A midpoint support at 735.90 was my minimum downside expectation as trading continued into Wednesday evening, but any lower would imply 722.10. The latter number would not be particularly useful for bottom-fishing, however, since it coincides with some visually supportive lows made earlier in the week. If they, and the pivot, fail, we could expect a test of the 681.00 low recorded on October 24. Alternatively, we should reserve our bullish excitement for a thrust that creates a solid impulse leg on the hourly chart. For today, that would mean a print at 782.30.
