In this video from Thursday's Boxing Day edition of Investor Beat, host Chris Hill and Motley Fool financials analyst Matt Koppenheffer take a look at Citigroup (NYSE: C) CEO Mike Corbat, and his run since he took over the role from former CEO Vikram Pandit, as well as why Matt considers him 2013's CEO of the year from the financial sector.

Matt discusses how valuation multiples can be useful as a gauge of investor sentiment in a company, and he points to the growth of Citigroup's tangible book value multiple over the past year as a sign that there is increasing investor confidence both in Corbat himself, as well as in the strategy he holds for Citigroup going forward. Matt also names one unlikely voice of support for Citigroup's CEO, and discusses why Pandit wasn't the right man for the job.
