SPX daily indicators
All indicators look bullish and none of them revealed overbought.
Elliott wave reading from 30min chart
Price could be either in the forming of wave C (final state of a counter trend rally - bearish scenario) or in the forming of wave 3 of an impulsive 5 waves up (bullish scenario).
The internal wave structure seems that the movement since 11am of 6/12/12 till now had revealed 4 waves of a 5 waves structure. Wave 4/3-bullish (or 4/C - bearish) had probably finished at 1346.45 - the yesterday's low. If that was correct, then I expect to see a following rebound today to form wave 5/3 (or 5/C).
Wave 5/3 (or 5/C) if it can be made from a rebound today and tomorrow may target 1367.xx or 1381.xx.
