Learning how to trade options can feel overwhelming at first—especially with all the jargon and complex strategies floating around. But at its core, options trading is a powerful and flexible tool that, when understood correctly, can help you manage risk, generate income, or amplify returns. Whether you're completely new to investing or looking to expand your knowledge beyond stocks, this guide breaks down everything you need to know about call options and put options, using real-world examples and clear explanations.
By the end, you’ll understand not just what options are, but how they work—and how you can start applying them to your own financial journey.
What Are Options? Understanding the Basics
An option is a financial contract that gives the buyer the right—but not the obligation—to buy or sell an underlying asset (like a stock) at a specific price, on or before a certain date. The seller (or "writer") of the option takes on the obligation to fulfill the contract if the buyer chooses to exercise it.
There are two main types of options:
- Call Options: Give the holder the right to buy the underlying asset.
- Put Options: Give the holder the right to sell the underlying asset.
Unlike buying stocks, where you own a piece of a company, options are derivative instruments—meaning their value is derived from another asset.

Call Options Explained (With Example)
Let’s say you believe Apple (AAPL) stock, currently trading at $170, is going to rise in the next few weeks.
Instead of buying 100 shares outright (which would cost $17,000), you could buy a call option.
Here’s how it works:
- You purchase one call option contract for Apple with a strike price of $175, expiring in 30 days.
- The premium (price) for this option is $2.00 per share.
- Since one options contract covers 100 shares, your total cost is $200 ($2.00 × 100).
Now, two scenarios:
Scenario 1: Stock Price Rises Above Strike Price (In-the-Money)
Apple jumps to $190 before expiration.
- You can exercise your option and buy 100 shares at $175 (the strike price), even though the market price is $190.
- You can then sell those shares at $190, making an $1,500 profit on the spread ($190 – $175 = $15 × 100).
- Subtract your initial $200 premium: **net profit = $1,300**.
Alternatively, you can simply sell the option contract itself, which will now be worth much more due to the increased stock price—no need to buy the shares.
Scenario 2: Stock Price Stays Below Strike Price (Out-of-the-Money)
Apple stays at $172 or drops.
- Your option expires worthless.
- You lose only the $200 premium paid.
- This limited risk is one of the key advantages of being an option buyer.
Put Options Explained (With Example)
Now imagine you’re bearish on Tesla (TSLA), currently trading at $250. You think it might drop due to upcoming earnings.
You decide to buy a put option:
- Strike price: $240
- Expiration: 45 days away
- Premium: $4.50 per share
- Total cost: $450 ($4.50 × 100 shares)
Scenario 1: Stock Price Drops Below Strike Price (In-the-Money)
Tesla falls to $220.
- You can exercise your put and **sell 100 shares at $240**, even though the market price is only $220.
- If you don’t own the shares, you can short sell them at $240 and buy back at $220, pocketing the $20 difference per share.
- Total gain: $2,000 – $450 premium = $1,550 profit.
Again, you could also just sell the option contract itself for a higher price instead of exercising it.
Scenario 2: Stock Price Rises or Stays High (Out-of-the-Money)
Tesla goes up to $270.
- Your put option expires worthless.
- Maximum loss: the $450 premium paid.
Key Concepts Every Beginner Should Know
The Contract Multiplier
One options contract always represents 100 shares of the underlying stock. This multiplier is crucial when calculating costs and potential profits.
In-the-Money vs. Out-of-the-Money
- In-the-money (ITM): The option has intrinsic value (e.g., a call option with a strike below current stock price).
- Out-of-the-money (OTM): The option has no intrinsic value; it’s purely speculative.
- At-the-money (ATM): Strike price is close to current market price.
The Options Chain
An options chain is a list of all available call and put options for a given stock, showing strike prices, expiration dates, premiums, and other data. Brokers display this in a clean interface so you can compare choices before trading.
Buyer vs. Seller: Understanding Both Sides
While most beginners start as option buyers, experienced traders often become sellers (also called writers).
| Role | Risk | Reward |
|---|---|---|
| Buyer | Limited to premium paid | Unlimited (calls) or high (puts) |
| Seller | Potentially unlimited (calls) or large (puts) | Limited to premium received |
Selling options can generate consistent income—especially in sideways markets—but comes with higher risk and often requires more capital and margin approval.

Frequently Asked Questions (FAQs)
Q: Are options riskier than stocks?
A: Options can be riskier if not used properly—especially when selling them. However, buying options limits your risk to the premium paid. With education and discipline, options can actually be used to reduce overall portfolio risk.
Q: Can I lose more than I invest in options?
A: If you’re buying options, no—your maximum loss is the premium. But if you’re selling options (especially naked calls), losses can exceed your initial investment. Always understand your position before entering a trade.
Q: Do I need a lot of money to start trading options?
A: Not necessarily. You can start with the cost of a single contract (e.g., $100–$300). However, brokers typically require an approved options trading level, which may involve experience questions and risk disclosures.
Q: What happens when an option expires?
A: If it’s in-the-money by even $0.01, it will usually be automatically exercised. Out-of-the-money options expire worthless.
Q: Can I trade options on any stock?
A: Only on stocks that are optionsable—typically larger, liquid companies like Apple, Amazon, or Tesla. Your broker will show which stocks have available options.
