Cohen Klingenstein Portfolio holdings
Cohen Klingenstein is an investment adviser that manages portfolios for individuals, trusts, foundations and charities, and it advises one private fund, CK Diversified Fund. The fund began operating in 2013 for investors whose portfolios lack diversification, offering a way to spread their money more widely while limiting taxable gains. Its manager holds that owning a broad mix of securities for the long run can earn market-like returns at market-like risk, and the fund generally avoids sales that create a taxable gain. George Cohen and Thomas Klingenstein are the firm's principal owners.
