The Putnam Sustainable Leaders Fund primarily allocates capital to equity securities of U.S.-based companies, irrespective of their market capitalization. A core tenet of its strategy is to concentrate on firms that the fund's management identifies as demonstrating robust, financially pertinent sustainable business practices. In addition to these sustainability considerations, the advisor conducts a thorough analysis of prospective investments, scrutinizing factors such as a company's intrinsic valuation, overall financial strength, future growth potential, competitive standing within its sector, projected earnings and cash flows, and its dividend policy, when making buy or sell determinations.
