Here's your week in review for the investment grade corporate bond market:
During the trading week of January 23rd, $71.042 billion of publicly-traded investment grade corporate bonds (LQD) changed hands. On Monday and Tuesday, the ratio of advancers to decliners was relatively even. Notable improvement in the ratio of advancers to decliners began on Wednesday, the day of the Fed's announcement regarding interest rates likely remaining very low, at least through late 2014. The improvement continued through the remainder of the week. The heaviest dollar volume of the week was on Thursday, the same day that advancers outpaced decliners by the largest amount of the week: 2.18 to 1.
