If I had to teach this in one paragraph, I would start here: a high dividend yield is sometimes a warning sign, not a gift. Core idea: Yield rises when the price falls. If the price is falling because the business is deteriorating, the dividend may be the next thing to go. Why it matters: That distinction separates income investing from a value trap disguised as yield. In real life: A utility yielding 8% when peers yield 4% often means the market is pricing in a dividend cut, not rewarding patient investors. Common slip: The mistake is screening only by yield level without checking payout ratio, free cash flow coverage and debt trends. Try this: If you had to teach this without jargon, what would you tell someone to monitor first? A lot of confusion disappears once you separate the headline from the mechanism.
