FYI: If there's one piece of advice that investors should take to heart, it's that they are almost invariably not smart enough to time the market. Going to cash means not just avoiding the Dow's worst days but missing out on the days of the biggest gains — usually only a few a year — and being left with the difficult task of trying to figure out when to get back into stocks.
But one thing investors have been doing that does make sense is cutting exposure to the S&P 500 — in a big way.
Exchange-traded fund investors bailed on the S&P 500 in March to the tune of near-$20 billion in outflows from two flagship large-cap stock index ETFs, which led outflows among all ETFs.
