Trump rally rocked by Comey fears

US stocks had their worst day in eight months on Wednesday as investors wrestled with anxieties over how Washington politics could derail the Trump rally.

Fears spiked over revelations that President Trump allegedly tried to pressure former FBI Director James Comey to drop his probe into Russian-related activities of ex-National Security Adviser Mike Flynn.

Investors worried the crisis could bog down the president’s plans to stimulate the economy.

The Dow Jones industrial average tumbled 373 points, or 1.8 percent, to 20,606.93, its steepest one-day slide since Sept. 9, when the market was spooked by interest rates worries.

The broader-based S&P 500 index also fell 1.8 percent, while the Nasdaq composite index was the worst hit, plunging 2.6 percent.

Trump has hoped to pass his economic agenda this year — including tax cuts, public works spending and regulation rollbacks — but that is beginning to look increasingly difficult as Congress grapples with the possible negative consequences of the Comey controversy.

Investors also were off put by an uncommon silence: the lack of Trump tweets. In the past, the president had used the platform to defend himself against reports he viewed as being biased and unfair.

“I don’t know what that’s about,” Chris Rupkey, chief financial officer at MUFG Union Bank, said about the Twitter outage. “That looks a little interesting, doesn’t it? We’re always just one tweet away.”

Market soothsayers were split on how deep a pullback could go — from 100 points in the blue chip index to a full-on correction of more than 10 percent, or 2,000 points.

Few observers forecast a return to significant market gains in the near term.
