Action by the Chinese over the weekend caused a sharp surge in the stock indices in Monday pre-opening trading, though stocks were not able to hold their gains into the close. The cash S&P 500 hit the 50% retracement resistance at 1130, but then closed lower on the day. The key 61.8% resistance stands at 1152 with key support to watch at 1101 and the rising 20-period EMA. The A/D line still looks positive, but needs to surpass the April highs to signal upward acceleration.
