Portfolio Margin (Risk-Based) vs. Regulation T Strategy Margin
Compared to traditional Regulation T margin accounting, what is the primary operational advantage of Portfolio Margin for sophisticated options and equity accounts?
Portfolio margin calculates margin based on net portfolio risk using theoretical pricing models (TIMS). For hedged portfolios (e.g. options offsetting equity risk), portfolio margin dramatically lowers capital requirements compared to Reg T strategy-based rules.
Complete Analysis & Legal Rationale
Eligibility requires approval for uncovered options and high account equity (typically $100,000 to $500,000 minimum).
Distractor Autopsy (Why Other Options Are Traps)
FINRA exam writers design incorrect distractors using specific calculation mistakes and regulatory misconceptions. Review why each option succeeds or fails:
Accurately describes TIMS risk-based margin model and capital efficiency for hedged portfolios.
Maintenance calls still occur if net portfolio risk exceeds thresholds.
Extensive margin and risk disclosure agreements are strictly mandatory.
Penny stocks are not eligible for portfolio margin.
