Option Premium
Options
是什么意思
The price you pay per share to buy an option contract. The total cost of the option is the premium per share multiplied by 100 (the standard contract size) and the number of contracts you buy. The premium is made up of intrinsic value (if the option is in the money) and time value (the extra amount traders pay for the chance the option will move further into the money before expiration).
举例
You buy 2 call options with a premium of $3.50 per share. The total cost of the trade is $3.50 × 100 shares × 2 contracts = $700. This $700 is your maximum possible loss if the options expire worthless.
新手常犯的错
Beginners focus on the per-share premium and forget that each contract represents 100 shares. A $2 premium sounds cheap until you realize it costs $200 per contract, so 5 contracts would cost $1,000 total.
