Investopedia explains 'Short Straddle'
If a trader writes a straddle with a strike price of $25 and the price of the stock jumps up to $50, the trader would be obligated to sell the stock for $25. If the investor did not hold the underlying stock, he or she would be forced to buy it on the market for $50 and sell it for $25.
The short straddle is a risky strategy an investor uses when he or she believes that a stock's price will not move up or down significantly. Because of its riskiness, the short straddle should be employed only by advanced traders due to the unlimited amount of risk associated with a very large move up or down.
