SPX managed to hold just above the MR1 2003. Resuming above that on Wednesday would be the easy bullish path. If below then still have key support in the YP / Q4P zone 1963-73 respectively. For SPX at least I give the bull scenario the benefit of the doubt above that support zone.

That said, some cracks have appeared in the rally. A pullback after a huge run is normal; it is the depth of the drop and then then the strength of the next move up that will give clues to whether bull market is returning in the style of 2011 recovery, or if the new quarter buying / re-balancing move is over and the downtrend is about to resume.
