When a dividend stock falls, its yield rises, so buying near the lows locks in a higher income stream. The risk is that the price is falling because the dividend is in danger, so check the payout ratio. This screen lists stocks on the London Stock Exchange with a dividend yield above 3% that trade within 10% of their 52-week low, highest yield first. LSE prices are quoted in pence, and the list skips thinly traded shares.
