Top value strategist Mario Gabelli says that if he were Warren Buffett, he would be looking to purchase companies with some very specific characteristics. Gabelli tells Bloomberg that he’d target companies with “cash flow, sustainability, and a U.S. base that have global earnings power and that can index with inflation”. What might such a company look like? “If you bought Heinz, you could buy a cereal manufacturer,” he speculated. Gabelli also talks about Berkshire’s portfolio construction, and some of its core holdings.
