The Financial Select Sector SPDR ETF, which had outflows of $1.5 billion in the last year, attracted a whopping $4.9 billion in inflows during the week after the election. The sector's flood of new money comes as a direct result of a steepening yield curve in response to Trump's win, an analyst says.
"This is a sign of both the Trump-inspired bullishness for the sector as well as the increase in the size and number of investors using ETFs to express opinions," says Eric Balchunas, an ETF analyst at Bloomberg Intelligence. "This is what it looks like when hot money gets excited. Keep in mind these flows could come out just as easily if the narrative changes again."
