What Happens If a Stock Goes to Zero? Losses, Bankruptcy and Delisting

Yes, a stock can go to zero, or so close to it that the difference does not matter. It happens when a company fails and its shares end up with no claim on anything: in a bankruptcy, shareholders are paid last, and the SEC's investor bulletin warns that "any common stock in a bankrupt company is likely to be worthless" (SEC, investor.gov, Bankruptcy for a Public Company, March 31, 2015). What you lose depends on how you hold the stock, and that is where the question "can you lose more than you invested?" needs sorting out.

What you can lose, by position

A price cannot go below zero, so a cash buyer's loss stops at the amount paid. Borrowing changes that: the SEC's margin bulletin puts it plainly, "You can lose more money than you have invested" (SEC, investor.gov, Understanding Margin Accounts, June 10, 2021). If you bought $10,000 of stock with $5,000 of your own and $5,000 borrowed, and the stock went to zero, your $5,000 is gone and the $5,000 loan is still due. See cash account vs margin account. The short seller is on the other side: a fall to zero is the best case, and the risk runs the other way, since a price has no ceiling.

How a stock gets to zero

The usual path is bankruptcy. FINRA lists the order in which a failed company's money is paid out: secured bondholders first, then unsecured bondholders, holders of subordinated debt, preferred stockholders, and common stockholders last (FINRA, What a Corporate Bankruptcy Means for Shareholders, November 16, 2021).

• Chapter 7: liquidation. The company stops operating, a trustee sells its assets, and the proceeds go down the line above. FINRA notes that "more often than not, shareholders of bankrupt companies see little to no compensation for their investments."
• Chapter 11: reorganization. The company keeps operating under a court-approved plan. The SEC bulletin of March 31, 2015 notes that when companies emerge, the old stock "is usually worthless" because "in most instances, the company's plan of reorganization will cancel the existing shares." FINRA adds that cases where old shares are exchanged for shares of the reorganized company "are especially uncommon."

Can a bankrupt stock still trade?

Yes, which is why prices of bankrupt companies can stay above zero for a long time. "There is no federal law that prohibits trading of securities of a company solely because it is in bankruptcy," the SEC bulletin says. Bankrupt companies are generally unable to meet NYSE or Nasdaq listing standards and get delisted, but their shares may keep trading over the counter. A "Q" may be added to the symbol to flag the bankruptcy; if the company issues new stock under its plan, the new shares trade without it. A price above zero on an old, "Q"-marked share is not a sign that it will be worth anything after the plan.

Two bankruptcies, with dates

• Lehman Brothers, September 15, 2008 to March 6, 2012. The investment bank filed for bankruptcy early on Monday, September 15, after a weekend of meetings at the Federal Reserve Bank of New York failed to find a buyer or a private solution (Federal Reserve History; Bernanke testimony, April 20, 2010). When its plan took effect on March 6, 2012, all existing common and preferred shares of Lehman Brothers Holdings were canceled; former holders got only non-transferable interests in a trust, and the company said it did not expect those interests to receive any distributions, since every creditor had to be paid in full first (Lehman Brothers Holdings, Form 8-K, March 6, 2012).
• Hertz, May 22, 2020 to June 30, 2021. Hertz Global Holdings filed voluntary Chapter 11 petitions in Delaware on May 22, 2020 (Hertz press release, May 22, 2020); its plan was confirmed on June 10, 2021, and it emerged from bankruptcy on June 30, 2021 (Hertz, second quarter 2021 results). On the day the plan was confirmed, Hertz said its plan provided for paying all creditors in full in cash and for existing shareholders to receive "more than $1 billion of value" (Hertz press release, June 10, 2021, read November 2, 2026).

Why a stock rarely shows 0.00 on an exchange

A listed stock is usually delisted long before its price reaches zero. On the New York Stock Exchange, for example, a company falls below the continued listing standards when its average closing price is less than $1.00 over 30 consecutive trading days. It then has six months to bring both its closing price and its 30-day average back to at least $1.00, or the exchange starts suspension and delisting procedures; if the stock trades below $0.10, the exchange starts them promptly, whatever the cure period (SEC, Release No. 34-104385, December 12, 2025, describing Section 802.01C of the NYSE Listed Company Manual). On August 14, 2026, the SEC approved an NYSE rule change that, from July 1, 2027, suspends trading immediately and starts delisting proceedings when a stock closes below $0.25 on any trading day, with no cure period; the exchange chose that date to give companies time for reverse stock splits (SEC, Release No. 34-106133, August 14, 2026). After that, any trading moves over the counter, where prices of a fraction of a cent are possible. A quote of 0.00 is often a rounding of such a price, not a true zero.

Prices near zero for a moment

A price can also touch zero by accident. On May 6, 2010, between 2:40 and 3:00 p.m., over 20,000 trades in more than 300 securities were executed at prices 60% or more away from their 2:40 p.m. prices, many of them "at prices of a penny or less," after market makers and other liquidity providers widened their quotes, cut what they offered, or withdrew from the market. The exchanges and FINRA canceled those trades after the close (CFTC and SEC staff report, September 30, 2010). A healthy company's stock can print near zero for seconds without being worth zero.

Can the whole market go to zero?

For an index to reach zero, every company in it would have to fail at once. On our own data the deepest falls were large but not total. On monthly closes of an S&P 500 ETF, dividend-adjusted, from February 1993 to September 2026, the deepest fall was 50.8%, from October 2007 to February 2009, and the price was back above its 2007 peak by March 2012. On weekly closes of Bitcoin, a single asset with no company behind it, from August 2017 to October 2026, the deepest fall was 82.9%, from December 2017 to December 2018, recovered by November 2020.

A narrower fund can fall much further. From February 2017 to September 2026, the same S&P 500 ETF fell at most 23.9% on monthly closes, from December 2021 to September 2022, and had recovered by December 2023. Over the same months, the ARK Innovation ETF, a far narrower fund, fell 77.1% from January 2021 to December 2022 and was still below that peak in September 2026. It still ended the period ahead, at $4.18 per dollar invested against $3.75, so a deeper fall is not a lower return. Neither fund went to zero; a single company, with no spread at all, can.

Falling stocks can bounce on the way down. A short rally inside a steep fall is called a dead cat bounce; see dead cat bounce.

Taxes: a worthless stock is a capital loss

For U.S. taxpayers, the IRS treats stock that became completely worthless during the tax year as though it was sold on the last day of that year, which decides whether the loss is short term or long term; it is reported on Form 8949. A loss not claimed on the original return can be claimed on an amended return, Form 1040-X, within 7 years from the date the original return was due, or 2 years from the date the tax was paid, whichever is later (IRS Publication 550 (2025), Worthless Securities). Capital losses offset capital gains; beyond that, up to $3,000 a year ($1,500 if married filing separately) can be deducted from other income, and the rest carries forward to later years (IRS Topic 409, page updated September 24, 2026). This is a summary of the IRS pages as read on November 2, 2026, not tax advice.

How to protect yourself

• Size every position for zero. Ask what happens to the account if this one holding goes to zero, and keep that loss bearable; see position size.
• Avoid margin on speculative stocks. It is what turns a total loss of the position into a debt.
• Watch the balance sheet. A company that cannot cover its interest is closer to the line; see interest coverage ratio.
• Be careful with very cheap stocks. A low price is not a margin of safety; see penny stocks.
