Short or selling a Put is the opposite of buying a Put. An investor buys a Put when they are bearish on a stock. An investor sells a Put when they are bullish about the stock and expects the stock price to rise or stay sideways at the minimum.

When you sell a Put, you earn a premium (from the buyer of the Put). You have sold someone the right to sell you the stock at the strike price. If the stock price increases beyond the strike price, the short put position will make a profit for the seller by the amount of the premium, since the buyer will not exercise the Put option and the Put seller can retain the premium (which is their maximum profit). However, if the stock price decreases below the strike price, by more than the amount of the premium, the Put seller will lose money. The potential loss is unlimited (until the stock price falls to zero).

• When to Use: The investor is very bullish on the stock/index. The main idea is to make short-term income.

• Risk: Put strike price – Put premium.

• Reward: Limited to the amount of premium received.

• Breakeven: Put strike price - Premium

Example:

Mr. XYZ is bullish on the Nifty 50, which is currently trading at ₹22,150. Based on this view, he sells a Put option with a strike price of ₹22,000 at a premium of ₹180, with an expiry of 30th April. Since he receives the premium upfront, his total premium income comes to ₹9,000 (₹180 × 50 lot size). If the Nifty index stays above ₹22,000 till expiry, the Put buyer will not exercise the option, and Mr. XYZ will retain the entire premium as profit. However, if the Nifty falls below ₹22,000, the Put buyer will exercise the option, and Mr. XYZ will start incurring losses as he is obligated to buy at the higher strike price. The breakeven point for this trade is ₹21,820 (₹22,000 – ₹180). If the Nifty falls below this level, Mr. XYZ will lose not only the premium earned but also incur additional losses depending on how much the index falls. For instance, if the Nifty drops to ₹21,500, his effective loss would be ₹320 per unit (₹500 loss - ₹180 premium), resulting in a total loss of ₹16,000 (₹320 × 50).

Analysis: Selling Puts can lead to regular income in a rising or range-bound market. But it should be done carefully since potential losses can be significant if the price of the stock/index falls. This strategy can be considered an income-generating strategy.
