President Donald Trump’s trade war at least temporarily dashed individual investors’ optimism about the US stock market, setting-off a record setting stampede for the exits just after Tuesday’s opening bell.

In the first hour of trading, the so-called retail investors yanked $1.2 billion out of the US equity market — the largest pullback during that time period since JPMorgan Chase & Co.’s data begin a decade ago, according to Emma Wu, the bank’s global quantitative and derivatives strategist. The pullback from single stocks reached $1.1 billion and was broadly distributed across sectors.
