What Is a Naked Option?
A naked option (also called an uncovered option) is when you sell a call or put option without holding the underlying asset or another offsetting position to cover your potential obligation. Unlike a covered call where you own the shares, a naked option leaves you fully exposed to unlimited or large losses if the market moves against you.
Naked Call vs. Naked Put
- Naked call: You sell a call option without owning the underlying stock. If the stock rises sharply, you must buy the shares at market price and deliver them at the lower strike price, creating theoretically unlimited losses.
- Naked put: You sell a put option without holding a short position or cash equivalent. If the stock crashes, you must buy the stock at the strike price, which could be far above the current market price, creating large losses.
Why Traders Write Naked Options
Naked option writing is attractive because it generates upfront premium income with a high probability of profit. In Indian markets, OTM weekly Nifty or Banknifty naked options expire worthless most of the time, making it a popular but high-risk strategy. Experienced traders use it when they have strong conviction that the market will stay range-bound.
Margin Requirements in India
Because of the high risk, SEBI and NSE require substantial margins for naked option writing. Margin for a naked Nifty call or put can range from Rs 80,000 to over Rs 2,00,000 per lot depending on volatility. The margin consists of SPAN margin (to cover potential losses) plus exposure margin (additional buffer). Insufficient margin leads to forced square-off by the broker.
The Risk Reality of Naked Options
Naked option sellers collect small premiums regularly but face the risk of "black swan" events: a sudden large market move that results in losses far exceeding several months of premium income. Examples from Indian markets include the March 2020 COVID crash, demonetization in 2016, and election-day volatility. Many retail traders who sold naked options on such days faced catastrophic losses.
Key Takeaway
Naked option writing is a strategy best suited for experienced, well-capitalized traders with strict risk management systems. The asymmetric risk, where potential losses far outweigh premium collected, makes it unsuitable for beginners. If you want to sell options, start with defined-risk strategies like credit spreads rather than naked positions.
