IBM Employees Lost $400 Million Betting on Company Stock

If you've ever been tempted to load up your 401(k) with shares of the company that signs your paycheck, the story of IBM employees should give you serious pause. Workers at the tech giant collectively absorbed roughly $400 million in losses tied to holding too much company stock — a painful real-world lesson in what financial advisors have been warning about for decades.

The core problem here isn't unique to IBM. When you invest heavily in your employer's stock, you're essentially doubling down on the same entity that already controls your income.
