58. Strangle (Buy Put & Call, Same Expiration Dates, Different Strike Prices; K2 > K1) The farther strike prices are apart, the less the downside risk and the farther the stock price has to move for a profit to be realized Advantage The downside risk if the stock price ends up at a central value is less with a strangle Disadvantage The stock price has to move farther in a strangle than in a straddle for the investor to make a profit The investor is betting that there will be a large price move, but is uncertain whether it will be an increase or decrease. When is this appropriate?
