I noticed one of my dividend stocks opened lower on the ex-dividend date by almost exactly what the dividend pays. It didn’t look like bad news or heavy selling — it just gapped down at the open. Is this a real drop I should worry about, and does it mean I can buy right before the ex-date, collect the dividend, and sell for a quick gain?

When a company pays a cash dividend, that cash leaves the business and goes to shareholders. Each share afterward represents a claim on slightly less cash than it did the day before. The ex-dividend date is the cutoff for who receives the payment: buy before it and you collect the dividend, buy on or after it and you do not. Because a new buyer on the ex-date is giving up that upcoming cash, the share is worth roughly one dividend less to them, and the stock opens lower to reflect it.
This adjustment is mechanical, not a wave of selling. Before the open on the ex-date, brokers and pricing feeds show an adjusted prior close, and exchanges reduce standing buy limit orders by the dividend amount. No one has to sell for the drop to appear; it is built into the opening price.
That is why dividend capture, buying just before the ex-date to grab the payout and then selling, is not free money. In theory the price decline offsets the dividend you receive, leaving total return roughly unchanged before costs. Commissions and the bid-ask spread, paid on both trades, chip away at it, and taxes often make it worse: a dividend captured over just a few days can fail the holding-period test for the lower qualified rate and be taxed as ordinary income.
In practice the drop is approximately, not exactly, the dividend, and ordinary daily price swings easily swamp it on any single stock.
