No red socks here, but private equity firm Fenway Partners does boast an eclectic portfolio of midsized companies valued between $100 million and $600 million in the consumer products and logistics sectors, among others. Its holdings include stakes in Easton-Bell Sports (maker of official NFL helmets), scholastic memorabilia maker American Achievement, and temperature-controlled logistics provider Refrigerated Holdings. Upon making its investment in a company, Fenway Partners provides management and strategy advice to boost performance. Despite its name, the company has offices in New York and Los Angeles, but not in Boston, home of baseball's Fenway Park.
