Portfolio manager Bobby Bierig discusses our value investing philosophy and recently launched Oakmark U.S. Large Cap ETF (OAKM) on First Look ETF.
At Oakmark, we don’t have an opinion about how equities will perform this year, if a recession will start or if the political parties will produce pro-growth candidates during the next election cycle. As long-term investors, we don’t think it matters.
