Covered Calls vs Cash-Secured Puts: Yield, Risk & Tax Comparison

Long underlying equity overwriting vs cash collateralized option selling for systematic income generation

Governing Equation & Conversion Identity Deterministic Formula
Synthetic Equivalence (Put-Call Parity): Long Stock + Short Call = Short Put + Cash (C - P = S - K*e^(-rT))

A mathematical and institutional comparison of covered call writing against cash-secured put selling. Explores Delta assignment probabilities, capital efficiency, downside breakeven levels, and IRS Qualified Covered Call tax treatment.

Technical Tradeoff & Benchmark Matrix

Strategy Dimension Covered Call (Buy-Write) Cash-Secured Put (Short Put)
Capital Required 100 shares of underlying equity per contract 100% cash collateral (Strike x 100)
Primary Market Bias Neutral to Moderately Bullish Neutral to Moderately Bullish (Willing buyer at strike)
Max Upside Potential (Strike - Stock Price + Option Premium) x 100 Option Premium Collected x 100
Downside Breakeven Stock Purchase Price - Option Premium Option Strike Price - Option Premium
Assignment Outcome Shares called away at strike price; cash delivered Assigned 100 shares of stock at strike; cash debited
Greeks Exposure Long Stock Delta minus Short Call Delta (+0.70 to +0.80 net Delta) Positive Short Put Delta (+0.20 to +0.30 Delta)
IRS Tax Rules IRC Section 1092 Qualified Covered Call rules prevent straddle holding freeze Premium is short-term capital gain on lapse or reduces stock basis if assigned

Frequently Asked Questions & Technical Analysis

Q: Are covered calls and cash-secured puts synthetically identical?

Yes. According to Put-Call Parity, holding 100 shares of stock and selling a call option produces the exact same profit and loss graph as selling a put option at the same strike and expiration backed by cash. The difference lies in capital allocation and existing stock ownership.

Q: Which strategy is better in a flat or sideways market?

Both strategies excel in sideways markets due to positive Theta time decay. A covered call generates dividend income plus option premium, while a cash-secured put earns money market interest on cash collateral in addition to the option premium.
