U.S. Sen. Elizabeth Warren (D-Mass.) invested as much as $100,000 in the stock market the day after billionaire Republican Donald Trump won the 2016 presidential election.

Warren, a progressive standard bearer who recently held a town hall on income inequality in America, purchased between $50,000 and $100,000 worth of shares in the Vanguard 500 Index Admiral (VFIAX) fund on November 9, 2016, according to financial disclosures filed with the Senate Clerk.

At the time of Warren’s investment, VFIAX shares were trading around $200 a share; at publication time, those shares were trading for more than $250 a share.

Warren’s capital gain on the investment could have been as much as $25,000.

During the campaign, Warren sharply criticized Trump’s economic plans as unfair to the poor and overly favorable to the wealthy.

The American people aren’t dumb, @realDonaldTrump. We don’t trust you with our nuclear codes AND we don’t trust you with our economy. — Elizabeth Warren (@elizabethforma) August 8, 2016

The man who was ranting & raving on stage tonight has no business controlling our economy OR our nuclear codes. #debatenight — Elizabeth Warren (@elizabethforma) September 27, 2016

According to her financial disclosures, Warren’s net worth could be as high as $10 million.

Calls placed to Warren’s office were not returned. Nor did her office respond to an email asking what part of Trump’s economic plans gave her so much confidence in the stock market.
