The futures are down seven points at the moment, a tick off their evening lows. So far, it appears to be a routine shakedown to lower the price to more comfortable levels than obtained at Thursday’s close. The selling would become more serious, however, if it were to exceed 991.50 to the downside, creating a bearish impulse leg on the lesser charts.  In a bigger picture, because the decline is following the creation earlier this month of a robustly bullish impulse leg on the weekly chart,  we should assume it is merely corrective. A major new leg up would be signaled by a 37.50-point “booster stage” rally from within the pullback range 923-978.
