What is a Short Straddle? A Simple Guide
A short straddle is a volatility-selling strategy where you sell a call and a put at the same strike and expiry. It profits when the underlying stays near the strike and time decay erodes both options. Its risk is open-ended if the price moves sharply.
A short straddle is the opposite of a long straddle: it profits when the market stays still. But that income comes with open-ended risk.
What follows is a no-nonsense guide for Indian traders. You can trade it on Stockk.

How does a short straddle make money?
Picture this: NIFTY trades at 22,600 and is expected to stay calm. You sell the 22,600 call at ₹180 and the 22,600 put at ₹180, collecting ₹360. That ₹360 is your maximum profit, earned if NIFTY finishes exactly at 22,600. Losses begin outside the breakevens at 22,240 and 22,960, and beyond those points the loss keeps growing without limit.
What are the risks?
The risk is open-ended on both sides, since a large move makes either the call or put highly valuable against the seller. Losses can far exceed the premium collected, which is why margins are high and risk control is essential. A short straddle is among the riskier strategies.

The open-ended risk means a single sharp move can wipe out many days of premium income. Exchanges enforce high margins to cover this danger. This is a strategy for experienced, well-capitalised traders with strict risk control, not for beginners.
