Recently, I noticed that many in the community still get confused about the basics of the market. I decided to understand what options are and share my understanding.

Simply put, an option is a contract that gives you the right (but not the obligation) to buy or sell an asset at a fixed price at a specific time. Sounds abstract? Here's a real example: imagine you like an apartment worth $200,000, but you don't have the money for three months. You negotiate with the owner, paying him $3,000 for the right to buy the apartment at that price later. If the house suddenly becomes worth $1 million (found something historic there), you exercise the option and make a $797,000 profit. If you find cracks and mold — you simply don't buy, losing only $3,000.

Here are the two main features: first, you have the right but no obligation. Second, the option's value depends on the underlying asset's price — it's a derivative instrument.

Now about the types. Call (option to buy) — you bet on the price rising. Put (option to sell) — on falling. There are four participants: call buyers, call sellers, put buyers, put sellers. Buyers are called holders, sellers are called writers. Holders can choose not to exercise their right, while writers are obliged to fulfill if the holder wants to.

To trade, you need to know key terms. Strike price — the price at which you can buy or sell. Expiration date — when everything ends. In the US, standard options on CBOE are called listed options — they have a fixed strike and date. One contract = 100 shares.

If for a call, the stock price is above the strike — the option is in-the-money, it has intrinsic value. The difference between the current price and the strike price is intrinsic value. The total cost of the option is called the premium. The premium is influenced by: the asset's price, strike, time to expiration, and volatility.

Why do people trade options? Two reasons: speculation and hedging. In speculation, you bet on price movement. A cool aspect — you're not limited to just upward movement. You can profit from falling prices and sideways movement. But the risk is high because you need to guess not only the direction but also the magnitude and timing of the move. The main advantage is leverage. One option controls 100 shares, so a small price increase can yield significant profit.

Hedging is like insurance. If you hold stocks but are worried, you can buy a put to protect your position. You lock in the maximum loss but keep the potential for growth.

Let's look at a practical example. A company's stock costs $67, a call option (strike $70, expiration in July) costs $3.15. The contract costs $315. Break-even point — $73.15 (70 + 3.15). If the price stays below $70, the option loses value, and you lose $315. If in three weeks the price jumps to $78, the option will be worth $825. Minus the $315 premium = $510 profit in three weeks. You can close the position and lock in profit or hold further. If the price drops to $62 by expiration, the contract becomes worthless.

According to CBOE data, only 10% of options are actually exercised. 60% are closed through trading (selling options on the market), 30% expire worthless.

The price of an option consists of two parts: intrinsic value (how much money the option is in-the-money) and time value (growth potential). Over time, time value decreases — this is called time decay. That's why options lose value even if the asset's price doesn't change.

There are two types of options: American (can be exercised at any time before expiration) and European (only on the expiration day). Most traded are American.

For long-term investors, there are LEAPS — options with a lifespan of several years. They work like regular options but with a longer horizon.

And there are exotic options — more complex structures with conditions like floating strike prices or knockout barriers. They are usually traded off-exchange.

When looking at a quote table: the option code includes the stock symbol, expiration month, strike, and type (C or P). Bid — the price the market maker buys at. Ask — the selling price. The spread can be an issue, especially for active traders. The time value shows how much of the premium is attributable to time. IV (implied volatility) — the expected volatility, influencing the option's price.

Delta shows how many points the option will change if the underlying asset moves by 1 point. Gamma — the rate of change of delta. Vega — sensitivity to volatility. Theta — time decay, how much the option loses each day. Volume and open interest indicate market activity.

In summary: what are options — a powerful tool for speculation and hedging, but requiring deep understanding. Not just a tool, but a whole system with its own logic and risks. If you're seriously interested in derivatives, it's worth spending time studying. On Gate, you can track prices and movements of the underlying assets that form the basis of options.
