I expect a S&P 500 peak this week, then some sideways upward trend next week and a downtrend starting in the middle of October, which reverses before the next FOMC meeting in December 2015.
It would be interesting to see you follow up with a shorter cycle length in addition to the one you already have posted.

Wall Street is greedier than I thought and sold EXACTLY where the real uptrend could have started (based on my technical analysis). This chart is therefore invalid. Please follow my older chart idea which covers the possible upcoming downtrend back to the bottom area this week:
