Stocks and Dividends

Imagine you pool your money with three or four friends to start a taco truck. You need 1 million won (about $750) in total, and you chip in 200,000 won (about $150). That makes you the owner of 20% of the business. The imaginary slip of paper that proves your share is a stock. A person who holds stock is called a shareholder.

Say the truck goes viral and business booms. Two good things can happen.

First, people expect the truck to keep making money, so more of them want to buy your 20% stake, and its price goes up. You can sell your slip to someone else at a higher price and keep the difference.

Second, you can split the profit that's left after running the truck each month, according to your share. Suppose 1 million won is left after paying for ingredients and electricity. Your 20% means 200,000 won lands in your bank account. But there's a catch: the owners get together and decide whether to split the leftover money or put it back into the business. Making a profit doesn't mean it automatically gets paid out.

A real company works just like the taco truck. It spends the year making and selling products, and the net profit left over can be paid out to shareholders on a regular schedule. That payout is called a dividend. Even if you own just one share, you're an owner, so as long as it's the same type of stock (common with common, preferred with preferred), you have the right to the same dividend per share as everyone else.

Large, steady companies like big manufacturers, banks, and telecom firms often pay solid dividends every year or every quarter. That's why investors nearing retirement, or anyone who wants steady cash flow, tend to like high-dividend stocks.

But not every company pays dividends. A young tech company that's just getting started and growing fast usually does better by putting its money to work. Instead of handing cash to shareholders, it will reinvest in new factories and technology, which does much more to help the company grow.

A big dividend doesn't automatically make a stock the best investment. If a company pays out all the money it earns instead of spending any on future growth, its engine for growth can stall, and its stock price may fall over the long run.

There's another catch. On the day the right to the dividend disappears (in Korea, usually the trading day right before the record date), the stock price tends to drop by roughly the amount of the dividend. This is called the ex-dividend drop. The market is pricing in the fact that the company is about to send that cash out of its vault, so the company is worth that much less. In the end, a dividend isn't free money falling from the sky. It's a piece of the company's value being handed to you early, in cash.

So smart investors don't look only at the dividend yield number. They also check whether the company earns solid profits while paying dividends, and whether it's still building future strength with the money left over after paying shareholders.
