What does it mean that one options contract controls 100 shares?

In the U.S. market, options use a multiplier of 100. This means that if you see an option premium quoted at $3.50, the actual cost to purchase that contract is $350. This multiplier is a critical detail for beginners to internalize because it significantly impacts the amount of capital required to enter a trade and the total risk exposure of the position.

What is the difference between intrinsic and extrinsic value?

Intrinsic value is the "right now" or "real" value of an option; for example, if a stock is at $190 and you hold a call option with a strike price of $185, the intrinsic value is $5. Extrinsic value, also known as time value, represents the "potential" value based on the time remaining until expiration and the stock's volatility. While intrinsic value is based on the current stock price, extrinsic value is a "wasting asset" that decays every day until it eventually hits zero at expiration.

Why is the "50/21 Rule" recommended for managing trades?

The 50/21 rule is a disciplined strategy designed to protect profits and avoid the most volatile periods of an option's life. It suggests that a trader should take profits once they have achieved a 50% gain and should close or "roll" their position when there are 21 days left until expiration. By exiting at the 21-day mark, traders avoid "the gamma zone," where price swings become unpredictable and the rate of time decay (Theta) accelerates rapidly.

What is the difference between buying a Call and buying a Put?

A Call option is a bullish strategy that gives the buyer the right to purchase a stock at a set strike price, allowing them to profit if the stock price rises significantly. A Put option is the mirror image, giving the buyer the right to sell a stock at a specific price. Puts are often used as "insurance" or a "Protective Put" to hedge a portfolio, as they gain value when the underlying stock price falls, effectively setting a floor on potential losses.

What are "The Greeks" and why do they matter?

The Greeks are mathematical measurements that act as gauges for an option's price sensitivity. Delta measures how much the option price moves for every $1 change in the stock; Gamma tracks the acceleration of that movement; Theta represents the daily time decay or "rent" paid to hold the contract; and Vega measures sensitivity to implied volatility. Understanding these forces helps traders understand why an option's price might change even if the underlying stock price remains stagnant.
