The Fed will kick off a two-day meeting to start the week, culminating in an announcement on monetary policy Wednesday. At last month's meeting, the Fed announced plans to extend Operation Twist, the policy of swapping short-term Treasuries in the central bank's portfolio for bonds with a longer duration. While analysts don't expect further quantitative easing or other stimulus out of the Fed this week, investors will be tuned in for any hints of further measures. "It's going to be more of the same rhetoric from the last meeting, that they continue to see that the environment is challenging," said Douglas DePietro, managing director in institutional equities at Evercore Partners. "I don't expect a different body posture out of them, but everybody's looking for the next sign of quantitative easing." Далее»
