The popularity of dividend and low-volatility ETFs shows many investors want a conservative strategy if they’re going to dip a toe in the stock market.

For example, Vanguard Dividend Appreciation ETF (NYSEArca: VIG) is one of the best-selling funds in 2012, raking in $1.9 billion of inflows year to date through July, according to ETF Industry Association data. [An ETF That Tracks Quality Dividend Stocks]

The iShares Dow Jones US Select Dividend (NYSEArca: DVY) has attracted $837 million and SPDR S&P Dividend (NYSEArca: SDY) has brought in $466 million.

“While the belief in the U.S. stock market has taken a hit, ETFs continue to grow. Some of the most successful launches over the past year are in low-volatility products, which buy stocks that exhibit below-average levels of price movement,” said Nicholas Colas, ConvergEx Group chief market strategist, in a note Tuesday.

“Dividend-oriented investing has also been popular,” he wrote. “Old Paradigm: ‘Widows and orphan stocks’ like utilities. New Paradigm: ‘Widows and orphans ETFs’ like emerging market dividend products and a good Min-vol fund.”

It’s not surprising that equity investors are taking a conservative approach after enduring the dot-com and subprime crashes the past decade. Dividend ETFs have also attracted investors looking to boost income in a low-interest-rate market.
