The markets are having their second down day in a row. This is coming off a surge last week to new all time highs on all major indexes. So why are these two small down days any different than small down days in the past? There is only one difference, however it is a strange and important one. The fall over the last two days has happened on the lightest trading days of the year. All it takes is a few small retail buyers to push the market up on extremely light trading days. However, we are not seeing that. There has been little to no institutional buying for a long time, but the retail investor continued to push the markets up. Now that is not happening. Could this be a bigger signal that most would believe? Without large institutions buying and now small investors not buying, could the upside be coming to an end?
