Stocks tried to stabilize on Monday, and Tuesday’s early indications were for Dow and S&P 500 futures to be up almost 1%. Last week’s sell-off may have been the worst opening week for stocks in living memory, but investors have bought every market pullback for over four years now — and the Dow and S&P 500 were both already challenging the formal 10% correction mark.
