In plain words: A financial derivative that represents a contract sold by one party to another, offering the right to buy or sell a security.
An option is a contract that gives its holder the right, but not the obligation, to buy or sell an underlying asset at a set price before a certain date. It is a type of derivative and an advanced instrument, far removed from the simple act of owning shares outright.
What are calls and puts?
A "call" option grants the right to buy at a fixed price, while a "put" grants the right to sell at one. Buyers pay a fee, called a premium, for this right and can let the contract expire if it is not worth using. Some investors use options as a hedge to limit downside, while others use them to speculate on short-term price moves.
Why should beginners be cautious with options?
Options have expiry dates and can lose their entire value quickly, which makes them riskier and more complex than holding global equities for the long run. Pricing them well requires understanding volatility, time decay, and probability. They are explained here so you can recognise them as one of the common beginner mistakes to avoid, not as something a long-term, diversified profile needs to use.
Key takeaways
- An option is a contract giving the right to buy or sell at a set price.
- Calls cover buying; puts cover selling; both cost a premium.
- They are complex, time-limited, and higher-risk than owning shares.
