A stock option is a contract that gives you the right — but not the obligation — to buy or sell a stock at a set price (the strike) by a set date (expiration). You pay a premium for that right. Owning the option is not the same as owning the shares until you exercise.

A call is the right to buy at the strike (useful if you expect the price to rise). A put is the right to sell at the strike (useful if you expect a fall, or to hedge shares you already own). Real markets also price time and volatility into the premium.

Options are leveraged and time-sensitive. If the stock never moves enough in your favor, the contract can expire worthless and you lose the premium. That risk profile is very different from holding shares you bought with StarBux.

StockSt does not have an options market. There are no calls, puts, or premiums to trade here. Practice on StockSt is buy and sell of shares (including capped IPO early buys) — use this lesson to understand options in the real world, then apply share research and sizing on the live listings.

Takeaways

• Option = right, not obligation, at a strike before expiration.
• Calls buy; puts sell — premium can go to zero.
• StockSt has no options market — only share trading.
