The equities market largely moved higher after a sell-off over the past week. U.S. stocks bounced Tuesday as investors brushed off Federal Reserve Chairwoman Janet Yellen’s remarks before Congress and focused on the upcoming United Kingdom referendum vote on European Union membership.

In Congress, Yellen said that while the Fed expects gradual rate increases later, “considerable uncertainty about the economic outlook” has been a more pressing issue, the Wall Street Journal reports.

Yellen’s prepared remarks were largely in line with expectations, especially given the backdrop of a pending so-called Brexit vote, and the equities held up in late Tuesday trading.

Meanwhile, the equities market has exhibited high correlation to sentiment over the U.K.’s June 23 referendum, falling and rising on survey polls ahead of the vote. For instance, over the past week, stocks plunged when polls revealed more Britons were leaning toward an exit vote and the recent rebound came off recent polls showing a “remain” majority.

While economists expect the short-term impact of a “Brexit” to be negative for U.K. growth, investors’ focus on the referendum “shows the fragility of global markets and the general low appetite for risk, with so many question marks out there in the global economy,” Carl Hammer, chief currency strategist at SEB, told the WSJ.
