The market rallied hard making it the 9 out of 11 tradings days with positive gains. SPY has made since 4.2% during that time, but over the past month SPY has made a staggering 8.7%. And as expected, now we are seeing sentiment change.
But, I am not completely sold on the rally yet.
Why? Well, other than the overbought to very overbought readings in most of the ETFs I follow and all of the reasons mentioned in my post yesterday, we are also entering into the weakest period of the month of January. Just look at the DIA chart below for percentage of times positive over the next five trading days.
