A quick upward spike in stocks following Wednesday’s 2 p.m. ET release of the minutes of the Fed’s July 28-29 meeting couldn’t save the market from a second straight daily loss. Within an hour, the indexes had given back all the gain plus a little more, although stocks finished well off their morning lows. The Nasdaq and the S&P 500 lost 0.8% and the Dow Jones industrial average tumbled 0.9% in the stock market today.
