Bull Put Spread Analyzer

What is a Bull Put Spread?

A Bull Put Spread is an options income strategy where you sell a put at a higher strike and simultaneously buy a put at a lower strike — both with the same expiration date. You collect net premium upfront and profit if the stock stays above your sell strike at expiration.

MAX PROFIT

Net Premium × 100

Stock closes above sell strike

MAX LOSS

(Width − Premium) × 100

Stock closes below buy strike

BREAKEVEN

Sell Strike − Premium

Loss starts below this price

When to Use This Strategy

✓ Ideal Conditions

📈 Bullish or neutral market outlook
⚡ High IV Rank (50%+) — premium is expensive
📅 DTE 35–60 days — optimal theta decay
🏦 Strong company with clear support levels
📊 VIX below 30 — stable macro environment

✗ Avoid When

📉 Clearly bearish trend — stock breaking down
📢 Earnings within the period — avoid binary events
⚠️ VIX above 35 — too much systemic risk
📉 Low IV Rank (below 30%) — premium too cheap
💸 Margin > 5% of portfolio — concentration risk

How to Select Quality Companies — Reducing Risk

The single biggest risk reduction comes from stock selection. Only sell puts on companies you would genuinely want to own. This is the core principle of the Wheel strategy.

FUNDAMENTAL QUALITY

• ROE > 20% — strong returns on equity

• FCF Margin > 15% — generates real cash

• Debt/Equity < 0.5 — low leverage risk

• Gross Margin > 30% — pricing power

• Piotroski F-Score ≥ 6 — financial health

• Revenue growth consistent 3+ years

MARKET POSITION

• Large/Mega cap — NYSE or NASDAQ only

• Market leader in its sector (moat)

• Analyst consensus: Buy or Strong Buy

• Short Float < 10% — low short pressure

• Beta 0.7–2.0 — manageable volatility

• Sector ETF above SMA50 — sector health

TECHNICAL SETUP

• Stock price above SMA50 and SMA200

• Clear horizontal support at or near strike

• RSI not extremely overbought (>80)

• No major resistance directly above entry

• Volume confirming direction

• Place sell strike at or below support

EXAMPLES — QUALITY NAMES

✓ MSFT, AAPL, GOOGL — mega cap tech

✓ ASML, AMAT, LRCX — semis equipment

✓ NVDA (when IV high) — with tight spread

✓ AMZN, ANET, VEEV — cloud/software moat

✗ Meme stocks, biotech, micro caps

✗ Stocks near earnings announcement

Risk Management Rules

💰

Position sizing

Never exceed 5% of portfolio margin per position. Maximum 40% of total margin in one sector. This limits catastrophic loss from sector-wide moves.

🛑

Stop-loss rule

Close the position if loss reaches 100% of premium collected. Example: collected $300 premium → close if spread costs $600 to buy back. This limits max loss to ~$300, not the full $700.

🎯

Profit taking

Close at 50% of maximum profit. If you collected $300, close when spread is worth $150 to buy back. This frees up margin and reduces time in trade.

📅

DTE management

Enter at 35–60 DTE. Consider closing or rolling at 21 DTE to avoid gamma risk. Never hold through earnings unless using the Wheel strategy with full assignment readiness.

🔄

Rolling losing positions

If the stock approaches your sell strike, consider rolling down and out — move to a lower strike at a further expiry for a net credit. Only roll if the thesis is still intact.

Example Trade — LRCX

Lam Research trading at $260. IV Rank 66%. Selling a Bull Put Spread:

Sell 1x LRCX $260 Put @ $21.34 mid

Buy 1x LRCX $250 Put @ $16.55 mid

─────────────────────────────

Net Premium: $4.79 × 100 = $479 received

Max Loss: ($10 − $4.79) × 100 = $521

Breakeven: $260 − $4.79 = $255.21

Buffer: (260 − 255.21) / 260 = 1.8%

R:P: 521 / 479 = 1.09:1 ← Excellent

Ann. yield on margin: ~197% / year
