If the move to passive investing continues at the same furious pace as in recent years, the total assets under management in U.S. equity passive index funds will outpace AUM in active funds by the end of 2019.

Rather than just chasing performance, fund flows demonstrate investors are increasingly finding comfort in the lower-cost and index-based approach.

At long last, value investing appears primed to play a larger role in the new year. But beware, not all value ETFs are built the same.

Investors may have just adopted factor investing in 2015, but they quickly began implementing between two and four strategies on average.

To these less-than-3-year-old ETFs, age is just a number.

These funds may deflect some of the pain of a correction while keeping an investor in the market.

Thematic ETFs are a good way for investors to round out their asset allocations, but there are some quirks to these funds that require advisors to take a closer look.

Investors in high yield bond ETFs should be focused more on the credit risk than the interest-rate risk.
