Looking once again at the study about the short-term downside risk after a VIX move below its 10-day exponential moving average, historically the low closes for the S&P 500 are usually seen in the third or fourth trade day after the event. The signal was Tuesday, Sept. 10, and the S&P 500 satisfied the average downside risk of a loss of 2.4% and odds favor a positive bias for prices. Based on historical pricing models in the aftermath of a VIX cross below its 10-day exponential, as of the close on Tuesday, Sept. 24, the S&P 500 should have a close near 936.
The upcoming week brings the September Triple Witch, when the monthly stock and index option expirations coincide with the quarterly expiration of futures contracts. This does have the potential to add some volatility, but the historical odds favor a positive bias unless something more dramatic occurs technically.
The current market is a complex situation both technically and psychologically. I think in the short-run the downside risk appears limited versus the potential reward of higher prices sometime in the next 7 trade days.
