Thomson Reuters reporting SPX forward P/E of 16.99 which is positive, since that is lower than last week while SPX was up slightly. This means earnings estimtes increased. For the near term, this makes 17x 2185 an interesting level to watch in addition to pivots.
This is somewhat countered by a declining Citigroup Economic Surprise Index, but I think as long as that stays above the zero line bulls have benefit of the doubt.
