This one bets the other way. Sell AMD first after it has risen a long way, when its close is 20 percent above its average price over the last 25 trading days. The idea is that the price will fall back to that average. Buy it back when it gets back to the average, or buy it back at a small loss if it rises above its recent high first. If neither happens in 20 trading days, buy it back anyway. Short selling can lose more than the starting amount if the price keeps rising.
