It is a proprietary cycle called
the 290CD Blip Crash Cycle. Makes Hindenberg wanna cower.
It goes like this since 2009. Every 290 days we get a quick sharp selloff +/- 2 days. Here are all the dates since 2009, and low and behold every single cycle date we had a big drop. The next one is August 30th.
