What Are Options?
A contract giving you the right, not the obligation, to buy or sell a stock at a set price — leverage and flexibility a plain share doesn't offer.
An option is a contract, not a share of stock itself — it gives the holder the right (but never the obligation) to buy or sell 100 shares of an underlying stock at a fixed price (the strike price), on or before a set date (expiration). A call option is the right to buy; a put option is the right to sell. The seller of that contract, on the other side of the trade, takes on the actual obligation if the buyer chooses to exercise it.

| Call Option | Put Option | |
|---|---|---|
| Gives the holder the right to | Buy the stock at the strike price | Sell the stock at the strike price |
| Typically bought when expecting | The stock to rise | The stock to fall |
| Maximum loss (as the buyer) | The premium paid for the contract | The premium paid for the contract |
Three broad reasons show up repeatedly: leverage (controlling 100 shares' worth of exposure for a fraction of the cost of buying them outright), hedging (protecting an existing stock position against a decline, similar in spirit to insurance), and income (selling options against stock already owned, covered in the Income Strategies lesson later in this track).
A stock trades at $100. Buying 100 shares outright costs $10,000. A call option giving the right to buy those same 100 shares at $105 might cost only $300. If the stock rises to $115, the 100 shares gained $1,500 (15% return on the $10,000). The option, meanwhile, is now worth roughly $1,000 (the $10 of intrinsic value above the $105 strike, times 100 shares) — more than tripling the $300 paid, a far larger percentage gain from a much smaller amount of capital. The same leverage cuts both ways: if the stock stays flat or falls, the option can expire completely worthless, losing 100% of the $300, while the 100 shares would have lost nothing at all.
- The buyer of an option has a right, never an obligation — the most it can cost the buyer is the premium paid, regardless of how badly the trade goes.
- The seller of an option takes on a real obligation, and that obligation's risk profile is very different (in some cases open-ended) — a distinction covered in detail in the Income Strategies lesson.
- Leverage is the core mechanic behind both the appeal and the danger of options — the same feature that turns a small move into a large percentage gain turns a small miss into a total loss of the premium.
