Frequently Asked Questions
What is the multiplier for standard stock options contracts?▼
In the United States equity markets, each standard options contract controls exactly 100 shares of the underlying stock.
What happens if an option expires in-the-money by $0.01?▼
The Options Clearing Corporation (OCC) automatically exercises any equity option that is at least $0.01 in-the-money at expiration unless instructed otherwise.
What is the difference between intrinsic value and extrinsic value?▼
Intrinsic value is the immediate in-the-money worth if exercised today; extrinsic value reflects the time value and implied volatility remaining until expiration.
Can I lose more than my initial investment buying a call or put?▼
No. When buying (going long) calls or puts, your maximum possible financial loss is strictly limited to the upfront premium paid.
