Options trading involves dealing in contracts whose value moves in line with an underlying asset such as a stock, index, or commodity. These contracts give the buyer the right, but not the obligation, to buy or sell the asset at an agreed price within a set timeframe. It’s a market built on flexibility and strategy, where knowing how options work is essential to using them effectively.
Options Contracts
An option is essentially a deal between two parties, where the buyer pays for the choice, not the obligation, to buy or sell an asset at a set price, called the strike price, within a specific time frame. Call options give the buyer the right to purchase the asset, while put options give them the right to sell it.
The cost of securing that choice is the premium, which goes to the seller for taking on the potential risk of being forced into a trade at the strike price. Premiums don’t come out of thin air, they’re shaped by the current market price, the strike price, how long is left before the option expires, and how wildly the underlying asset tends to move.
Example Options Trade
Let’s say you’re eyeing a company’s shares trading at $50. You think the price will climb, so you buy a call option with a strike price of $55. The premium is $2 per share, and since one contract covers 100 shares, it costs you $200 to open the position.
If the price shoots up to $70 before expiry, you can buy the shares for $55 and immediately have something worth $70. That’s a $15 gain per share. Knock off the $2 premium you paid, and you’re left with $13 profit per share. Multiply by 100 shares, and your total net gain is $1,300.
However, if the price stays below $55, exercising the option would make no sense – why buy at $55 when you can pick them up cheaper on the open market? In that case, the option expires worthless, and your only loss is the $200 premium.
The premium is therefore your starting cost and a key factor in working out whether an option is profitable. It’s not just about the strike price – the underlying market move has to cover the premium before you’re even breaking even.
Assets Traded Through Options
Options can be traded on a wide range of underlying assets. While they are most commonly associated with stocks, options can also be based on other assets such as:
Stock Indices: Options can be traded on stock indices like the FTSE 100 or the S&P 500. These options give traders the right to buy or sell a basket of stocks that make up the index, allowing for speculation or hedging on broader market movements.
Commodities: Options are available on commodities such as gold, oil, and agricultural products. For example, an option on crude oil might give the holder the right to buy or sell oil futures at a specific price before a certain date.
Currencies: Currency options allow traders to speculate on or hedge against changes in exchange rates between currencies. For instance, an option might provide the right to exchange euros for US dollars at a predetermined rate.
Interest Rates: Options can also be based on interest rates, such as options on Treasury bonds or interest rate futures. These options allow traders to speculate on or hedge against changes in interest rates.
Exchange-Traded Funds (ETFs): ETFs, which are investment funds traded on stock exchanges, can also have options. These options allow traders to gain exposure to a diversified portfolio of assets.
Advantages of Trading Options
Options can be structured to profit in rising, falling, or even flat markets, giving traders more strategies to work with than simply buying or selling the underlying asset.
Options can act as a form of insurance, allowing investors to hedge against losses in other positions. For example, buying put options can offset potential declines in a stock portfolio.
Disadvantages of Trading Options
For buyers, if the market fails to move as expected before expiry, the option can expire worthless, resulting in a total loss of the premium paid.
Selling options without holding the underlying asset, known as naked writing, can expose traders to theoretically unlimited losses if the market moves sharply against them.
Frequently Asked Questions
Still have questions about Options Trading? Here are some quick answers to the most common ones.
Why sell an option below the market price of the asset?
Traders might sell options below the market price to execute specific strategies, manage risk, or generate income from premiums. If they believe the asset won’t reach the strike price, they can profit from the option expiring worthless, often as part of a broader hedging or portfolio adjustment plan.
How does the premium impact a trader’s decision?
The premium represents the cost for buyers and income for sellers. Buyers risk losing the premium if the option expires worthless, while sellers earn income but risk losses if the asset’s price moves unfavourably.
Why use options despite the risks?
Options offer hedging, leveraged speculation, and income generation, providing flexibility to profit in various market conditions. Though they carry risk, they allow traders to manage exposure and capital efficiently.
