In fact, 5 waves can be counted in the move up off of Friday's lows, so it's entirely possible that a top of some significance was established at today's highs, but if so that will need confirmation which isn't yet evident.
Whether the ES/SPX is going to put in a Intermediate or Minor degree top is also an open question. The two pertinent alternate counts are as follows:
Intermediate degree

Minor degree

The Minor degree alternate seems more likely, the move up since the Dec 19 lows looks like a unit to me. Also, in the Intermediate degree alternate Minor Wave 4 did much less damage (34 vs 73 points) and was much quicker (3 days vs 8 days) than Minor W2. The difference is significant - if the ES/SPX is on the verge of a correction of Minor degree it will be much more shallow and short lived than an Intermediate degree sell off.
