How can I detect potential fraud in a company before investing in them?
Even without fraud, a company can get into serious trouble overnight, often through no fault of their own. That's part of the hazard of being part owner of a company -- which is what a share of stock is. As a minority owner not involved in actually running the business, there really isn't a lot you can do about that excep to play the odds and think about how that risk compares to the profit you're taking (which is one reason the current emphasis on stock price rather than dividends is considered a departure from traditional investing) and, as everyone else has said, avoid putting too much of your wealth in one place.
