Markets were rattled one week ago when the minutes from the Federal Reserve policy meeting in January left the impression that some bank officials had grown leery of ongoing stimulus programs.
But in subsequent days, Fed officials appeared to walk back from the perception that the minutes had left.

Bernanke is testifying Wednesday before the House Financial Services Committee.
