Let's figure out what options really are because they are one of the most confusing yet powerful tools in the market.

Options are contracts that give you the right (but not the obligation!) to buy or sell an asset at a predetermined price at a specific point in time. Sounds complicated? Let's look at a simple example. Imagine you've found a great apartment, but you don't have enough money for three more months. You agree with the owner: he gives you the right to buy the apartment for 200 thousand within three months, and you pay him 3 thousand for this right. That is an option in real life.

Now, two scenarios. In the first case, it turns out that this is a historic site, and the apartment's price suddenly jumps to a million. You exercise your right, buy the apartment for the agreed 200 thousand, and sell it for a million. Profit is about 797 thousand minus your 3 thousand for the right. Excellent!

In the second scenario, you discover that the apartment is full of cracks, mice in the pantry, a complete nightmare. But here’s the catch: you are not obligated to buy it. You just lose the 3 thousand you paid for the right. That’s all.

Here are two main points: first, if you buy an option, it’s your right, not an obligation. Second, options are derivatives, tied to some underlying asset. In the market, this is usually stocks or indices.

There are two main types. A call option gives the right to buy the asset. If you believe the price will go up, you buy a call. A put option gives the right to sell. If you expect the price to fall, a put is your choice. The logic is simple: with a call, you profit from rising prices; with a put, from falling prices.

In the options market, there are four types of participants: those who buy calls, those who sell calls, those who buy puts, and those who sell puts. Buyers are called holders, sellers are called writers. Holders have long positions, writers have short positions. The main difference: holders are not obliged to do anything, while writers must fulfill their obligations if the holder wants to exercise the right.

Now, a few terms you need to know. The strike price is the price at which you can buy or sell the asset. The expiration date is the last day you can use the option. On American exchanges like CBOE, listed options with fixed strike prices and expiration dates are quoted. Each contract is the right to 100 shares.

If for a call option, the stock price is above the strike price, the option is considered in the money. The difference between them is the intrinsic value. The total value of the option is called the premium, and it depends on the stock price, strike price, time to expiration, and volatility.

Why do people use options at all? Two main reasons: speculation and hedging. With speculation, you bet on price movement. The fun of options is that you can profit not only from rising but also from falling, and even when the market moves sideways. The risk is higher, but so is the potential. The main advantage is leverage. One option controls 100 shares, so a small price movement can give you a substantial profit.

Hedging is insurance for your investments. Like home insurance, options protect you from losses. You can control the risk of falling prices at a low level while catching all the upside.

Let's look at a specific example. Suppose a stock costs $67, and a call option with a strike price of $70 and three months to expiration costs $3.15. The total contract price is $315 (3.15 multiplied by 100). To make a profit, the price must rise above $73.15 ($70 plus $3.15 premium). In three weeks, the price jumps to $78, and the option is now worth $825. Minus $315 for the premium, your profit is $510. In three weeks, you nearly doubled your money!

You can close the position and lock in the profit by selling the option. Or wait if you believe the price will continue to rise. But if the price drops below 70 by the expiration date, the option becomes worthless, and you lose the entire $315 premium.

According to CBOE data, in reality, only about 10 percent of options are actually exercised. 60 percent are closed through trading, and 30 percent simply expire worthless.

The price of an option consists of two parts: intrinsic value and time value. Intrinsic is the amount by which the option is already in the money. Time value is the potential for the option to increase in price. As the expiration date approaches, the time value decreases, called time decay.

There are two types of options based on exercise style. American options can be exercised at any time before expiration. European options can only be exercised on the expiration day. This is not about geography, just names.

For long-term investors, there are LEAPS options with a term of a year, two, or sometimes more. They differ from regular options only in duration.

Besides standard options, there are exotic options with non-standard conditions. For example, the strike price may depend on the average price over a period, or the option may be canceled if the asset price exceeds a certain level.

When you look at options quotes, there’s a lot of information. The option code includes the stock symbol, month, year, strike price, and type (C for call, P for put). The bid price is the last price at which a market maker is willing to buy. The ask price is the price at which they are willing to sell. The difference is the spread, and the wider the spread, the harder it is to trade.

Time value shows how much premium is potential, not actual value. Volatility indicates the expected future movement of the price. The higher the volatility, the more expensive the option.

Next come the Greeks. Delta shows how much the option’s price will change with a one-point move in the stock. Gamma shows how delta itself changes. Vega indicates the impact of volatility on the price. Theta shows how much value the option loses each day due to time decay. Volume indicates how many contracts were traded. Open interest shows how many contracts are open and not closed.

That’s what options really are. A powerful tool, but it requires understanding. Use them wisely.
