Equity

Equity means a stake in a business rather than a loan to one. Returns come from the business growing and, sometimes, from dividends. There is no promised return and no maturity date, which is why equity swings far more than debt in the short run and has historically rewarded patience over long periods.

Owning versus lending

This is the core idea. When you buy equity, a share, you own a slice of the company and share in its fortunes: the value rises if the business does well and falls if it does badly. That is different from lending, say through a bond or a fixed deposit, where you are promised your money back with interest regardless of how the business performs. Ownership carries more risk and, historically, more reward.

Why it swings, and why time helps

Over days and months, share prices move on news, mood and expectations, so equity can rise or fall sharply. Over many years, prices tend to follow how the underlying businesses actually grow, which is why a long horizon has historically smoothed out the bumps. The flip side is simple: money you need within a few years does not belong in equity, because you cannot be sure where prices will be when you need it.

How most people own equity

Few beginners buy individual shares well. Most get equity exposure through an equity mutual fund or an index fund, which spreads your money across many companies at once, so one firm doing badly does not sink you. That spreading is diversification. Learn the groundwork in risk and return.
