The logic of an 8.5 percent rally to 622.78 from these levels becomes visually persuasive when you sketch it on the hourly chart.  More immediately, however, a midpoint resistance looms at 573.89, a little more than 16 points above yesterday’s high. That can serve as our minimum upside objective for the near term.  FYI, the minor rally begun from Monday’s 530.01 low projects above it, to 574.29.
