NEW YORK (TheStreet) -- Seeking income, investors have poured into dividend exchange-traded funds. Lately the move has proved rewarding.During the past three years, PowerShares Dividend Achievers ( PFM) has returned 12.5% annually, outdoing the S&P 500 by a percentage point, according to Morningstar.

During the past three years, PowerShares Buyback Achievers ( PKW) returned 15.1% annually. The outlook for the buyback fund remains bright. While sales of S&P 500 companies are growing at an annual rate of 1.8%, the stocks in the buyback fund are growing 9.2%.

Nygren looks for unloved companies that are increasing the value of their businesses. Over the years he has often favored dividend payers and companies that are repurchasing shares. He likes such stocks because they have strong cash flows and are using the money to enrich shareholders. Lately, Nygren has been emphasizing buyback companies and moving away from utilities and other dividend payers. He says that in recent years, income investors have shifted away from low-yielding bonds and moved to utilities. Because utilities have been slow growers, they typically sold at multiples that were about two thirds of the figure for the S&P 500, he says. But now they trade at a premium to benchmark. "Investors have bid up the prices of dividend stocks, and they have not paid up for many companies that use all their excess cash for share repurchases," he says.
