The SPDR Dow Jones Industrial Average ETF (DIA), SPDR S&P 500 ETF Trust (SPY), and Invesco QQQ Trust (QQQ) are all lower just after 11:45 AM EST. The Nasdaq Composite fell 250 points and lost 0.6%, after both it and the S&P 500 notched fresh all-time highs earlier in the session thanks to optimism over corporate earnings and lower inflation data. “One of the concerns is that inflation will start to take hold due to so much monetary and fiscal stimulus, which will cause the Treasury and the Fed to intervene,” said Keith Buchanan, senior portfolio manager at Globalt.
