Buying a Put is the opposite of buying a Call. When you buy a Call you are bullish about the stock / index. When an investor is bearish, he can buy a Put option. A Put Option gives the buyer of the Put a right to sell the stock (to the Put seller) at a pre-specified price and thereby limit his risk.
A long Put is a Bearish strategy. To take advantage of a falling market an investor can buy Put options.
When to use: Investor is bearish about the stock / index.
Risk: Limited to the amount of Premium paid. (Maximum loss if stock / index expires at or above the option strike price).
Reward: Unlimited
Break-even Point: Stock Price – Premium
Example: Mr. XYZ is bearish on Nifty on 24th June, when the Nifty is at 2694. He buys a Put option with a strike price Rs. 2600 at a premium of Rs. 52, expiring on 31st July. If the Nifty goes below 2548, Mr. XYZ will make a profit on exercising the option. In case the Nifty rises above 2600, he can forego the option (it will expire worthless) with a maximum loss of the premium.
ANALYSIS: A bearish investor can profit from declining stock price by buying Puts. He limits his risk to the amount of premium paid but his profit potential remains unlimited. This is one of the widely used strategy when an investor is bearish.
