Information not available to the public that, if known, would likely cause a company’s stock or bonds to rise or fall—for example, undisclosed earnings, deals, product results, or management plans. It matters because trading on that information gives an unfair advantage, can distort market prices, and is typically illegal or subject to strict rules, so investors watch for proper disclosure and compliance to protect fair, transparent markets.
