Nov Wednesday 30

What next ?

The SPY closed out November 2011 on a strong note, posting its biggest gain of the trailing quarter, up 4.11% on the close.

My expectation for Thursday, December 1 is mixed, mainly due to the fact that (at least) two setups were triggered today, unfortunately – concerning their forecast for Thursday’s outcome – almost as different as day and night.

There have been thirty occurrences since 1990 of the SPY closing higher 4.0%+. Twenty (or 66.67%) led to an immediate lower close the next day, thereof thirteen occurrences with a 1.0%+ loss versus two occurrences only with a 1.0%+ gain. In addition, 36.67% (one out of every three) of all occurrences fell into the bottom ten percent of the then current worst index returns, a disproportionately high number indicating that major market indices might give back at least some of Wednesday’s extraordinary gains on tomorrow’s session (profit factor of 0.32, and a t-score of -2.18).

On the opposite site: There have been twenty occurrences since 1990 of the SPY posting the biggest gain of the trailing quarter, when at the same time the 2-day RSI (Wilder’s Relative Strength Index) closed above 95 in regularly overbought territory. Contrary to someone’s probable expectation, fifteen (or 75%) led to an immediate higher close the next day, not loosing -0.60%+ on any occurrence, indicating that there might be some upside follow-through on tomorrow’s session (profit factor of 4.91, and a t-score of +1.97). But upside potential on tomorrow’s close will probably be limited: Out of those twenty occurrences, the SPY gained 1.0%+ on the close only once.

Conclusion(s): If in doubt (and no significant edge is provided), stay out (on the sidelines for tomorrow’s session), and a likely scenario on Thursday’s session might be an index trading (significantly) lower at least at some time during Thursday’s session, but closing near unchanged levels (just my 2 cent).

Have a profitable week,
