SPY long overdue for correction

I know people been saying we are overdue for a correction forever. Was going to enter a short at 4200 but did not because I'm 95% a "long" trader. Several traders I follow like Mark Minervi and Gareth Soloway began building net short positions at beginning of summer, I believe around 4000-4300. Minervi posted on July 15th that he was net short the market when S and P was at 4325/50. Usually they are correct but sometimes it takes a little longer to play out.
