dividend reinvestment plan financial

"participation in a dividend reinvestment plan"

A dividend reinvestment plan lets shareholders automatically use cash dividends to buy more shares of the same company instead of receiving the money. It matters to investors because it turns regular payouts into a steady way to grow ownership and take advantage of compound returns—like having your savings automatically buy additional slices of a pie over time—while often reducing transaction costs and smoothing purchase timing.
