Options Volatility and Pricing (Natenberg)

What are stock options and how do they work?

Options give you the right (not obligation) to buy (call) or sell (put) a stock at a specific price (strike) by a specific date (expiration). Calls profit when stocks rise; puts profit when stocks fall. Options amplify both gains and losses — you can lose 100% of your investment. Start with covered calls and cash-secured puts to learn. Never sell naked options as a beginner.

Which broker is best for options trading?

tastytrade and thinkorswim (Schwab) are the top choices for options traders. tastytrade specializes exclusively in options and futures with low per-contract fees ($1 to open, $0 to close), powerful tools, and an education-focused approach. thinkorswim offers the most robust options chain analysis and strategy builder. Interactive Brokers is best for professionals who trade large volume at very low fees.

What are options in investing?

Options are financial contracts that give the buyer the right — but not the obligation — to buy or sell an underlying asset at a specified price (the strike price) before a set expiration date. Each options contract covers 100 shares. Options can be used to speculate on price movements, hedge existing positions, or generate income. They are more complex than stocks and carry unique risks.

What is the risk of buying options?

When you buy a call or put, your maximum loss is limited to the premium you paid for the contract. However, options can expire completely worthless if the stock does not move far enough in your direction before expiration — making it possible to lose 100% of your investment. Options also decay in value over time (theta decay), working against buyers even if the stock moves your way slowly.
