It's been a long dry spell for triskadecaphiles. We haven't had a Friday the 13th since July of 2012.
That 13 calendar months without a Friday the 13th is the longest such stretch you'll ever see. The last such dry spell was 11 years ago, ending September 13, 2002. On that day, President Bush met with reporters, beginning to build the case for the Iraq war. Today, President Obama is taking the day off. On September 13, 2002, the S&P 500 traded up 0.3% to close at 890, near five-year lows. Today the S&P has almost doubled from there for an annual total return of more than 8% and is near last month's all-time high.
The next such streak without a Friday the 13th will end September 13, 2019. All 13-month stretches without a Friday the 13th end with a Friday the 13th in September or October.
