The man in charge of the empire of mutual funds, otherwise known as Vanguard, went to bed early on election night, and woke up stunned by news of Donald Trump’s presidential victory.

It turns out Vanguard CEO Bill McNabb needed that extra sleep on the day after the historic upset. The Malvern-based investment-management firm fielded 20 percent more calls than normal — totaling 40,000 — on Nov. 9, according to a report in The Wall Street Journal by Sarah Krouse.

“We didn’t see this coming,” McNabb said.

Luckily for Vanguard, the markets settled themselves during the day. However, McNabb noted that, in the wake of the newfound economic uncertainty brought about by a regime change at the White House, “it wouldn’t surprise us if the Fed delays” an interest rate increase, despite his opinion that “we think the fundamentals suggest there will be” one.
