Quote from nonlinear5:
1380 is so obvious as the S/R that it's unlikely to pay (either as support or resistance). To take the most money out of most people, the market would need to cross that level back and forth with large enough margin above and below. Therefore, it's going to happen. Then again, if "most people" are playing 1380 as the resistance, then the market would simply make a straight shot above that level and never come back. Either way, it's not about the 1380 level, but about how the big money decides to move around it.
I am personally long all the way to all time new highs, and quite possibly well beyond that. The spread between the S&P earnings yield and the 10yr bond yield is enormous by all historical standards.
