely on the order management system to verify incoming orders before routing them to the marketplace via DOT, SOES, CAES, ACES, or ECNs. You prevent costly errors and ensure regulatory compliance by following these operational steps:

• Verify security symbol accuracy in the security master database.
• Check limit prices against the last sale of the security.
• Cross-reference the customer master database for correct account number, name, and registered rep number.
• Verify customer trading approvals for the specific product.
• Forward approved orders to the point of execution and place them in an order pending file.

Stone, Forrest & Rivers uses its order management system to check orders before routing them to marketplaces.

Trade Figuration and Comparison

Trade figuration computes first money, commissions, regulatory fees, and accrued interest to determine the final net money settlement for each transaction. You execute figuration using specific baseline instructions:

• Calculate first money by multiplying security quantity by the execution price.
• Add commissions and service fees to first money for buy trades, and subtract them for sell trades.
• Apply the federal regulatory fee of .0039 for every $100 of first money on exchange and NASDAQ sell transactions.
• Compute accrued interest for debt instruments using the appropriate day-count methodology from the security master database.

A client selling 100 shares of Bonneville Inc. at $42 on the AMEX incurs an $84 commission and a $.17 regulatory fee, yielding net proceeds of $4,115.87. Clearing corporations compare trade details between counterparties and use continuous net settlement to minimize interfirm deliveries and adjust market values daily. You process these matches through structured clearing steps:

• Submit matched trade data to the clearing corporation through automated comparison systems like ACT or DOT.
• Review contract sheets for compared, uncompared, or advisory status.
• Resolve uncompared trades and advisories using acceptance notices or question trades.
• Execute netting calculations using the Clearing Cash Adjustment to neutralize execution price differences against a common settlement price.

Options Processing

Listed options trade on next-day settlement and require strict position coding to track opening and closing actions against the Option Clearing Corporation. You manage option positions by observing standardized workflows:

• Designate the position effect on the order ticket as buy open, buy close, sell open, or sell close.
• Verify trade comparison reports on the evening of trade date.
• Reconcile daily client and proprietary position reports from the Option Clearing Corporation.
• Apply exercise by exchange rules for automatic exercise of in-the-money options at expiration.

A client holding 30 calls and 15 writer contracts adjusts positions based on daily activity, incorporating buy opens, sell closes, exercises, and assignments to arrive at closing totals.

5. Margin Accounts and Financing Mechanics

Customers can acquire securities either through a cash account where they pay in full or through a margin account where the brokerage firm finances part of the purchase. In a cash purchase, full payment must be made by the settlement date and no later than the second business day thereafter. In a margin purchase, you pay a portion of the price while the firm finances the rest by borrowing from a bank, lending the stock to another user, or settling someone else's transaction, charging you interest on the debit balance.

Della Kattessin buys 100 shares of ZAP at $42 for a $4,200 market value in a cash account, paying in full with zero debit balance. Jay Walker buys 100 shares of RAM at $50 in a margin account, paying the 50% Regulation T minimum of $2,500 while the firm lends the remaining $2,500 debit balance.

Regulation T dictates initial customer obligations set by the Federal Reserve, while SRO rules like NYSE Rule 431 establish ongoing minimum maintenance requirements.

Regulation T sets the initial margin rate and requires a minimum equity of $2,000 before a firm can lend money. Maintenance rules dictate that account equity cannot fall below 25% of the market value, or equivalently, the equity cannot become less than one-third of the debit balance; otherwise, a maintenance call for additional collateral is issued.

Phil O'Dendrin purchases 200 shares of ROCO at $60 for $12,000 with a 50% margin requirement ($6,000 equity, $6,000 debit balance). When ROCO falls to $20, market value drops to $4,000, creating an unsecured debt balance and a maintenance call.

Margin Rules and Buying Power

When the market value of marginable securities increases, the excess equity over Reg T requirements is booked to the Special Memorandum Account (SMA). You can use SMA balances to withdraw funds or purchase additional securities without depositing new cash, using the rule that dividing excess by the margin rate yields the maximum purchase power.

Sara Toga buys 100 shares of DUD at $50, depositing $2,500 and borrowing $2,500. When DUD rises to $100 per share, her equity reaches $7,500, creating $2,500 of Reg T excess available in her SMA.

An account is restricted when its debit balance exceeds the current loan value but equity remains above the 25% minimum maintenance level. Restricted accounts do not trigger maintenance calls, and when you purchase additional stock, margin is required only for the new purchase rather than bringing the entire account up to standard. When securities are sold from a restricted account, you can withdraw 50% of the sale proceeds or the recomputed excess, whichever is greater.

Sandra Beech has a restricted account with $18,000 market value, $9,000 equity, and $9,000 debit balance. When she sells MAW at $30 per share, she can withdraw 50% of the proceeds ($1,500) or use it to purchase up to $3,000 in common stock.

Day Trading and Derivatives Margin

Day trading involves buying and selling securities within the same day without holding overnight positions, and it is strictly governed by special maintenance excess and pattern day trader rules. Day trading is illegal in cash accounts due to free-riding rules. In margin accounts, occasional day traders can use up to four times their maintenance excess, while pattern day traders can transact up to two times their maintenance excess during the day without depositing extra funds.

Clifford Hainga has $50,000 market value and $25,000 maintenance excess, allowing him to use four times that amount ($50,000) to day trade. Justin Tyme, a pattern day trader with $5,000 maintenance excess, can buy up to $10,000 worth of stock during the day.

When managing day trading activities, follow these steps:

• Pair off transactions timewise during the day to determine the largest amount of capital in use at one time.
• Verify that if limits are exceeded, 50% of the overage is deposited.
• Ensure profits are kept or withdrawn and losses are covered 100% at the end of the day.

Option margin requirements protect brokerage firms against real or perceived risks in uncovered options, spreads, straddles, and combos. Covered options involve no firm risk and require no margin, whereas uncovered equity options require a calculation of 20% of the underlying value plus the premium minus out-of-the-money amounts, with a minimum of 10% of the underlying plus premium. Spreads, straddles, and combos apply specific formulas comparing strike price differences and uncovered requirements.

Account 4CG002731 sells 10 uncovered calls of POW Apr 60 at 2 when POW is at $59, requiring a margin calculation where the higher amount of $12,800 is applied as the requirement.

Future margins are performance bonds based on a percentage of the underlying contract value and are adjusted daily through marking to the market and variation margin. Futures require standard margin maintained between 3% and 5% of the contract value, or up to 10% for index futures. Daily price fluctuations require marking to the market, transferring variation margin profits or losses between accounts, while Standard Portfolio Analysis of Risk (SPAN) margin uses preset algorithms to compute portfolio risk across futures and options.

Nathan Lee buys a 6-month gold contract on COMEX at $350 per ounce, depositing $1,750 standard margin. When gold closes at $350.50, Nat's account is credited with $50 variation margin.

Position Financing

Bank loans used to finance proprietary and margin positions require pledging nonsegregated securities subject to a bank haircut percentage.

Banks typically lend seventy cents on every dollar of market value for equity collateral, leaving a thirty percent haircut. The precise haircut can vary based on security volatility and financial stability, and interest is charged at the published broker's call rate.

Stock loans and borrows allow broker/dealers to reduce financing expenses by substituting high-interest bank loans with negotiated stock loans where cash collateral earns lower interest rates. When an institution needs shares to clean up fails or complete deliveries, it borrows them from a lender like SF&R, providing cash collateral. The lender pays you interest at a rate lower than the bank broker's call rate, creating a mutually beneficial cost reduction.

Third-party repurchase agreements involve a neutral financial institution that holds securities and cash in separate accounts until all transaction terms are verified, minimizing processing risk. Unlike physical repos which involve high custodian movement fees and segregated repos which carry insolvency risks for the lender, third-party repos use a neutral bank to ensure correct delivery of collateral before releasing funds.

SF&R enters into a repo with The Loster Motor Corporation, utilizing First Continental Bank as a neutral third party to hold securities and cash in dedicated accounts until settlement conditions match.

A matched book operation allows a broker/dealer to act as an intermediary, borrowing funds from low-cost lenders and lending them at a higher rate to smaller firms needing repo financing. The intermediary captures a small interest rate spread across large transaction volumes, earning risk-free profit while helping smaller broker/dealers simplify loan processing and avoid multiple bank negotiations.

SF&R borrows $100,000,000 from a money source at 3 percent and lends it to Brock, Holly, Robb and Company (BHR) at 3.25 percent. SF&R earns $684.93 per day while BHR saves $5,479.45 daily compared to higher broker call rates.

6. Segregation, Custody, and Institutional Settlement

Broker/dealers must maintain strict possession or control of fully paid customer securities through segregation rules while executing institutional deliveries and mutual fund settlements electronically.

Segregation Controls

Under Federal Reserve Regulation T, you must maintain possession or control of clients' fully paid-for securities. You can only use up to 140 percent of a margin account debit balance in margin stock to finance loans. Customer securities are pooled per account, and the calculation uses updated settlement and fail items. Violating segregation rules is a federal offense punishable by imprisonment, applying to retail, institutional, and correspondent broker/dealer clients.

Active segregation allows a broker/dealer to dynamically switch locked-up securities with free securities as long as the total dollar value remains equal and the segregation requirement is satisfied. Operations staff can release a security from segregation to fulfill a delivery or loan while pulling back another free security from a bank loan pledge to lock it up in segregation.

Client Stanley Tahl has 100 shares of ZAP locked up in segregation and 100 shares of RAM free on bank loan. When another broker/dealer requests to borrow ZAP, SF&R releases ZAP from segregation for delivery and locks up RAM into segregation from the bank loan pledge.

• Identify client accounts with securities locked up in seg and other securities available for loan.
• Verify that the substitute securities are trading at the same price and satisfy the seg requirement.
• Instruct DTC to release the needed security from seg for delivery or loan.
• Pull back the alternative security from the pledge account and lock it up in seg.

The needs analysis report prioritizes delivery needs based on cost and market exposure to prevent expensive overnight financing of incomplete large-scale institutional trades. When large transactions cannot be fully settled on the settlement date, you must borrow funds to pay delivering counterparties, generating unrecoverable daily interest expenses.

Reelibigg Trust Company purchased 100,000 shares of PIP at $60 per share for a total of $6,000,000. If SF&R accumulates only half the shares and must finance the $3,000,000 position overnight at a 6 percent interest rate, it incurs a daily unrecoverable interest expense of $493.

Institutional Settlement

Institutional trades settle electronically on a delivery-versus-payment basis through automated platforms and central depositories, eliminating the physical movement of stock certificates.

Under Rule 387 of the New York Stock Exchange, custodian banks representing institutions must be depository members. Trades are affirmed electronically, and securities are exchanged simultaneously with cash via bookkeeping entries on settlement date.

Major Insurance Company buys 500,000 shares of RAM at $60 per share using Brooklyn Bank & Trust Company as its custodian. SF&R delivers securities electronically through DTC, and the custodian bank releases client funds upon receipt.

• Send trade notification to the institutional client on trade date.
• The institution or its designee affirms or DKs the trade by trade date plus 1.
• Resolve any DK responses immediately with the stockbroker to correct account numbers or processing errors.
• Deliver securities electronically through DTC to the custodian bank on settlement date.
• Release client funds to the broker/dealer upon receipt of securities by the custodian bank.

Custodial Services

NSCC's FundServ acts as a centralized electronic conduit that streamlines mutual fund data transmission, order execution, and net daily cash settlement among financial institutions. Instead of separate bilateral communications between institutions and thousands of funds, FundServ processes buy, sell, and exchange orders, netting cash transactions into a single daily transfer.

The Automated Customer Account Transfer System processes the transfer of client accounts between broker/dealer firms electronically. Woodrow Oaks transfers his account from Knune & Knight to Stone, Forrest & Rivers because he moved to a new state.

• Woody can transfer his entire account to Stone, Forrest & Rivers.
• He can have his old firm liquidate his position and send a check to Stone, Forrest & Rivers.
• He can do a partial delivery, keeping some of the securities and/or money at the old firm.

7. Accounting, Stock Records, and Regulatory Reporting

Brokerage operations rely on the dual pillars of the stock record and the general ledger to maintain balance accuracy, resolve breaks, comply with net capital rules, and fulfill regulatory reporting mandates.

The Accounting Process

Brokerage accounting principles dictate that the money side of a transaction drives the security entry, connecting debits and credits across assets, liabilities, revenue, and expenses. Every accounting entry has equal offsetting debits and credits. Asset accounts have debit balances, liability and revenue accounts have credit balances, and cash movements govern whether a position is a receivable or payable.

Al Luminum buys 100 shares of ZAP at $47 with a $70 commission, resulting in a $4,770 total cost booked via accounts receivable and liability.

Stock Records and Breaks

The activity stock record reflects all position movements on a particular day, whereas the summary stock record serves as a snapshot of all active accounts and positions for which the firm is responsible, used for corporate actions, dividends, and proxies. Location accounts track where securities are physically or electronically stored, while short sales require specific borrow offsets.

Stock record departments monitor daily records for breaks where debits and credits do not match, as well as illogical positions or movements that represent operational errors. Stone, Forrest & Rivers uses the date as the first four digits followed by five nines, such as 042199999, to identify break accounts occurring on April 21.

Regulatory Compliance and Reports

Under SEC Regulation T, brokerage firms must lock up specific portions of client securities in cash and margin accounts to maintain possession or control at all times. SEC Rule 15c3-1 establishes net capital and aggregate indebtedness requirements to measure the financial strength and liquidity of broker-dealers.

• FOCUS Part I is filed monthly by the 10th business day.
• FOCUS Part II is filed quarterly by the 17th business day for firms that carry customer accounts.
• FOCUS Part IIA is filed quarterly by firms that do not carry customer accounts.
