A Dividend Reinvestment Plan (DRIP) is a program that allows investors to reinvest their cash dividends into additional shares of the company's stock instead of receiving the dividends as cash. This can help investors grow their investment over time, as they acquire more shares without incurring brokerage fees. DRIPs are often offered by companies directly, making it easy for shareholders to participate. By automatically reinvesting dividends, investors can take advantage of compound growth, as the new shares can also generate dividends in the future, further increasing their investment potential.
