The best way to protect yourself as the Fed wades into Europe

Is there no problem that can't be solved with the application of some easy money? Markets around the world rocketed yesterday as the world's central banks got fed up waiting for Europe to do something. The Federal Reserve and the rest of them ganged up for an assault on the forces of bearishness, spraying more cheap money into the system in a concerted effort. It worked. The Dow Jones index is back in positive territory for the year. The German Dax gained 5%. And the FTSE 100 was up 3%. So what exactly happened yesterday? And is this a turning point in the eurozone crisis, or just another false dawn?
