While strong cash flow is a key indicator of stability, it doesn’t always translate to superior returns. Some cash-heavy businesses struggle with inefficient spending, slowing demand, or weak competitive positioning.

Not all companies are created equal, and StockStory is here to surface the ones with real upside. Keeping that in mind, here are three cash-producing companies to steer clear of and a few better alternatives.
