tight spread
Tight Spread means the gap between the buying price and the selling price of a stock is small, so you lose very little just by getting in and out.
In plain English
"Why did I buy at ₦50.20 and sell at ₦50.00 and still barely lost anything?" Uche asked her cousin, staring at her trading app after a quick sell on a Lagos bank stock.
"Because that one has a tight spread," her cousin replied. "The buy price and sell price were sitting almost on top of each other. Some stocks are like that, small gap, small cost to move in and out."
That gap is the spread. The price someone is willing to buy at is called the bid, and the price someone is willing to sell at is called the ask. When those two numbers sit close together, traders call it a tight spread, and it usually happens with popular, heavily traded shares where lots of people are buying and selling every single day.
A wide spread is the opposite, and it costs you more just to get in and out, even before the share price itself moves. A small, thinly traded stock on the Nigerian Exchange might have a bid of ₦12.00 and an ask of ₦12.80, and that gap alone eats into your profit before the market even does anything.
For a Nigerian in Leeds trading Dangote Cement shares through an app, or a UK investor buying and selling Tesco shares on the London Stock Exchange, a tight spread means their money is not calmly leaking away through transaction friction. It is one small, often ignored sign that a stock is easy to trade without paying extra for the privilege.
MTN Nigeria shares might show a bid of ₦220.00 and an ask of ₦220.50. That fifty kobo gap is a tight spread, meaning you would only lose about ₦0.50 per share just from buying and immediately selling, compared to a smaller stock where that gap could be ₦2 or more.
Questions people ask
Why do some stocks have tighter spreads than others?
It mostly comes down to how actively a stock is traded. Popular shares with lots of daily buyers and sellers, like big bank or telecom stocks, tend to have tight spreads because there is always someone on the other side ready to trade. Smaller, less popular shares often have wider spreads because buyers and sellers are harder to match.
Does a tight spread mean a stock is a good investment?
Not on its own. A tight spread just tells you it is cheap and easy to trade in and out of, not that the company itself is doing well. You still need to look at the business, its earnings and its value before deciding if it deserves your money.
How can I check if a spread is tight before I buy?
Most trading apps and platforms show the current bid and ask price for a stock right next to each other. If they are close, say within a few kobo or a small percentage of the share price, the spread is tight. If there is a big gap, be aware that gap is a hidden cost.
