Warren Buffett, the most successful dividend investor of all time, owes his success to a simple yet highly effective compounding strategy known as dividend reinvestment programs (DRIP). This strategy leverages the power of compounding by reinvesting dividend earnings into stock, creating a snowballing effect that has made the Oracle of Omaha the success he is today. Long-term dividend investors can take advantage of the DRIP strategy to grow their stock investments into fortunes, and Pfizer Inc (NYSE:PFE) is among the growth stocks with the potential to make you a millionaire in about ten years through dividend compounding.
