Dividends are payments of a portion of a company's earnings to its shareholders. When a company generates profits, it has the option to reinvest those profits back into the business or distribute a portion to investors as dividends.

For shareholders, dividends represent a source of investment income. Many investors prefer owning stocks that pay dividends because it provides a steady stream of returns in addition to any gains from stock price appreciation.

Dividends are typically paid out as cash, but companies can also issue stock dividends by distributing additional shares to investors instead of cash.

While dividends provide income, it's important for investors to consider them in the context of total return: share price gains plus dividend payments. Some companies prioritize paying higher dividends at the expense of reinvesting back into the business for growth.

Dividend payments should ideally come from a company's profits and free cash flow. Unsustainable dividends funded by debt can be a red flag. Evaluate the company's dividend payout ratio - the percentage of net income going to dividends - to assess dividend sustainability.

Look for companies with a consistent, growing dividend over time. Rising dividends protect your future income stream against inflation erosion.

Beyond providing income, dividends can signal a company's financial health and maturity. Mature, profit-generating companies are more likely to pay dividends than growth-focused startups which prefer reinvesting.

For long-term investors, the power of compounding can turn even modest dividend reinvestment into a major portfolio driver over decades. This makes dividends particularly valuable for retirees seeking income.
