A, this is where I find sitting tight with shorts to be difficult. While we can all (try to) count the waves and project downside targets, we do not know where she will turn and go back up again.
Remember, there is (still) no better alternative for yield than equities. Bonds are waayyy expensive, cash is useless, and so on.
And there will be bounces aplenty around! How do you distinguish these from a true turn in the market???
A bit philosophical, and maybe rhetorical as well....

Totally agree with you and reason why she will go back up..starting Intermediate V then and to conclude Primary III, then should see a bigger correction in Q4, but the bull should march on into deeper next year for new highs!
3 Things I look at for that possible bottom:
- Signal (candle/positive divergence/bollingerband breach etc)
- Countertrend corrections makes an A, B and C leg down, with C being impulsive just like A so will spot the waves as they happen!
- Is there a cycle date? In this case is one around the 15th Aug
Intermediate waves are large in size so this is just the start....and as today being the 1st and over 1% down August should to look ugly!
