Dow another All Time High

The Dow hit an all time high today 2/7/2016 20,155.  But If you look underneath the hood of the market and its individual components you can see that only 78% of the stocks were participating.  That is down from when the Dow was at 17,800 back in May and 96% of the stocks were participating.  Another weak point to acknowledge is that no stock within the DOW is making a 52 week high.  How can the index be making all time highs and the stocks are not?  This means we are going up without Institutional Money Flow
