Because bad news is good news. The markets have been high on ZIRP and QE for a decade now, and so when interest rates/inflation increase, the Fed takes action, reducing the price of assets. Good news (more jobs!) means that the Fed will increase rates more (bad news!). Hilariously enough, the actions of the government(s) to bail out various banks are regarded as bad news by the markets which mean good news for asset prices. Yes, it's entirely insane. Welcome to modern capitalism, I suppose.
