Yeah, yeah, yeah. There's always something that keeps us from pulling the trigger. It's always intelligent, makes sense and seems prudent at the time.

Now if you want to come in, to me it feels too late. Every one of those stocks has made such a move that I can't come in at these levels -- or, if I did, it would be to sell them.

Discipline, trading discipline, is not the enemy. We make the stipulation here that we are too late now. If we made excuses 10% ago about why we didn't buy; we don't rewrite history. We don't say it's now OK to come in.

Now, at

Woulda, shoulda, coulda.
