The futures hung nervously aloft Friday after tripping a conventional ‘sell’ signal down to as low as 2637.50 a day earlier. They could always rally above C=2824.25 just to annoy bears, but that would be bucking an ABCD downtrend whose weight you can judge for yourself (see inset). I’ll suggest using p=2730.88 as a minimum downside projection on Monday/Tuesday, but don’t count on that Hidden Pivot for precise support, since it coincides with an obvious low at 2732.25 recorded on October 12 that the hoi-polloi will be counting on.______ UPDATE (Oct 22, 11:50 p.m.): How completely refreshing! Sellers have knee-capped the futures tonight, bludgeoning them down to within three ticks of the 2730.88 target I’d provided above as a minimum downside projection. If the fun continues, use 2636.50 (slightly adjusted from above) as a minimum price objective.
