No session would be complete, it seems, without the obligatory Whoopee Cushion rally in the final hour. Friday gave us yet another, although it wasn’t quite strong enough to push the broad average to a positive close. Nor has there been any follow-through so far Sunday evening. The mini-indexes were trading mostly in an ultratight, two-tick range after opening a couple of points lower.  It seems unlikely they will pick up the pace this evening, since they will be anticipating the closure of U.S. markets on Monday for President’s Day. In any case, there is little to recommend for night owls at the moment.
