Quality compounders are flywheels. Said differently, they’re businesses that generate heaps of profits and consistently reinvest them to produce even more profits. Rinse and repeat.

Companies such as these set the gold standard in public market investing. On that note, here are three quality compounders that could amplify your portfolio’s returns.

Why Do We Love SE?
