What Are Stocks? Calls and Puts.

One of the most common words people think of when finance comes to mind is stocks. Although stocks frequently appear in movies and memes, many people still don’t fully understand what they actually are. At its core, a stock represents equity, meaning a small piece of ownership in a company. When a company wants to grow, it can divide its ownership into millions of shares by going public. When you buy a share, you become a shareholder, which means you have a legal claim to a portion of the company’s assets and earnings.

There are two main ways to profit from stocks:

Appreciation – when the company’s value increases, and the stock price rises

Dividends – periodic payments distributed to shareholders

Like all investments, stocks come with both upsides and risks. In theory, a stock has unlimited upside since its value can continue to rise. However, the downside risk can be as much as the total amount you invested. Now that we understand stocks as a form of ownership, we can move on to options, which involve contracts and time.

Options

An option is a contract that gives the buyer the right, but not the obligation, to buy or sell a stock at a specific price, called the strike price, before a set expiration date. Options can seem intimidating at first, so it can help to think of them as a “reservation.” You pay a small fee (called the premium) to lock in a price today, regardless of what happens in the market tomorrow.

To understand options, you need to know three key concepts:

Strike Price: The price at which you agree to buy or sell the stock

Expiration Date: The deadline after which the option becomes worthless

Premium: The upfront cost of the contract, which is also the maximum amount you can lose as a buyer

Options are used for several reasons. They can provide leverage, allowing you to control shares for a fraction of the cost of buying them outright. They are also commonly used for hedging, such as buying puts to protect a portfolio from market downturns.

The “Call”

A call option represents a bullish outlook, meaning you expect the stock price to rise. If the stock price increases, your profit is the difference between the stock price and the strike price, minus the premium you paid.  If you buy a call option on Tesla with a strike price of $100 and a $2 premium, and the stock rises to $110, you can exercise your option and earn: $110 − $100 − $2 = $8 profit However, if the stock price falls to $90, you would simply let the option expire and only lose the premium of $2. On the other hand, selling (or writing) calls means collecting the premium while taking on the obligation to sell shares if the buyer exercises the option. Investors often use this strategy to generate additional income. Now that we understand call options, let’s look at put options.

The “Put”

A put option gives the buyer the right to sell shares at a specific price before expiration. When you buy a put, you are bearish; you expect the stock price to fall. The advantage of a put option is that it allows you to sell shares at the strike price, even if the market price drops below it. If a stock is trading at $100 and you buy a put with a $90 strike price and a $2 premium, and the stock falls to $80, you can still sell it at $90. Your profit would be: $90 − $80 − $2 = $8. If the stock price rises instead, you would let the option expire and only lose the premium. Investors often use puts when they believe a company is overvalued. Buying puts is also a way to short the market while keeping risk limited to the premium paid.

Comparing Stocks and Options

Although options are based on stocks, they are fundamentally different from simply buying shares. Stocks give you direct ownership in a company, while options give you ownership of a contract related to that stock. Stocks can be held indefinitely, while options always have an expiration date. Additionally, buying stocks requires paying the full share price, whereas buying options requires paying only the premium. Risk also differs between the two. With stocks, losses depend on how much the price falls. With options, the premium represents most (or all) of the risk for buyers, but that value can be lost quickly.

Final Thoughts

With all this information, you might wonder: why not always use options instead of stocks? In reality, options involve time decay, meaning the contract loses value as time passes if the stock doesn’t move in your favour. This ties into the concept of the time value of money: a dollar today is worth more than a dollar tomorrow due to factors such as inflation and opportunity cost. In summary, stocks are generally used for long-term investing and wealth building. Options are commonly used for hedging, generating income, or short-term speculation.
