Stock Market S&P 500 Down 10% into Early September?

The chart below shows the weekly SPX since late 2008 to the current. According to my calculations, Wave Y of a WXY “Y” of B WAVE terminated at 2168/69 on July 14.  Everything after that has been irregular and part of wave X of “Z” into November 21. Wave X is being subdivided xyz and y of that wave terminated today at 2193/94.

My down side target is near 1970 by Sept 9, with the big wave down “c”of Z from the solar/new moon eclipse top of Sept 1 to the expected ten week low of September 9. After that, a new high around October 17 near 2241 and then down into the November 21 expected low near 1638.
