An option gives its buyer the right, but not the duty, to buy or sell an asset at a predetermined price before a set date.
Two sides, two different constructions
The option buyer risks only the premium paid. The maximum loss is known in advance and bounded.
The option seller receives the premium immediately and takes on the obligation to perform if the buyer demands it. Their profit is capped at the premium; their loss is not capped at all.
Two types
A call gives the right to buy, a put the right to sell. Combinations of them build almost any payout profile, and it is that flexibility that makes options complex.
What the premium depends on
The distance between the current price and the strike, the time to expiration, and expected volatility. The last is the main source of surprise: an option can get cheaper while the price moves your way, if volatility fell further.
Time decay
An option loses value as expiration approaches. For a buyer that is a constant headwind: being right has to materialise before expiry.
Who needs this
For hedging an existing position, the instrument is being used as intended. For speculation it demands an understanding that reading one article does not confer.
A beginning investor does not need options. Related: Futures: an obligation, not an option and Hedging: insurance paid for with return.

- Why leverage ruins the result even when the forecast is rightBorrowed money amplifies the return and, along with it, the chance of losing the position before being right pays off.
- Expiration: what happens on the contract's last dayA cash-settled contract closes in money, a physically settled one in the real asset. Confusing them is expensive.
- Hedging: insurance paid for with returnReducing risk through an offsetting position. It works, it costs money, and it is often used for the wrong purpose.
- Structured products: where the risk is hiddenAn instrument with declared capital protection and capped income. It can only be understood by reading the terms in full.
