Dividend capture: The actual mechanics and whether the math works—a realistic assessment
I've been running a dividend capture strategy for about three years alongside my long-term holdings. The results are mixed enough that I wanted to share an honest breakdown of how it works and when it doesn't.
The basic idea:
Buy a stock before the ex-dividend date, hold through that date to be entitled to the dividend, then sell once you've secured the payment. Rinse and repeat across many stocks. In theory, you're harvesting dividends without long-term capital commitment.
Why it seems like free money (it's not):
The textbook objection is that stocks drop by approximately the dividend amount on the ex-dividend date. Buy at £100, get a £2 dividend, stock opens at £98 on ex-day. You've netted zero minus transaction costs and taxes. Strategy debunked, right?
In practice, it's messier than that. Stock prices are affected by countless factors beyond dividend adjustments. The ex-day drop is often obscured by normal market volatility. Some stocks don't drop the full amount. Some drop more. The question becomes: can you systematically identify situations where the recovery happens quickly enough to make the capture profitable?
My actual approach:
I focus on stocks where:
The dividend is large enough to matter (at least 0.5% of share price per capture)
The stock is liquid enough to enter and exit without moving the price
Historical ex-day patterns suggest reasonable recovery times
There's no obvious reason to expect bad news around the ex-date
I typically hold for 1-5 days after the ex-date, waiting for the stock to recover some or all of the dividend drop. Sometimes I get lucky and it recovers same-day. Sometimes it takes a week. Sometimes it never recovers and I cut the loss.
The numbers after three years:
Total capture attempts: 247 Profitable (dividend + capital gain or minimal loss): 156 (63%) Breakeven-ish (dividend roughly offset loss): 41 (17%) Unprofitable (loss exceeded dividend): 50 (20%)
Net result: Positive, but only by about 2.3% annually on the capital deployed. That's before accounting for the significant time spent tracking ex-dates, placing orders, and managing positions.
The honest assessment:
Is dividend capture worth it? For me, it's been marginally profitable but probably not worth the effort relative to just holding quality dividend stocks long-term. The psychological overhead is also real—you're making dozens of trades, tracking many positions, and dealing with the emotional ups and downs of frequent winners and losers.
Where I think it can make sense: If you have capital sitting in a brokerage account that you don't want fully invested long-term (maybe you're waiting for better opportunities), capture can put that cash to work incrementally. The risk is you get caught holding a stock that drops hard.
Questions for the community:
What's your capture success rate?
Have you found specific sectors or stock types that work better for capture?
Does anyone run capture as their primary strategy vs. a supplement?
