call option
Call Option: the right, but not the obligation, to buy a stock at an agreed price before a set date, useful when you expect the price to rise.
In plain English
A lot of people who dabble in shares make the same calm mistake. They watch a stock they cannot afford to buy in bulk, sigh, and walk away, thinking the only way to profit from a rise is to own the shares outright.
A call option offers a smaller door into that same trade. It is a contract that gives you the right to buy a stock at a fixed price, called the strike price, before a certain date, without forcing you to actually do it if the price does not move your way.
Say a Nigerian investor tracking a bank stock on the Nigerian Exchange notices it trading at ₦25 and believes good results will push it higher. Instead of tying up a large sum buying shares directly, they pay a smaller fee, called a premium, for a call option that lets them buy at ₦28 within the next two months.
If the share price climbs to ₦35, they can exercise the option, buy at ₦28, and either hold the shares or sell immediately for a profit. If the price stays below ₦28, they simply let the option expire and lose only the premium, not a fortune.
In the United Kingdom, the same idea plays out on shares listed on the London Stock Exchange, where traders use call options to bet on a rise in companies like Tesco or BP without committing the full share price upfront.
For someone abroad sending money home to invest, understanding call options matters because they explain why some relatives talk about controlling shares worth millions with a fraction of the cash, and why that comes with its own real risk of losing the premium entirely.
An investor buys a call option on a stock at a strike price of ₦28 for a premium of ₦1,000. The stock rises to ₦35, so they exercise the option, buy at ₦28, and sell at ₦35, making ₦7,000 minus the ₦1,000 premium, for a net gain of ₦6,000.
Questions people ask
What happens if the stock price never reaches my strike price?
Nothing dramatic happens to your finances beyond the premium you already paid. The option simply expires worthless, and your loss is limited to that premium, never more.
Can I sell a call option instead of exercising it?
Yes, in markets where options trade actively, you can sell the option itself before expiry if its value has risen, often making a profit without ever buying the underlying shares.
Are call options available on Nigerian stocks?
Formal options trading is still limited on the Nigerian Exchange compared to markets like the London Stock Exchange or New York Stock Exchange, so many Nigerian investors learn the concept through global platforms or foreign brokers first.
