The dividend a stock pays now, measured against what you originally paid for it rather than against today's price. Hold a company that keeps raising its dividend and this figure climbs even as the quoted yield stays flat, which is the whole appeal of dividend growth investing. It says nothing about whether the stock is worth buying today: for that, the current yield is the only relevant one. PSEye's portfolio page reports your income against current market value, so work out yield on cost from the cost basis it shows you.
