Margin, Prime Brokerage and Stock Loan
This topic covers margin account operations, debit balances, margin calls, collateral, rehypothecation concepts, prime brokerage, stock loan, stock borrow, and locate processes.
How to study for Series 99
Treat each Series 99 item as an operations control workflow: verify authority, process accurately, reconcile breaks, preserve records, and escalate risk.
Core concepts
Concept 1
Margin, Prime Brokerage and Stock Loan questions test whether an operations professional can identify the correct operational control, processing step, record, or escalation path.
Exam cue: Identify whether the scenario involves account maintenance, money movement, settlement, processing, records, controls, or professional conduct.
Concept 2
The best Series 99 answer usually protects accurate account records, timely processing, reconciliation, supervision, customer protection, and regulatory reporting.
Exam cue: Match the answer to the operational evidence: authorization, documentation, comparison, reconciliation, reporting, supervision, or escalation.
Concept 3
Eliminate answers that bypass firm procedures, ignore exception reports, process incomplete instructions, or delay escalation of operational risk.
Exam cue: Prefer timely processing, complete records, segregation of duties, privacy, AML awareness, and exception follow-up.
Risk pitfalls and guardrails
