Tomorrow is Friday the 13th; so what does it mean? Well, if you have triskaidekaphobia then you might not want to leave the house, as that is the fear of the number 13. A fear of the actual day of Friday the 13th is called paraskevidekatriaphobia or friggatriskaidekaphobia. Those are some big words, but again, what does it mean?
First let’s take a breakdown of how each day of the week did from 1928* to 2016. This officially proves that no one likes Monday, as it is by far the worst day of the week for the S&P 500. Speaking of days of the week, did you know that the S&P 500 hasn’t dropped on a Tuesday the past 10 Tuesdays? It was exactly flat this week, but it still wasn’t lower. This is the longest streak without a red Tuesday since early 2013, when we saw 10 in a row. In fact, the S&P 500 hasn’t gone 11 in a row without a red Tuesday since a streak of 13 in a row in early 1972.
Getting to it, the last Friday the 13th was in May 2016, and the S&P 500 lost 0.8%. In fact, the past three Friday the 13ths have all been lower. Per Ryan Detrick, Senior Market Strategist, “First things first, we’d like to stress in no way are we suggesting you invest around any one single day, unless of course you break a mirror and see a black cat going to work tomorrow morning. But sure enough, Friday the 13th historically is weaker than the average Friday, and the results are skewed by some large dips.” It is worth noting that Friday the 13th is up 57.0% of the time, above the average Friday though.
Last, breaking things down by months, tomorrow will be the 14th occurrence of Friday the 13th in January since 1928. This month doesn’t stick out much, as the returns on Friday the 13th in January are fairly flat. The best months for Friday the 13th are June and August, while the worst are November and to no one’s surprise October.
Please remember not to take any of this seriously; we don’t. Everyone have a great Friday the 13th and long holiday weekend if you get Monday off work. Oh, and avoid any mirrors or black cats.
