Put ratio spread is a multi-leg, neutral strategy with undefined risk and limited profit potential that involves buying in-the-money put options and selling more out-of-the-money put options of the same underlying and expiry but at a different strike price. If the strategy is initiated for a credit, the trader can earn in two ways: the premium received while executing the strategy and the width of the spread between the long and short put options. If the strategy is initiated for a net debit, the trader will only profit when the underlying prices fall to the short put option and the trader gains from the spread between the long and short put options.
Max loss can be seen if the price of the underlying asset takes a sudden nose dive below the breakeven point. The loss would be limited yet significant till the security price becomes worthless.
Max gain would be realized if the underling price at expiry fall to short put option strike price. The short puts will expire worthless and gains would be made from difference between long and short strike put.
