SCHD is an ETF focused on high dividend yield U.S. equities, emphasizing quality and sustainability of dividends. It seeks companies with robust cash flow, solid balance sheets, and track records of consistent payouts. Given the current low interest rate environment, SCHD offers an attractive yield with moderate risk. It's suitable for income-focused investors who want equity exposure with lower volatility than broader market indices. However, it's sensitive to interest rate increases and dividend cuts, which can impact performance.
