Great article on investing after QE2 (or trading for that matter), posted to http://www.ritholtz.com by the Global Macro Monitor.
Unless credit markets begin to recover in a significant way, the source of new liquidity to drive major markets is in question, in our opinion.

As always, be prepared for changes in market direction by having a plan for your long term investing success.
