This IS more or less the bottom ... it represents a significant real loss in the market over a considerable amount of time and huge losses short term.
The thing people need to adjust to is that once bottomed the market wont rocket up from here anytime soon ... volatility will continue and the market will trend flat or up 5-10% for a couple of years.
Yes, this is a recession, and no, this is not the bottom. Things that haven't happened yet (but they will):
1. Peak in unemployment.
2. Multiple bank failures, possibly including a big one.
3. Crash in commercial real estate.
4. Further downward revision of GDP figures.
5. Other failures: airlines? GM/Ford?
That's the good case. In the bad case, there is a global sell off of agency and/or treasury bonds, the USD heads for the cellar and loses AAA. The DOW headed down meets gold coming up.
I'm still picking October as an interesting month. It's got a good track history.
But I agree with the other bit -- this is going to be a long one.
