An option or future is an agreement whose value depends on another asset. You own a right or an obligation with an expiry date, not a share of a business.

Derivatives are sophisticated tools used well by hedgers and professionals, and they are marketed to individuals as a way to make more from less. I think the marketing gets the relationship backwards: the leverage that makes a small premium control a large position is exactly the feature that turns ordinary mistakes into large losses. A beginner should approach them the way they would approach borrowing to invest - possible, occasionally sensible, and dangerous by default.
A derivative is a contract whose value comes from something else - a share, an index, a currency, a commodity. The two families most investors meet are options and futures.
Instrument What the buyer gets What the seller takes on Call option the right to buy at the strike price by expiry the obligation to sell if asked Put option the right to sell at the strike price by expiry the obligation to buy if asked Future an obligation to buy or sell at a set price the matching obligation
An option buyer pays a premium up front and can never lose more than that premium. An option seller receives the premium and takes on an obligation that can cost far more. A futures position is an obligation on both sides, marked to market daily.
Listed equity options usually cover 100 shares per contract, so a quoted premium of 3 costs 300 per contract. Every option has an expiry date; after it the contract no longer exists. Nothing about the underlying company changes because you hold an option - you own no votes, no dividends and no claim on its assets.
Listed options and futures are cleared through a clearing house, which reduces counterparty risk. Over-the-counter derivatives, and many retail products such as contracts for difference, depend more directly on the firm on the other side.
Because the words are the product. A person who confuses buying a call with selling one has confused a limited loss with a potentially unlimited one. Most harm in this area starts with not knowing which side of the contract you are on.
The expiry date also changes the nature of being wrong. A shareholder who is early can wait. An option holder who is early can be right about direction and still lose everything, because the contract expired first.
And brokers usually require specific approval before allowing options or futures trading, because regulators treat these products as higher risk than ordinary shares.

Three positions on the same share, trading at 100.
Position Cash today Worst case Buy 100 shares pay 10,000 lose 10,000 if price goes to 0 Buy 1 call, strike 105, premium 3 pay 300 lose 300 Sell 1 call, strike 105, premium 3 receive 300 no fixed limit if price rises
The option buyer risks 300 to control exposure to 100 shares. The option seller collects 300 today and, if the share jumps to 150, must deliver shares worth 15,000 for 10,500 - a 4,500 obligation, less the 300 received, for a net loss of 4,200.
Assuming all option positions have limited risk because buying one does. Selling an option without owning the underlying, or trading futures, can create losses much larger than the cash you put up.
Before any trade, write whether you are buying or selling, and whether you hold a right or an obligation. If you cannot say, do not trade.
For bought options it is the premium. For sold options and futures, work out the loss at a large adverse move and treat it as possible.
Confirm how many units one contract covers and the exact expiry date, because both change the money at stake.
When you are trying to understand an options or futures product, a broker's approval questions, or a strategy someone is recommending.
Do not open any derivative position while any of these basics are unclear. For most investors, simply not using derivatives is the right decision.
Brokers typically assign options trading levels based on a self-reported questionnaire about experience and objectives. Regulators including FINRA have issued guidance and investor alerts about options risks and suitability, and have noted that retail options activity rose sharply in recent years, including very short-dated contracts.
Being approved to trade options says nothing about whether you understand them. Treat approval as permission, not as a judgement of readiness.
