What Is a Naked Call?
A naked call (also called an uncovered call) is the riskiest single-option strategy: selling a call option without owning the underlying shares. If the stock rises above the strike price, the seller must buy shares at the market price and deliver them at the lower strike price. Because a stock can theoretically rise without limit, the naked call has unlimited potential loss.
Naked calls are used almost exclusively by professional traders and market makers with sophisticated risk management systems. Most brokers require the highest options approval level (Level 4 or 5) and significant account size to sell naked calls. For most investors, the bear call spread provides similar bearish exposure with defined risk.
Selling naked calls carries theoretically unlimited risk. If the stock price rises sharply (takeover announcement, short squeeze, etc.), losses can far exceed the premium received. A $2 premium on a $100 stock can turn into a $50+ loss per share if the stock jumps to $160. NEVER sell naked calls unless you fully understand and can manage the risk.
Naked Call Risk Formulas
- 1Max profit = $2.00 × 100 = $200 (if stock stays below $110)
- 2Breakeven = $110 + $2.00 = $112
- 3If stock reaches $120: loss = ($120 - $110 - $2) × 100 = $800
- 4If stock reaches $130: loss = ($130 - $110 - $2) × 100 = $1,800
- 5If stock reaches $150: loss = ($150 - $110 - $2) × 100 = $3,800
- 6Risk/reward = Unlimited loss / $200 max gain
- 7Loss at target $130 = $1,800 (9x the max profit)

Why You Should Avoid Naked Calls
- Naked calls are the riskiest standard options strategy
- Most retail traders should NEVER sell naked calls
- Requires highest options approval level and significant margin
- Professional market makers use naked calls but hedge with stock (delta hedging)
- One bad trade can wipe out months or years of premium income
Instead of selling naked calls, consider: (1) Bear call spreads for defined-risk bearish income, (2) Covered calls if you own the shares, (3) Iron condors for neutral income with defined risk. All three provide premium income without unlimited risk.
Naked call margin is typically: max(20% × underlying price - OTM amount + premium, 10% × underlying price + premium) × 100. For a $110 call on a $100 stock sold for $2: approx. $1,200-$2,000 margin per contract. Margin increases as the stock rises, potentially triggering margin calls.
