Mario Gabelli

Mario Joseph Gabelli (born June 19, 1942) is an American stock investor, investment advisor, and financial analyst. He is the founder, chairman, and CEO of Gabelli Asset Management Company Investors (Gamco Investors), an investment firm headquartered in Rye, New York. Forbes Magazine listed him as #1712 in December 2022 on the list of Billionaires, with a net worth of $1.7 billion US dollars.[1] On January 10, 2000, Gabelli was inducted into the "Barron's All Century Team," their list of the most influential mutual fund industry portfolio managers... Gabelli put into practice the theory of value investing he had learned at Columbia. He rated companies not by earnings but cash flow, analyzing a firm in great detail to calculate what he called private-market value: not the share price at which a stock was selling on an exchange, but the price per share someone would be willing to pay in order to buy the whole company. https://en.wikipedia.org/wiki/Mario_Gabelli
