It's quite a melt up these last two trading days. I'm marking my sentiment as 'Hold' though I sold my paltry number of shares today. Not sure if AXP is overbought or overvalued, really. IMO, not overvalued, but certainly fully valued. Not a bargain here. Maybe when it consolidates into the mid-70's I'll buy again.
Also, avg volume barely was below average during much of the melt up on Friday, and much lower than average today, so little conviction on this move up. I'd expect it to come back to 80 within the next several days.
