CSP Stock Selection & Returns

Cash-Secured Puts

Key Takeaways

  • Best CSP stocks: ones you genuinely want to own at the strike price.
  • Higher IV = higher premium, but also higher risk of assignment.
  • Track return on capital, not just premium. You're tying up cash as collateral.

TL;DR

Only sell puts on stocks you've researched and would buy at the strike price. Calculate return on capital (premium / cash reserved), not just the raw premium amount. Best candidates: liquid large-caps with moderate IV and strong fundamentals.

The Golden Rule of CSP Selection

Only sell puts on stocks you genuinely want to own at that strike price.

This is the single most important rule. If you're chasing premium on stocks you haven't researched, assignment will catch you off guard, and you'll panic-sell at a loss or hold a stock you don't understand.

Before selling any CSP, ask: "If this stock drops 20% after I'm assigned, would I add more or panic?" If you'd panic, pick a different stock.

Stock Selection Criteria

Market cap > $10B: Large, established companies with lower bankruptcy risk.

Options liquidity: Open interest > 500 on your target strike. Bid-ask spread < $0.10.

IV Rank 20-60%: IV Rank tells you where current IV sits relative to its 52-week range. Below 20% means premium is thin. Above 60% means something unusual is happening (investigate why).

No earnings within 14 days: Unless you specifically want the elevated premium and accept the gap risk.

Fundamental quality: Positive earnings, manageable debt, competitive moat. Don't sell puts on speculative companies.

Calculating Return on Capital

Don't just look at raw premium. Calculate your return on capital tied up.

Formula: Premium collected / Cash reserved × 100 = ROC%

Example: You sell a $100 put for $2.50. Cash reserved: $10,000.

ROC = $250 / $10,000 = 2.5% for 30-45 days

Annualized: ~2.5% × 10 cycles = ~25%

Compare this to the risk-free rate. If your CSP yields 1.5% monthly and a money market pays 0.4%, the extra 1.1% is your compensation for the assignment risk.

Best CSP Candidates by Category

Blue-chip tech: AAPL, MSFT, GOOGL. Moderate IV, strong balance sheets, stocks you'd own for years.

Higher-premium names: AMD, NVDA, TSLA. Elevated IV means richer premiums but more volatile rides.

ETFs for diversification: SPY, QQQ, IWM. Broad diversification, extremely liquid.

Dividend payers: JPM, KO, PG. Lower IV/premium, but if assigned you collect dividends while selling covered calls.

Watch Out

The Capital Trap

CSPs tie up significant capital. A single $150-strike put requires $15,000 in cash. On a $50,000 account, that's 30% of your buying power on one position.

Rules to follow:

  • No single CSP should use more than 20% of your account
  • Keep 30-40% of buying power in reserve
  • Diversify across 3-5 positions minimum
  • Don't sell puts on correlated stocks (e.g., AAPL and MSFT both drop in a tech selloff)
