I forgot that Friday the thirteenth is a double edged sword when it comes to good and bad luck....It is always...ALWAYS ...bad luck to sell stocks on Friday the thirteenth..but astronomically good luck for the person that BUYS those same shares..
The one that sells is draining any good luck he may have had into those shares so the one buying them starts to reap the good luck dividend immediately..
It is like buying protection from the evil eye..
Especially on Friday the Thirteenth.
