问题如下：
"Delta hedging a short position in a call option is a 'buyhigh, sell-low' trading strategy." Explain this statement.
选项：
解释：
Delta hedging involves buying 6 shares for each option sold, where 6 is the delta of a long position in the option. As the share price rises, delta increases and more shares have to be bought. As the share price falls, delta decreases and shares have to be sold. The trader is therefore always buying after a price increase and selling after a price decrease.
这道题如果不是从定义去理解，可不可以理解为，当现货价格上涨，short call损失严重，所以要买更多的股票对冲，如果现货价格跌，继续持有股票会亏损，所以要卖？
