Looks like it is buy (risk) on the rumor, sell on the news despite the fact that the Fed aggressively undertook a fresh QE program while extending Operation Twist. Not only has it not put a cap on its buying of Mortgage-backed securities (MBS), it vowed to increase its buying if the labor market does not improve.
Treasuries have dipped a bit as they will not be direct beneficiaries of the Fed’s largesse while stocks are holding onto most of their gains.
The dollar is somewhat better bid after loads of volatility around the time of the release.
