A naked call is one of the riskiest options strategies you can trade. It involves selling call options without owning the underlying shares. While it can be profitable, the potential for unlimited losses makes it unsuitable for most retail traders. This guide explains exactly how naked calls work and why they are so dangerous.
What is a Naked Call?
A naked call (also called an uncovered call) is when you sell a call option without owning the underlying 100 shares. You collect premium, but if the stock rises significantly, you must buy shares at the market price and deliver them at the strike price, potentially losing far more than you made.
The key danger: A stock can theoretically rise to infinity. If you sold a naked call and the stock triples overnight, you owe the difference. Your losses have no limit.
How Naked Calls Work
You sell a call option at a strike price above the current stock price
You collect the premium immediately
You do not own the underlying shares
At expiration, one of two things happens:
Stock stays below strike: The call expires worthless. You keep the premium.
Stock goes above strike: You must buy 100 shares at market price and deliver them at the strike price. You lose the difference.
Example: How Naked Calls Can Devastate You
Stock ABC is at $50. You sell a $55 call for $2.00, collecting $200.
Good scenario: Stock stays at $50. You keep $200. Nice.
Bad scenario: Company announces it is being acquired at $120 per share. Stock gaps up overnight.
- You must deliver shares at $55
- You buy shares at $120
- Loss: ($120 - $55) x 100 = $6,500
- Minus premium: $6,500 - $200 = $6,300 net loss
You made $200 but lost $6,300. One trade wiped out 31 winning trades.
Naked Call vs Covered Call
These are both short call positions but with completely different risk profiles:
| Covered Call | Naked Call | |
|---|---|---|
| Own shares? | Yes, 100 shares | No |
| Maximum loss | Stock goes to $0 | Unlimited |
| If assigned | Sell your shares | Buy at market, sell at strike |
| Approval needed | Basic | Highest level |
| Suitable for | Most traders | Experienced only |
Why Anyone Would Trade Naked Calls
Given the risks, why would anyone sell naked calls? Here are the reasons professional traders sometimes use them:
- Capital efficiency: No need to tie up capital in shares
- Time decay: You benefit as the option loses value each day
- High probability: Out of the money calls often expire worthless
- Part of a strategy: Combined with other positions to manage risk
Reality check: Professional traders who use naked calls typically have strict risk management rules, large accounts with margin cushion, and often hedge their positions with other instruments. They accept occasional large losses as part of their overall strategy.
The Math Problem
Naked calls have an asymmetric risk-reward that works against you:
- Win: You keep the premium (limited)
- Lose: You pay the difference between market and strike (unlimited)
Let us say you win 90% of your naked call trades, making $200 each time. That is $1,800 from 9 winners. Then you lose $6,000 on the 10th trade. Net result: -$4,200. The math does not work unless you can cut losses before they get catastrophic.
Real World Disasters
History is full of naked call disasters:
- Short squeezes: When heavily shorted stocks spike, naked call sellers get destroyed
- Acquisition announcements: Buyouts at a premium can double or triple a stock overnight
- Earnings surprises: Stocks can gap up 30-50% on blowout earnings
- FDA approvals: Biotech stocks can go up 200% on drug approval news
In all these cases, naked call sellers face losses many times greater than any premium they collected.
Safer Alternatives
If you want short call exposure with defined risk, consider these alternatives:
- Covered calls: Own the shares first, then sell calls
- Bear call spread: Sell a call and buy a higher strike call to cap losses
- Iron condor: A spread that limits risk on both sides
Better Alternative: Bear Call Spread
Instead of a naked call, use a spread:
- Sell the $55 call for $2.00
- Buy the $60 call for $0.75
- Net credit: $1.25 ($125)
- Maximum loss: $5 spread - $1.25 credit = $3.75 ($375)
You make less, but your worst case is $375, not unlimited.
Requirements for Trading Naked Calls
- Margin account required
- Highest options approval level (usually Level 4 or 5)
- Significant account size (brokers often require $25,000+)
- Experience trading options
- Understanding of margin and maintenance requirements
If You Still Want to Trade Naked Calls
- Never sell naked calls on volatile stocks: Avoid meme stocks, biotechs, or anything that can spike
- Sell far out of the money: Higher probability, smaller premium
- Use small position sizes: One catastrophic loss should not blow up your account
- Have stop losses: Buy back the call if it goes against you
- Avoid earnings: Close positions before announcements
- Monitor constantly: You need to react fast if things go wrong

Summary
A naked call is selling a call option without owning the underlying shares. You collect premium but face unlimited risk if the stock rises significantly. This strategy is only appropriate for experienced traders who understand and can manage the risks. Most retail traders should avoid naked calls entirely and use covered calls or spreads instead.
