What is an option?

An option is a contract giving the right (not the obligation) to buy or sell a security at a preset price within a deadline.

Call options grant the right to buy, puts the right to sell, at a price called the "strike". For this right you pay a premium. They're leveraged instruments: with a few dollars you control the equivalent of many shares, and you can lose 100% of the premium in days.

Legitimate uses: insuring a portfolio (protective puts), generating income (covered calls). Most common retail use: high-leverage speculation, where the vast majority lose. The US options market moves more notional value than the stock market itself.

Concrete example

An Apple call with a 200 strike expiring in a month might cost $3: if Apple hits 210 it's worth at least 10 (+233%); if it stays below 200 it's worth zero (-100%).
