Selling a call option without owning the underlying shares. Theoretically unlimited risk since the stock can rise without bound. Requires high margin and active management.

Key takeawayThe riskiest single-leg option trade. Most premium sellers use defined-risk alternatives (call spreads, iron condors) instead.
💡 Why It Matters
The naked call is the riskiest single-leg options trade — unlimited theoretical loss because a stock can rise without bound. Most premium sellers avoid naked calls entirely, preferring call credit spreads or covered calls for bearish/neutral exposure.
⚙ How It Works
Sell a call without owning the underlying shares. If the stock stays below the strike, keep the premium. If the stock rises above the strike, you're obligated to sell shares you don't own — buying at market and delivering at the strike. Loss = (market price − strike − premium) × 100.
📋 Example
SPY at $580. Sell the $600 call for $1.50. SPY rallies to $620. Your loss: ($620 − $600 − $1.50) × 100 = $1,850 per contract. If SPY goes to $650: $4,850 loss. No upper bound. Compare to a $600/$605 call spread: max loss capped at $350 regardless of SPY price.
⚠ Common Mistakes
Selling naked calls on momentum stocks because the premium looks attractive. A stock that can gap 15% overnight (earnings, takeover, short squeeze) creates a loss that no amount of premium income can offset. Use call spreads for defined risk.
