However, speculators typically do not want to have a short position in the underlying shares, so puts that are purchased to speculate are usually sold before the expiration date.
The maximum potential profit is equal to the strike price of the put minus the price of the put, because the price of the underlying can fall to zero. Risk is limited to the premium paid plus commissions, and a loss of this amount is realized if the put is held to expiration and expires worthless. Buying a put to speculate requires a 2-part bearish forecast. The forecast must predict 1 that the stock price will fall so the put increases in price and 2 that the stock price decline will occur before option expiration.
Buying a put to speculate on a predicted stock price decline involves limited risk and two decisions. The maximum risk is the cost of the put plus commissions, but the realized loss can be smaller if the put is sold prior to expiration.

If there is no offsetting long or owned stock position, then a short stock position is created.

When puts are purchased to speculate, it is assumed that the investor does not want to have a short stock position.
In many cases, in fact, there is not sufficient equity in the account to cover the margin requirement for a short stock position. Therefore, it is generally necessary for speculators to watch a long put position and to sell the put if the target price is reached or if the put is in the money as expiration approaches. A protective put position is created by buying or owning stock and buying put options on a share-for-share basis.
