time to short?

This stock has had a run since April from 5.60 and looks overbought. Mostly ran up on the index changes, inclusion in asx 100.

Now its had 3 lower lows in the last 3 trading sessions and 650 looks like a double top (previous high in Jan before it dumped). I reckon its a short here with stop 655.

Other pts...

JP Mogan has been selling.

Co. has huge debt, still making a loss (10c ps).

Nasdaq and techs looking weaker.

Any comments welcomed from shorters like syringe..
