A strong bounce from the low today - both S&P and NQ Futures - with a retest during the last hour and then the final bounce of the day looked quite impressive for a ST rally towards SPM 2690/2700. Long tails in the hourly candles suggest strong buying at that low zone, 2616 to 2619.
But, markets seem vulnerable to plunge at any bad or half-bad news, so it will take some doing to rebound so quickly.
