$1.5倍做多波动率指数短期期货ETF-ProShares(UVXY)$
这货一直跌，大家为什么不买空呢，这不是明白挣钱的嘛，近期15块多的高点，到现在也翻了3倍，不是吗？

我就纳闷了，我给你们算算，假设恐慌指数价格为100美元，你买入1股市值为100美元，指数价格由100美元下跌到50美元，到下一个交易日指数的价格为50美元，你的本金变成150美元，此时指数再跌50%价格跌到25美元，你的市值变成150美元*150%=225美元，不是翻倍了吗，我算的可有错

你举的例子，不是那么算的。假设你空（卖掉）一股100元，得到现金100元，此时保证金（成本）也是100元。然后最终股价跌到25元，你以25元平仓（买入），那么你的 收益=卖空得到的现金-平仓花费的金额，也就是100-25=75元，利润率=75/100=0.75。记住了，做空收益有限（最多一倍），风险无限

做空理论上，最多赚一倍（股价跌到0），不懂可以百度。

做空跌到1分钱也不会翻倍啊！
