关于空头套利内容导航：
1、空头套利
Short selling is a trading strategy that involves borrowing a security from a broker and selling it on the open market, with the expectation that the price will decline. The investor then buys back the security at a lower price and returns it to the broker, pocketing the difference as profit. Short selling is a risky strategy, as the investor is exposed to unlimited losses if the price of the security rises instead of falling.
2、空头套利是什么意思
空头卖出，多头买入
3、空头套利保值
持有空头看跌期权，也就是卖出看跌期权，这个时候你是多头，利用股指期货套期保值 拿就应该是卖出套期保值
你有空头看跌期权，也就是说价格上涨你有可能亏损，套保当然是做多了。明白了不？
一般是用期权为期货保值。一旦持有期权空头头寸（卖出看涨或者买进看跌期权）就是给股指期货的多头保值的。 不过一般选用买进看跌期权而不用卖出看涨期权保值。
说的是对的。不过仓位及点差一定要一样才有对冲作用，不过你还是没有赚。
