A strip is delta negative trading strategy. Being delta negative implies that the value of the strip position increases when the price of the underlying security goes down.
A strip is constructed by adding an extra put leg to a long straddle. So, it consists of two at the money put options and one at the money call option.
The buyer of a strip has to pay a cost premium upfront, but he expects the market to make a move in one direction before the expiry. He expects the probability of a down move to be more than that of an up move.
The risk to reward of a strip is beneficial to the long trader if a strong move happens. The maximum loss is limited to the premium paid up front, while maximum profit is unlimited.
