Already priced in
So, there's lots of talk that we no longer need a 'rescue' or 'bailout' simply because the market has rebounded, hence Wall Street is fine. I think there is danger in this assumption that NO plan is needed from Washington. Firstly, I believe the market is pricing in an eventual bailout. As such, people are a little more confident buying in (especially at low prices when company values as a whole really have not changed).
Secondly, other countries are pumping in money and helping with the liquidity crisis to stave off worsening market downturns. Taken together, it's easy to see how the NYSE and other markets have rebounded at least partially since the sell off. Getting complacent and saying "we don't need anything" will only cause a worse selloff without hope of a quick turnaround.
