BULLISH
Short Put Strategy Lab
What is a short put?
A naked short put is a bullish to neutral strategy where you sell a put option.
If the stock drops below the strike price, you will be assigned and forced to buy the stock at the strike price, which can result in substantial losses if the stock drops significantly.
Execution Legs:
1
Sell a put option at your desired strike price.
2
Be prepared to purchase 100 shares of the stock if assigned.

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.
