Low flow
Thanks in part to huge volume in General Electric, the S&P 500 closed up more than 0.5%, yet more than 70% of NYSE volume flowed into declining securities. The only dates since 1962 when the S&P was up that much with an Up Volume Ratio below 30% were 2007-11-27 and 2008-10-23 when banks were getting hammered. There were 31 days when the S&P was up at least 0.5% and Up Volume was less than 50%, and there was some weakness going forward, with gains over the next month only 43% of the time.
