PUT RATIO BACKSPREAD

An option trading strategy that combines short puts and long puts to create a position whose profit and loss potential depends on the ratio of these puts. A put ratio backspread is so called because it seeks to profit from the volatility of the underlying stock, and combines short and long puts in a certain ratio at the discretion of the option investor. It is constructed to have unlimited potential profit with limited loss, or limited potential profit with the prospect of unlimited loss, depending on how it is structured. The ratio of long to short puts is typically 2:1, 3:2 or 3:1.
