Why should anyone buy Goldman Sachs? In this video, Matt Koppenheffer gives three reasons you should. First, Goldman is viewed as being the premier investment bank. Last year, and this year to date, Goldman is No. 1 in mergers and acquisitions and equity offerings by value. Second, Goldman currently trades a smidge above tangible book value. Historically, Goldman has traded at or above twice tangible book value, making its current valuation quite attractive. Lastly, Goldman attracts top flight talent that, in turn, helps it do an increasingly better job of making money.
