Long Streaks of Not Losing

Today marked the 17th consecutive session where the SPY‘s (S&P 500 SPDR) hasn’t lost more than -0.52% on a close to close basis (besides the fact that this is the 2nd lower close only during the last 11 sessions).

Historically, comparable streaks were regularly indicative of higher prices ahead.

Table I below shows the SPY‘s (S&P 500 SPDR) performance (cumulative returns) one, two, and three sessions, 1 week, 1 month later, and by the time the SPY posted its first lower close in excess of -0.55% in the event the SPY hadn’t lost -0.52% on a close to close basis for 17 or more trading days (for the first time in a two weeks time frame, means only the first occurrence during a 10 day time frame has been accounted for).

The SPY closed at an even higher level two days, three days, 1 week and 1 month later (on 17 out of the last 18 occurrences), and at the end of the month as well on 3 (or more) out of every 4 occurrences, and 1.0%+ moves on the upside outnumbered -1.0%+ moves on the downside by a very wide margin.

In addition, the SPY had never lost 1.0% on the then following session (in this event on Wednesday, January 25), and by the time the SPY lost -0.55% ending the then current streak, the index had closed more often on a (significantly) higher level (22x above the trigger day, 15x below the trigger day, and 11 : 3 closes up 1.0%+ vs. down -1.0%+).

SPY did not loose -0.52% on the close on 17+ consecutive sessions



For the time being, shorting the market most probably remains a receipt for disaster (and Wednesday will be an FOMC announcement session, another positive seasonality).

Have a profitable week,
