In 1968, a young finance professor at New York University named Edward Altman published a groundbreaking study that would change how investors assess corporate bankruptcy risk forever. His research analyzed 66 companies—half that had filed for bankruptcy and half that remained solvent—to identify the financial ratios that best predicted business failure. The result was the

When Warren Buffett evaluates a potential investment, one of the first numbers he examines is how much debt a company carries relative to its equity. This single metric reveals whether a business operates from a position of financial strength or teeters on the edge of insolvency. The Debt to Equity Ratio cuts through accounting complexity
