I’ve been thinking for a long time about whether I should get involved with options until I realized one thing: they are not just a financial instrument, they are essentially insurance for your portfolio. Let me explain why options deserve the attention of every investor.

An option is essentially a contract that gives you the right (but not the obligation) to buy or sell an asset at a predetermined price on a specific day or earlier. Sounds complicated? Imagine this scenario: you find the perfect apartment, but you only have the money in three months. You negotiate with the owner, pay him $3,000, and he promises to sell you the property for $200,000 within three months. That’s an option.

Now, two possible outcomes. First: after a month, it turns out that this is Elvis Presley’s birthplace, and the price skyrockets to a million. Since you bought an option to purchase real estate (say), the seller is obliged to sell to you at $200,000. Your profit is $797,000. Second: you discover cracks in the walls, mice, and other problems. Thanks to the option, you can simply cancel the deal, losing only the $3,000 premium.

This is the key point: if you buy a stock call option, you gain flexibility. You are not obligated to do anything. The option can expire worthless, and you will only lose the premium.

There are two main types. A call option gives the right to buy an asset at a fixed price, for optimists. A put option gives the right to sell, for pessimists. If you bought a call option for IBM stock at $70, and it’s trading at $67, you need the price to rise above $73.15 (70 plus a $3.15 premium) to be profitable.

There are four types of market participants: those who buy calls, those who sell them, those who buy puts, and those who sell them. Buyers are called holders, sellers are writers. Holders have long positions, writers have short positions.

Why do people use options? Two reasons: speculation and hedging. With speculation, it’s clear: you bet on price movement. But the main advantage here is leverage. One option controls 100 shares. If the price rises by 10%, your profit can be several times larger.

Hedging is insurance. If you bought a call option on stocks but want to protect yourself from a decline, you simultaneously buy a put. This allows you to catch the upside while limiting losses.

Now, practice. Imagine, on May 1, the stock of company A is $67. A July call option with a strike price of $70 costs $3.15. The contract covers 100 shares, so you pay $315. After three weeks, the price jumps to $78. Now, the option is worth $8.25. Your profit is $5.10 over three weeks. You can close the position (sell the option) and lock in your profit. Or hold on if you believe in further growth.

A significant portion of options are never exercised. According to CBOE data, only 10% are exercised, 60% are closed through trading, and 30% expire worthless.

The price of an option consists of two parts: intrinsic value and time value. Intrinsic value is the profit you would get right now. Time value is the potential for the option to increase in value. As the expiration date approaches, the time value decreases (this is called time decay).

There are American options (can be exercised at any time) and European options (only on the expiration day). There are also long-term options (LEAPS) with a 1-2 year term, suitable for long positions.

When reading a quote table, pay attention to several parameters. Delta shows how the option moves with the stock. A delta of 50 means the option increases by 0.5 points when the stock rises by 1 point. Gamma shows how delta changes. Vega indicates sensitivity to volatility. Theta shows how much the option’s value loses each day.

An important point: volatility is critical. If you buy a call option on stocks during low volatility, an increase in future volatility works in your favor. If volatility is high, it’s better to sell options rather than buy.

In practice, most traders do not exercise options but trade them as standalone instruments. This provides more flexibility and allows profit extraction at different stages of price movement.

Options are a powerful tool but require understanding. If you buy a call option on stocks, remember: you control a large volume of the asset with a small capital. This means high potential profit but also a high risk of losing the entire premium.
