BULLISH
Cash-Secured Put Strategy Lab
What is a cash-secured put?
A cash-secured put involves writing a put option and simultaneously setting aside the cash to buy the stock if assigned.
This is a bullish to neutral strategy used to generate income or to acquire the stock at a lower, more favorable price.
If the stock drops below the strike price, you will be assigned and must buy the stock.
Execution Legs:
1
Ensure you have enough cash in your account to buy 100 shares of the stock at the strike price.
2
Sell a put option at a strike price where you'd be comfortable owning the stock.

Institutional Playbook & Ideal Timing
🎯 Ideal Timing & Volatility Environment:
High IV regime (IV Rank > 50%) where options premiums are overpriced. Ideal right before/after earnings for IV crush, during elevated market fear/VIX spikes, or in rangebound consolidation between Put and Call Walls.
🎯 Strike & DTE Target:
45 to 60 DTE. Buy ATM 50-delta Call to minimize theta decay while maintaining high delta participation.
🛡️ Exit & Risk Rules:
Take profit at 50% of max profit (for credit/neutral) or 100%–200% ROI (for debit). Cut losses at 100% of debit paid (or 2x credit collected). Close before expiration if delta expands beyond 70.

Directional Bias (Δ)
