Dividend ETFs come in all stripes. A select few focus on blue chip stocks that are screened for financial health. Bonus: They’re among the cheapest exchange traded funds in the equity income category. Ben Johnson, global director of ETF research at Morningstar Inc., especially likes the $2.76 billion Schwab U.S. Dividend Equity (SCHD). He views it as “a very low-cost way to get exposure to a very high-quality portfolio” of dividend payers.
