NYSE Resolves Technical Glitch That Showed Berkshire Hathaway Down 99%
On June 3, 2024, the New York Stock Exchange (NYSE) experienced a significant technical glitch that caused Berkshire Hathaway's A-class shares to appear to plummet by nearly 100%. This issue prompted a temporary trading halt and affected several other stocks. The NYSE has since resolved the problem, but the incident raises concerns about the reliability of financial data systems.
The Incident
What Happened?
A technical issue emerged during the morning trading session, causing erroneous price displays. Berkshire Hathaway's A-class shares, typically among the highest-priced on Wall Street, were mistakenly shown as losing almost all their value. This triggered an automatic trading halt to prevent market chaos. Other affected stocks included Barrick Gold and Nuscale Power.
The Cause
The NYSE identified the problem as stemming from the Consolidated Tape Association (CTA), which provides real-time stock quotes for major exchanges. An earlier failure forced the CTA to switch to its disaster recovery center, leading to incorrect price bands being published. These incorrect price bands caused the NYSE’s volatility controls to misfire, displaying inaccurate prices.
Market Reaction
Immediate Impact
The sudden, dramatic drop in Berkshire Hathaway's A-class shares caused alarm among traders and investors. However, the impact on the broader market was minimal. Trading in Berkshire’s B-class shares continued with only a minor decline of less than 1%. The overall market averages remained stable, indicating that the issue was contained.
Response and Resolution
The NYSE acted quickly to address the problem, announcing around 11:45 a.m. ET that the issues were resolved, and trading could resume normally. The rapid response helped to maintain market confidence and prevent widespread panic.
Broader Implications
Reliability of Financial Systems
This incident underscores the vulnerability of even the most advanced financial systems. While such errors are rare, their potential to disrupt markets is significant. The NYSE, along with other exchanges and data providers, must continuously improve their systems to minimize the risk of similar occurrences.
Historical Context
This is not the first time a major exchange has faced technical difficulties. Recent examples include a CME index data feed freeze and a Nasdaq system error that canceled thousands of stock orders. Each incident serves as a reminder of the complexities and risks involved in maintaining real-time financial data systems.
The Significance of Berkshire Hathaway
The A-Class Shares
Berkshire Hathaway's A-class shares are famously expensive and rarely trade in large volumes. Each share was worth about 45% more than the median U.S. home price last week. Warren Buffett, the CEO of Berkshire Hathaway, has deliberately avoided splitting the stock, aiming to attract long-term, investment-oriented shareholders.
The B-Class Shares
To cater to smaller investors, Berkshire issued B-class shares in 1996. These shares are priced at a fraction of the A-class shares, making them more accessible. Despite the technical glitch, the B-class shares were minimally affected, highlighting the stability of Berkshire’s market position.
Lessons Learned
Importance of Robust Systems
The incident highlights the necessity for robust and resilient trading systems. Exchanges and data providers must invest in advanced technologies and disaster recovery plans to handle unexpected failures swiftly. Regular audits and stress tests of these systems are crucial to ensure their reliability.
Transparency and Communication
Swift communication from the NYSE helped to reassure investors and stabilize the market. Transparent and timely updates are essential in managing such crises. This incident demonstrates the importance of clear communication channels between exchanges, regulators, and market participants.
Future Outlook
Enhancements in Technology
The financial industry is likely to see increased investment in technology to prevent similar issues. Innovations in artificial intelligence and machine learning can provide better monitoring and predictive capabilities to detect and mitigate potential problems before they escalate.
Regulatory Oversight
Regulators may also step in to ensure that exchanges have adequate safeguards in place. Enhanced regulatory frameworks could mandate stricter compliance and reporting requirements to bolster market integrity.
Conclusion
The NYSE's swift resolution of the technical glitch that falsely showed Berkshire Hathaway down 99% highlights the critical importance of reliable financial data systems. While the immediate impact was contained, the incident serves as a stark reminder of the vulnerabilities inherent in these systems. Moving forward, continuous improvements in technology and robust regulatory oversight will be essential to maintaining market stability and investor confidence.

Investor Takeaway

The financial industry, including exchanges and data providers, bears the responsibility of ensuring the accuracy and reliability of market data. Ongoing investments in technology and stringent regulatory practices are vital to safeguarding the integrity of financial markets.
