降低风险的一个办法是购买股票的同时卖出该股的看涨期权。

One way to reduce that risk is to buy stocks now but also sell calls on those stocks, a strategy known as selling covered calls.

人力资本应属于“看涨期权”，物资资本所有者购买人力资本所支付的价值相当于期权的权利金。

When the owner who possesses the material capital pays for the human capita, the value is as equal as the option premium.
