Tish'a B'Av and the Stock Market

Tish'a B'Av falls on Saturdays, Sundays, Tuesdays and Thursdays.

Calculating stock market returns for the past 40 years on that day, the same $1 invested every year at the close of the evening prior and pulled out at the end of the day on the 9th of Av, would have turned into $.93656 at the end of 40 years.

The average Tuesday return has been .034% and the average Thursday return has been .025% (including Tish'a B'Av) for the past 45 years. (courtesy of http://techfarm.blogspot.com), while the average Tish'a B'Av return has been -.269% over the past 40.

I dont know what the St Dev has been, nor do I know if Tuesday/ Thursday returns have been different over the past 40 years than the past years. So this is just meant to be fun and a drop interesting and not significant.

Maybe we are lucky that the ninth of Av falls on an open stock market day only 6 out of every 10 years.
