Key Takeaways

  1. Market Protection Mechanism: Trading halts are a mechanism to protect the market from extreme volatility or potential market manipulation. These suspensions allow for the dissemination of key information, help to prevent panic selling, and also provide time for buyers to assess information and make decisions.
  2. Triggered by Extraordinary Events: Trading halts are triggered by extraordinary market events. This could be due to a pending news announcement, unusual trading activity, or regulatory reasons. The duration of these halts can range from a few minutes to several days but usually lasts for an hour.
  3. No Trading Allowed: During a trading halt, no buying or selling of the stock is allowed. The goal is to prevent drastic price movements and ensure price stability. However, investors may place trades, but they will not be executed until the halt is lifted.


A “Trading Halt” is an important business/finance term that refers to the temporary suspension of trading shares of a particular company on a stock exchange. It is typically initiated by market regulators or the company itself when there are significant news or events that might cause a dramatic effect on the company’s stock price. Trading halts are crucial for maintaining a fair and transparent market. They help prevent panic selling or buying and provide all investors with equal access to significant information. Trading halts ensure that investors have time to understand and absorb the impact of substantial news, thus promoting equitable trading atmosphere.


A Trading Halt is a tool used in finance to safeguard market fairness and investor interests. It is instituted usually by regulatory authorities or exchanges to provide a buffer during periods of unexpected or extreme volatility. Its main purpose is to prevent panic selling or buying, which can greatly disrupt the healthy functioning of the financial markets. Trading halts are preventive measures to curb excessive market speculations and to maintain an orderly trading, thus protecting investors and the overall stability of the market condition.Trading halts come into play during significant company news or announcements, economic developments, or in times when there is speculative trading activity that could impact the integrity of the markets. They allow for a period of pause and therefore help rectify the balance between supply and demand. During this cooling-off period, market participants can absorb the news and accurately evaluate the potential market impact. This, in turn, can reduce the aberrant price movements as well as maintain investor confidence in the market. All in all, trading halts aim to ensure a fair, transparent, and well-functioning market.

Kodak’s Trading Halt in 2020: In July 2020, shares of Eastman Kodak Company were halted by the Security Exchange Commission twice in two days.
