There's two things I believe. The high will not be in until March. The high should at least be at SPY 154. We could see a minor pullback here, but it will be a final buy opportunity before the top.
All of this is pure guesswork, at best--just the same as everyone else's opinion. There is no scientific merit to TA, but since it is sort of a poor man's art of statistical analysis, you can always look back and say, oh yeah such and such event was supported by the charts (except of course, when it's not).
