I think you just hit rock bottom. Assuming the treasury will take the bad debt off the overleveraged banks and financial institutions hands, I see no problem with resuming the long term climb upward.
Trillions dumped to save the financial system is not something to be considered a bad thing for markets, be they domestic or international.
I can see 1320 by October's end. 1400 is a bit uncalled for. S&P's targets based on value weighting on the NQ are 2100 for the NDX, which is about 25% higher, but that has a 6-12 month timeframe.
Seriously, the whole reason for the decline has been housing, housing, housing, sub-prime, sub-prime, leverage, leverage. Suddenly, it's all gone. With a bit more regulation and congress admitting they were dumbasses for affirmative action lending rules, I think they figured it out.
