DJIA – Multi year market top in now? Go short?

Optimism is at ATH
Nasdaq is lead by 7 or so main stocks
There has not been a major bear since 2007/8 and even then the market pulled back to historic overvaluation if you look at total data in the past 100 years
Mutual fund mngrs cash reserve was at 2% historically low value suggesting a market top
The upper trend line CAGL – capping ascending grind line was tested and reversed, indicating market prices short term unsustainable at those levels.
Prices may go and retest the upper channel line however they could just sell off from now, if we get a retouch then what a beautiful shorting opportunity
Market crashes happen often in September up to late October which we are approaching
Now is time to be aggressively short or to ease off to safety if you are bullish.
Option for much lower prices ?
