The WSJ’s Dawn Lim reports that after a temporary lull, the flood of money moving into passively managed index funds and ETFs has resumed. Lim writes:

A decadelong shift of money and power from old-fashioned money managers into index funds resumed its march in 2019.

Last year, net inflows into funds that track markets fell about 30% from the year before, according to Morningstar data. Some firms said fears around slowing global growth and a particularly volatile stock market led investors to take money from asset managementโ€™s most popular products.

Theย 2018 slowdownwas noticeableย atย BlackRockย Inc.,ย Vanguard Group and other large money managers. It led to concerns from some investors about whether a major growth engine for the firms was sputtering.

But now, a stream of cash into funds that track markets is picking up once again.

The recent pickup came ahead of BlackRock andย State Streetย Corp. reporting earnings Friday morning. A rise in flows could help soften the impact of a continuing price war.

Net inflows into index-tracking U.S. mutual funds and exchange-traded funds rose by around 50% in the second quarter of 2019 from a year earlier, according to Morningstar data. For the year ended June 30, passive net inflows increased by about 1% after contracting in the year-ago period. Net inflows measure the difference between money coming in and leaving.

Itโ€™s hard to see how the billions of dollars flowing into funds that pay no attention to value can be healthy for efficient capital allocation, but after a ten-year bull market, nobody wants to hear it.

One might blame easy money, lazy financial advisors, or mutual fund firms who abused their clients with high-fee funds for decades for the trend. But none of that changes the fact that doing whatโ€™s popular on Wall Street has historically been detrimental to oneโ€™s financial health.
