FYI: The SPDR S&P 500 ETF (SPY) has seen a huge uptick in trading volume this month as worries around U.S.-China trade negotiations took hold in U.S. markets. The fund has had above-average volume nearly every day in May.
Last week, its trading volume exploded to 70% above average, which is usually around 60 million shares per day. As trade tensions escalated last week, it rose to nearly 145 million shares traded. On Monday it sat at nearly 126 million.
