What Are Options?
Options are financial contracts that give you the right (but not the obligation) to buy or sell an underlying asset at a specific price (strike price) before a certain date (expiration). Unlike stocks, options have limited risk when buying and unlimited profit potential in the right direction.
Options are priced based on several factors including the underlying asset's price, strike price, time until expiration, volatility, and interest rates. Understanding how these factors affect option prices is crucial for successful options trading.
Key Concept: Time Decay
Options lose value as they approach expiration—this is called time decay or theta decay. Time decay accelerates as expiration approaches. When buying options, you're fighting time decay. When selling options, time decay works in your favor.
Calls vs. Puts Explained
There are two basic types of options:
Call Options
Call options give you the right to buy the underlying asset at the strike price. You buy calls when you're bullish—you profit if the asset price rises above the strike price plus the premium paid. Maximum loss is limited to the premium paid.
Put Options
Put options give you the right to sell the underlying asset at the strike price. You buy puts when you're bearish—you profit if the asset price falls below the strike price minus the premium paid. Maximum loss is limited to the premium paid.
| Option Type | When to Use | Profit Potential |
|---|---|---|
| Call Options | Bullish outlook | Unlimited (theoretically) |
| Put Options | Bearish outlook | Limited to strike price minus premium |
Understanding the Greeks
The Greeks measure how option prices change in response to various factors:
1. Delta
Measures how much the option price changes for each $1 move in the underlying asset. Call deltas range from 0 to 1, put deltas range from -1 to 0. At-the-money options have deltas around 0.5 (calls) or -0.5 (puts).
2. Gamma
Measures how much delta changes as the underlying price moves. Gamma is highest for at-the-money options and increases as expiration approaches. High gamma means delta changes rapidly with price movements.
3. Theta
Measures time decay—how much the option loses value each day. Theta is negative for long options (you lose money each day) and positive for short options (you make money each day from time decay). Theta accelerates as expiration approaches.
4. Vega
Measures sensitivity to volatility changes. Higher volatility increases option prices (positive vega for long options). Vega is highest for at-the-money options with longer time to expiration. Understanding vega helps you trade volatility.
Basic Options Strategies
Start with these basic options strategies:
1. Buying Calls (Long Call)
The simplest strategy: buy a call option when you're bullish. Limited risk (premium paid), unlimited profit potential. Best for strong directional moves. Time decay works against you, so this strategy requires price movement in your favor.
2. Buying Puts (Long Put)
Buy a put option when you're bearish. Limited risk (premium paid), profit if price falls. Used for protection or bearish speculation. Like long calls, time decay works against you.
3. Covered Calls
Sell call options against stock you own. Generates income but limits upside. If the stock rises above the strike, you may be forced to sell. This strategy is good for generating income on stocks you're willing to sell at a specific price.
Options Trading Risks
Options trading involves significant risks:
- Time Decay: Options lose value over time, even if the underlying price doesn't move
- Volatility Risk: Option prices are sensitive to volatility changes
- Liquidity Risk: Some options have low liquidity, making it hard to enter or exit positions
- Assignment Risk: When selling options, you may be assigned and forced to buy or sell the underlying asset
Important Warning
Options trading can result in the loss of your entire investment. Never risk more than you can afford to lose. Start with paper trading to learn before risking real money. Understand all risks before trading options.
Frequently Asked Questions
How much money do I need to start trading options?
Brokerage requirements vary, but many brokers allow options trading with accounts as small as $2,000. However, you should have significantly more capital to trade options safely. Options can expire worthless, so you need enough capital to withstand losses. Start with small positions and paper trading to learn before committing significant capital.
What's the difference between buying and selling options?
Buying options gives you the right but not the obligation to buy or sell. Your risk is limited to the premium paid. Selling options (writing options) gives others the right to exercise against you. When selling options, your risk can be unlimited (for naked calls) or substantial (for naked puts). Selling options requires more capital and experience.
How do I choose which strike price and expiration?
Strike price choice depends on your outlook and risk tolerance. In-the-money options cost more but have higher deltas (move more with the underlying). Out-of-the-money options cost less but require larger price moves to profit. Expiration choice balances time decay against the time needed for your price target. Longer expirations cost more but give more time for the trade to work.
