A Long Put is a position when somebody buys a put option. It is in and of itself, however, a bearish position in the market. Investors go long put options if they think a security's price will fall.There are two main reasons why investors might choose to buy puts instead of selling short the underlying security: -1-The first reason has to do with risk: when you sell short, you're exposed to potentially unlimited losses if the stock price rises; with a long put, your maximum loss is limited to the premium you paid for the option.2-The second reason has to do with leverage: buying puts allows you to control 100 shares of stock for every one contract that you purchase, whereas selling short requires that you actually borrow shares from someone else (and pay interest on that loan).
