What are options?

Options trading can seem impenetrable for beginners at first glance. The terminology feels foreign, the mechanics appear complicated and the risks may seem unclear. Yet options are simply financial contracts with defined rules, and understanding those rules is entirely achievable with patient study.

An option is a financial contract that gives you the right, but not the obligation, to buy or sell an underlying asset at a predetermined price before or on a specific date. The underlying asset might be shares, an index, a currency pair or a commodity.

The crucial distinction between options and ordinary share ownership is this: when you buy shares, you own part of a company outright. When you buy an option, you own only the right to transact at certain terms. You pay a fee upfront for this right, called the premium, and that premium (plus any dealing/FX fees) is the maximum you can lose if you let the option expire.

Think of it like paying a small deposit to reserve a house at today’s price for the next three months. If house prices rise, you can complete the purchase at the lower reserved price. If prices fall, you walk away and lose only the deposit. The deposit bought you flexibility, not ownership.

Calls and puts explained

Options come in two varieties: calls and puts.

A call option gives you the right to buy the underlying asset at a specified price. You might purchase a call if you expect the price of the underlying to rise. If the price does increase above your specified level, you can exercise your right to buy at the lower price or sell the option itself for a profit.

A put option gives you the right to sell the underlying asset at a specified price. You might purchase a put if you expect the price to fall. If it does drop below your specified level, you can exercise your right to sell at the higher price, or sell the option for a profit.

Key terminology you need to know

Before trading options, you need to understand several terms that appear constantly.

The underlying asset is whatever the option contract relates to. For equity options, this is typically shares in a company or units in an exchange-traded fund.

The strike price is the predetermined price at which you can buy or sell the underlying if you exercise the option.

The expiry date is when the option contract ends. After this date, the option ceases to exist. European-style options can only be exercised on the expiry date itself, while American-style options can be exercised at any point up to and including expiration day.

The premium is the price you pay to purchase the option. This cost is non-refundable regardless of whether you exercise the option.

An option is in the money (ITM) when exercising it would be profitable before accounting for the premium paid. A call is ITM when the underlying price exceeds the strike price. A put is ITM when the underlying price sits below the strike.

An option is out of the money (OTM) when exercising it would not be profitable. A call is OTM when the underlying price is below the strike. A put is OTM when the underlying price is above the strike.

How options trading works

Understanding the mechanics of options trading requires grasping how strike price, expiry and premium interact, and knowing the difference between exercising an option and selling it.

Strike price, expiry and premium

These three elements determine an option’s value and behaviour.

The strike price sets your transaction level. If you hold a call option with a strike price of 100 pence on a share currently trading at 110 pence, your option is ITM by 10p. If the share trades at 90p, your call is OTM.

The expiry date creates urgency. An option with six months until expiry has more time for the underlying to move favourably than one expiring next week. More time generally means a higher premium.

The premium reflects what the market believes the option is worth. It comprises two components: intrinsic value and time value. Intrinsic value is how much the option is ITM. Time value is the additional amount the market pays for the possibility that the option could become more valuable before expiry.

Exercising vs selling an option

When you own an option that has value, you have two choices: exercise it or sell it.

Exercising means using your right under the contract. If you exercise a call option, you buy the underlying at the strike price. If you exercise a put, you sell the underlying at the strike price. To exercise a call, you need sufficient funds to purchase the shares. To exercise a put, you typically need to own the shares.

Selling the option means transferring your rights to another market participant. You receive cash equal to the option’s market value. Many traders prefer selling because it captures both intrinsic and remaining time value without requiring the capital to buy or own the underlying shares.

Most options are sold rather than exercised. This is particularly common among retail traders who are speculating on price movements rather than seeking to acquire or dispose of the underlying asset.

Why do people trade options?

Traders and investors use options for two primary purposes: hedging existing positions and speculating on price movements. Both carry risks, and neither guarantees profits.

Hedging existing positions

If you own shares and worry about a short-term price decline, you might purchase put options as a form of insurance. Should the share price fall, the put options increase in value, partially offsetting losses in your share holdings.

This hedging has a cost: the premium you pay for the put options. If the share price rises or stays flat, you keep your shares and their gains, but you lose the premium paid for protection. Hedging reduces risk but also reduces potential returns by the cost of the protection.

Institutional investors frequently use options to manage portfolio risk. Retail investors may also hedge, though the costs can be proportionally higher for smaller positions.

Speculating on price movements

Some traders buy options purely to profit from anticipated price movements without owning the underlying asset. This is speculation, and it carries substantial risks.

Options offer leverage in the sense that a small premium controls exposure to a larger position. If your view proves correct, percentage returns on the premium can be substantial. If your view proves wrong, you can lose your entire premium.

Trading stock options for beginners often focuses on this speculative use, but it is worth understanding that many options go both unsold and unexercised. According to the Chicago Board Options Exchange, 30-35% of contracts expire worthless. The buyer loses their premium in such cases. Options speculation requires not just a correct view on direction, but also timing and magnitude of the move.

Understanding the risks of options trading

Options are complex instruments, and the risks are real. Before trading options, beginners and experienced traders alike would do well to understand these risks.

Time decay and volatility

Time decay, also called theta, describes how an option loses value as expiry approaches. All else being equal, an option is worth less today than it was yesterday because there is less time for the underlying to move favourably.

This decay accelerates as expiry nears. An option with 60 days remaining might lose 1p per day in time value. With 10 days remaining, it might lose 3p per day. With 2 days remaining, decay can be severe.

These are hypothetical figures; the value of shorter-term options also decays faster than longer-term contracts’ value (all else being equal), and the rate of their value decay speeds up as they get closer to expiration.

Volatility affects option prices significantly. Higher expected volatility increases premiums because larger price swings make profitable outcomes more likely. If volatility falls after you purchase an option, the option’s value may decline even if the underlying price moves in your favour.

Both factors mean that being right about direction is insufficient. You must also be right about timing and the market’s volatility expectations.

Potential for total loss of premium

When you buy an option, the maximum you can lose is the premium paid. This may sound reassuring, but consider what it means: you can lose 100% of your investment in that position.

If you buy a call option and the underlying price stays below the strike until expiry, your option expires worthless. You lose everything you paid. The same applies to puts if the underlying stays above the strike.

Unlike shares, where a company must go bankrupt for your investment to reach zero, an option can become worthless simply because the price did not move enough, or did not move quickly enough, in your anticipated direction.

This potential for total loss makes position sizing crucial. Risking more than you can afford to lose on options positions can result in significant harm to your finances.

How to get started with options in the UK

If you have read this far and still wish to explore options trading, here are the practical steps to begin.

Choosing a regulated broker

If you trade options with a UK firm, ensure the broker is authorised and regulated by the Financial Conduct Authority (FCA). If you use a non-UK/non-FCA firm, you may not have the same UK regulatory protections. FCA regulation provides certain protections, including requirements around how firms treat client money and how they communicate risks.

Regulation does not protect you from trading losses, and the availability of protections (eg FSCS) depends on the firm and product.

Not all brokers offer options trading. Those that do often require you to complete suitability questionnaires or assessments before granting access. This is a regulatory requirement designed to ensure you understand the risks involved.

When comparing brokers, consider:

• Whether they offer the specific options markets you wish to trade

• Commission structures and any minimum account requirements

• The quality of their educational resources

• Platform usability and tools for analysing options

Do not choose a broker based solely on low costs. Reliability, regulation and educational support matter, especially when trading options for beginners.

What you need before placing your first trade

Before executing your first trade, ensure you have addressed the following:

• Education: Understand what you are buying, why you are buying it and what could go wrong. If you cannot explain the trade to someone else, you are not ready.

• An approved account: Open and fund an account with an FCA-regulated broker that permits options trading. Complete any required assessments honestly.

• Capital you can afford to lose: Only use money that, if lost entirely, would not affect your ability to meet financial obligations. Options trading beginners sometimes underestimate how quickly capital can disappear.

• A clear plan: Know your entry criteria, your maximum acceptable loss and the conditions under which you would close the position. Write these down before trading.

• Emotional preparation: Accept that losses are part of trading. If losing your premium would cause significant distress, reconsider whether options trading suits your circumstances.

There is no rush. The options markets will exist tomorrow, next week and next year. Taking time to learn properly costs nothing. Trading before you are ready can cost everything you commit.

Summary

Options are financial contracts providing the right to buy or sell an underlying asset at a predetermined price before expiry. Calls give the right to buy; puts give the right to sell. The premium you pay is the maximum loss when buying options, but that loss can be total.

Traders use options for hedging and speculation, each carrying its own risk profile. Time decay erodes option value as expiry approaches, and volatility changes can affect prices regardless of the underlying’s direction.

To begin trading options in the UK, you need an FCA-regulated broker, a clear understanding of the mechanics and risks, capital you can afford to lose and a written plan for each trade. Options may not be suitable for all investors, and thorough education should precede any trading activity.

Remember: your capital is at risk. Complex instruments like options require respect, patience and continuous learning.
