The S&P 500 was unable to make it four straight weeks of higher prices last week, but the decline it suffered was fractional. So far in the month of July, the index is 2 percent higher. Unless Monday is a sharply down day, July is on track to be the best month for stocks since February, when the reflation trade was still alive. Most of that return has come from the technology sector, although it stumbled a little last week. Also helping has been the energy sector, which came to life in just the past week with a gain of 2 percent, as it tracked the price of oil higher. In fact, with one trading day to go, every sector has made a positive contribution in the month.
