Options are financial derivatives traded over 40 million times daily, making them a cornerstone of modern finance. But what exactly are they, and why do they matter?
This guide breaks down calls, puts, strike prices, moneyness, and premiums in plain English—perfect for beginners. Let’s demystify options step by step.
What Is an Option?
An option is a contract granting the right (but not obligation) to buy or sell an asset at a preset price (strike price) by a future date (expiration).
Key Terms:
- Call Option: Right to buy an asset (e.g., stocks).
- Put Option: Right to sell an asset.
- Underlying Asset: The security (e.g., Apple stock) tied to the option.
- Strike Price: Fixed price to buy/sell the asset.
- Expiration Date: Deadline to exercise the option.
👉 Example: A call option for 100 Microsoft shares at $120 expiring June 16, 2023, grants the right to buy those shares for $120 each before the expiration.
European vs. American Options
- American Options: Can be exercised anytime before expiration.
- European Options: Can only be exercised on expiration.
Most exchange-traded options are American-style.
Types of Underlying Assets
Options can be tied to:
- Stocks (e.g., Tesla shares).
- Indices (e.g., S&P 500).
- ETFs (e.g., SPDR Gold Trust).
- Commodities (e.g., oil futures).
- Currencies (e.g., EUR/USD).
For simplicity, we’ll focus on stock options.
The Four Basic Option Positions
| Position | Description | Profit When... |
|-------------------|----------------------------------------------|-------------------------------|
| Long Call | Buy right to purchase stock. | Stock price ↑. |
| Long Put | Buy right to sell stock. | Stock price ↓. |
| Short Call | Sell right to others; obligated to sell. | Stock price ↔ or ↓. |
| Short Put | Sell right to others; obligated to buy. | Stock price ↔ or ↑. |
Short sellers earn premiums but take on unlimited risk (e.g., short calls lose if stock soars).
Option Premiums Explained
The premium is the price paid for the option. Influenced by:
- Intrinsic Value: Profit if exercised now (e.g., call strike $50 vs. stock at $60).
- Extrinsic Value: Time, volatility, dividends.
👉 Example: An Apple call at $145 costs $2/share ($200 total for 100 shares). If Apple hits $150, intrinsic value is $5 ($500 gain), netting $300 after premium.
Moneyness: ITM, ATM, OTM
- In-the-Money (ITM): Profitable if exercised (call: stock > strike; put: stock < strike).
- At-the-Money (ATM): Strike = stock price.
- Out-of-the-Money (OTM): Not profitable (call: stock < strike; put: stock > strike).
Options vs. Futures/Forwards
| Feature | Options | Futures/Forwards |
|--------------|-----------------------------|-------------------------------|
| Obligation | Buyer has right; seller must comply. | Both must execute. |
| Cost | Premium paid upfront. | No upfront cost. |
Options offer flexibility; futures lock in obligations.
Real-World Example: Buying a Call
- Trade: Buy 5 Apple $145 calls expiring October for $2/share ($1,000 total).
Outcome: Apple rises to $150 by expiration.
- Exercise right to buy at $145 ($72,500 for 500 shares).
- Sell shares at $150 ($75,000).
- Profit: $2,500 gross ($1,500 after premiums).
Break-even: $147 (strike + premium).
FAQs
1. Are options risky?
Yes, especially for sellers (unlimited losses on short calls). Buyers risk only the premium.
2. How do I profit from puts?
Buy puts when expecting a stock to fall. Profit if the stock drops below the strike.
3. Can I lose more than the premium?
Only if you sell options. Buyers’ losses are capped at the premium paid.
4. What’s the best starter strategy?
Covered calls: Sell calls on stock you own to earn premiums without unlimited risk.
5. How does volatility affect options?
High volatility = higher premiums (more potential for profit).
