What happens if a stock goes down 100%?

Understanding the Worst-Case Scenario: When a Stock Falls to Zero

Investing in the stock market comes with inherent risks, and one of the most frightening possibilities for any investor is watching a company's share price completely collapse. But what actually happens if a stock goes down 100%?

Put simply, when a stock's price falls all the way to zero, your holdings become entirely worthless. The company essentially ceases to have market value for its common equity holders. While the shares might still technically sit in your brokerage account as a digital reminder, they cannot be sold because there are no buyers willing to purchase something with zero value.

Before a stock hits absolute zero, major exchanges like the New York Stock Exchange or NASDAQ usually step in. Once a share price falls below a certain regulatory threshold—often lingering under a dollar for too long—the stock exchanges will delist those shares. This moves the stock from major public exchanges to over-the-counter (OTC) markets, making it even harder to trade.

Ultimately, experiencing a total loss means the capital you invested in that specific company is gone. This is why diversification and thorough research are fundamental principles of smart investing—they protect your portfolio from a single catastrophic drop.
