Pretty much everyone with investing experience knows how to buy shares of a stock—it’s one of the first things we learn to do as investors. Armed with a brokerage account, you can become part owner of a publicly traded company simply by purchasing shares directly through an exchange.
Suppose you’ve identified an attractive company that you believe has a bright future. You might purchase 100 shares at a price you feel is attractive, say $50 per share. So you’d put up $5,000, plus commission and any other transaction costs, to purchase 100 shares.
Key Points
- Call options give the buyer the right, but not the obligation, to buy an underlying asset at a specific price within a certain time frame.
- Put options give the buyer the right to sell the underlying asset at a specific price within a certain time frame.
- Option prices are affected by factors such as strike price, time to expiration, interest rates, and volatility.
For every dollar the share price rises, you make $100. For every dollar it falls, you lose $100. If the share price doubles, you double your money. If the company goes bankrupt, you lose the entire $5,000.
But what if you could control those same 100 shares with only a fraction of the capital and limit your maximum risk in case something catastrophic happens? Welcome to the world of options. If it sounds too good to be true, just know that—as with anything in investing and trading—there are caveats.
What are call and put options?
So exactly how can you get exposure to the upside potential of a stock, but with less up-front capital outlay and with a limit to the downside risk? By purchasing a call option contract.
A call option gives the buyer the right—but not the obligation—to purchase shares of the underlying stock at a set price (called the strike price or exercise price) by a set date (called the expiration date). For this right you pay a premium, which is the price of the option contract and, for a long call option, is also the maximum risk in the trade.
But what if you think the stock is set for a sell-off rather than a rally? You could buy a put option. This gives you the right, but not the obligation, to sell the underlying stock at the strike price on or before the expiration date. You pay a premium, which again represents your maximum risk.
Everyday life is full of options
Even if you have no experience with options, they may be part of your life already. Have you ever used a discount coupon at the grocery store? Suppose you have a coupon for a box of Cheerios for $3 that expires in 60 days. That coupon gives you the right, but not the obligation, to buy a box of Cheerios for $3. In other words, it’s a call option.
If you can’t find a box of Cheerios anywhere for less than $5, you’ll use your coupon. If the store down the road puts all Cheerios on sale for $2.50, you’ll throw your coupon in the garbage.
In contrast, when you buy car insurance—mandatory in the U.S.—you own a put option on your car. Your insurance policy gives you the right to put a dollar claim to the insurance company should your car be damaged while the policy is in force. For this right you pay a premium to the insurance company.
Look around and you’ll see plenty of embedded options in the form of coupons, insurance, warranties, store exchange policies, trade-in policies, and other commercial transactions.
Components of option contracts
There are four major components of call and put contracts:
- The multiplier. For stocks (or “equities,” as the pros call them), standard option contracts are deliverable into 100 shares. So if you have one option, you control 100 shares.
- The strike price. This is the price where you have the right, but not the obligation, to buy the stock (with a call option), or sell the stock (if you’ve purchased a put option).
- The premium (or price of the contract). Each contract has an associated price or premium, which is what you pay to buy a call or put. You can also sell (or “write”) options contracts, in which case you’re paid the premium, but if the buyer chooses to exercise the option, you have the obligation to make good on the contract.
- Time. All option contracts have an expiration date (“expiry” in industry lingo). The more time is left before an option expires, all else being equal, the more expensive the option.
A note on dividends
Don’t forget about dividends. When a company pays a dividend, it goes to the owner of record as of the so-called ex-dividend date. Owning a call option does not entitle you to dividends. In general, call options that expire just after an ex-dividend date are less valuable to account for the difference. It’s something you should be aware of when considering buying stock versus call options.
A call option example
Suppose you’re liking company XYZ’s prospects. Let’s say the stock has sold off over the last few months, but your analysis indicates a rally may be in store. The stock is currently trading at $145. You decide to look at call options that expire three months in the future with a strike price of $150.
- Call strike: $150
- Expiration: 90 days
- Price (premium): $3, which is $300 per contract. (This is also your max risk.)
- Breakeven at expiration: $153 ($150 strike price + $3). You need the underlying stock to rise beyond $153 in order to make a profit.
For the next three months, you have the right to buy 100 shares of XYZ at $150 per share. You paid $300 for that right. If the stock rallies above $150, the option’s value will begin to offset that cost. If it rises to $153, the position breaks even; if it goes any higher, you’ll be in the profit zone. On the other hand, if the stock doesn’t rise the way you expect, or even if it falls precipitously, you’ll only lose the original $300 premium.
In contrast, if you bought 100 shares of stock at $145, it would have cost you $14,500 up front. Although you would profit, dollar-for-dollar, if the stock rises, you would also lose, dollar-for-dollar, if your analysis is wrong and the stock keeps falling.
Note that you don’t have to hold the call option all the way to expiration. You can choose to sell the contract anytime you want. For most stocks—and all actively traded stocks—there’s a robust market full of professional traders and market makers posting competitive bids and offers throughout each trading day.
The bottom line
Pros cite three main reasons for choosing to trade options:
- Flexibility. Options let you speculate on the direction of the underlying stock—up or down—and some option strategies are even designed to profit in a sideways market.
- Defined risk. If you wish to put a cap on your risk—or at least know the math up front—many option strategies, such as buying calls and puts, or selling certain option spreads, allow you to know the risk (and probabilities) before you hit the button.
- Capital efficiency. Options let you utilize leverage (but with defined risk) to potentially boost your returns.
These two basic option strategies—buying call options to speculate on a stock going up, and buying put options to speculate on a stock going down—really just scratch the surface of all that’s possible with options. And they’re not just for stocks—there are options listed on exchange-traded funds, indexes, futures contracts, and more. There are even option-selling strategies that aim to generate income.
The more you learn about the options market, the more you’ll understand the allure. But they’re not for everyone. Nor are options a set-it-and-forget-it investment. The first step is education.
