A share is a small, tradeable piece of ownership in a real company. Buy one share of a listed company, and you own a tiny fraction of that company itself: its operations, its profits, its future, split into millions of identical pieces so that ordinary people can own a slice without buying the whole thing.
Two things can happen to that piece of ownership. The company can pay you a portion of its profit directly, called a dividend, usually once or twice a year. Or the share itself can become worth more, or less, as the market's opinion of the company changes, which you only realise as a gain or a loss if you sell.
This is different from a mutual fund, which is a basket of many shares, and sometimes bonds, managed for you. A single share is a bet on one company. A fund is a bet on a basket, chosen and rebalanced by someone else, so no single company's disaster sinks your entire position.
Neither is automatically the right answer. The useful habit, from the very first naira you invest, is knowing which one you are holding, and why.
