Goldman named David Solomon, a co-head of its investment banking division to the position, along with Harvey Schwartz, the current chief financial officer. The two men will replace Gary Cohn, who is joining the Trump administration. Cramer says there are more talented people at Goldman Sachs than any other company he studies. Cramer is a former employee of Goldman.
