2-Day RSI for a 25 : 1 Chance

Another lower close today, and it seems that this year me might abandon the theories about positive seasonalities in December.

With respect to trading with the odds, Thursday’s session might be a make-or-break game (just kidding). By losing another -1.06% today, the SPY‘s (S&P 500 SPDR) 2-day RSI (Relative Strength Index) closed at 10.44 today, while closing at 19.50 on yesterday’s session.

Table I below shows all occurrences (since 1990) and the SPY‘s (S&P 500 SPDR) performance until the end of the week (in this event on Friday, December 16) in the event the 2-day RSI closed below the 12.50 mark from above the day before in December of any year (and at least one remaining session in December of the respective year, means the signal had not been triggered on the final session of the year).

The SPY closed at a higher level on the then following session (in this event on Thursday, December 15) on 25 out of 26 occurrences (thereof the last 25), and chances for a higher close over the remainder of the week were almost 3 : 1 on every single session. In addition, the SPY closed at a higher level at least once 3 sessions later (at the latest) on all 26 occurrences, and never looked back and did not post a single close below the trigger day’s close on 15 out of those 26 occurrences (always compared to the SPY‘s close on the respective trigger day).




I’am looking forward to Thursday’s session …

Have a profitable week,
