option premium

基本解释

If the option premium were too low to compensate the writer for the rise, there would be more buyers than sellers, forcing the premium to rise.
如果期权费过低不足以补偿出票方的风险，那么期权的买方就会大于卖方，市场就会迫使期权费上升。
To be profitable, though, at expiration, the stock must be trading for more than 58, the total of the option premium (8 1/2) and the strike price of 50.
当然，要想在到期前真正有利可图，该股票的交易价格必须高于58 1/2，也就是期权溢价（8-1/2）加上商定价格50。
Once the exchange rate is agreed upon between the customer and the bank, no one can come and ask the customer for more money, except the option premium the customer has paid to the bank.
一旦客户与银行的合约中规定了某一汇率，那么，除了支付银行一笔保险今后，就再也不会有人来向客户要一分钱了。

If the option expires worthless, the option premium is extra money in your pocket.
