Christmas Time …

With two sessions left before Christmas, it may be time to check for the markets performance during the last couple of sessions of a year.

Table I below shows all occurrences (since 1930) and the S&P 500 performance assumed one went long on close of the 3rd last business day before Christmas (like today), and back into cash on close of the last session of the year. ’next session’ and ’2 sessions later’ represent those business days immediately preceding Christmas, and ’3 sessions’ later the session immediately following the Christmas holiday.

Since 1930, the S&P 500 closed at a higher level at the end of the year 64 times, and lower only 17 times. Mean and median change are both exceeding the 1.0%+ threshold. Since 1993, the S&P 500 had always posted at least one higher close over the remainder of year, and never looked back and did not post a single close below the trigger day’s close in 9 out of those 18 years.

Table 1



I (still) expect the S&P 500 to remain firm over the remainder of the year, and turning positive year-to-date may not be ruled out …

Have a profitable week,

    Thanks for your posts!

    I’ve been meaning to ask, when you have “next session” and “2 sessions later” are the returns for each column the return for that day or cumulative since the trigger day?


  2. […] already seen a strong move up from the lows. There are some very interesting stats on Santa rallies here from the excellent (and free) Trading The Odds blog, and you can see that historically we are […]
