Berkshire Hathaway stock closed on September 18, 2026 with its two share classes showing only modest moves, as Class A shares finished at USD 763,600 on the NYSE, down 0.04 percent, while Class B shares ended at USD 509.77, up 0.11 percent on the same venue. The closing levels sat comfortably between the published intraday highs and lows for both lines, underscoring a contained trading session despite a major governance change.
September 18, 2026 in numbers
Berkshire Hathaway Inc. (ISIN US0846707026) saw its Class A shares trade between an intraday low of USD 760,024 and a high of USD 769,764.25 on September 18, 2026, before closing at USD 763,600, a decline of USD 335.90 or 0.04 percent versus the prior NYSE session, according to data cited by Taiwanese outlet Investor.com.tw.Investor.com.tw The Class B shares traded in a range from USD 506.13 to USD 512.07 on the same day and settled at USD 509.77, a gain of USD 0.57 or 0.11 percent, leaving the more widely held line slightly positive even as the high nominal A shares edged lower.
The muted price response came as Warren Buffett formally stepped back from his long-held role as chairman of Berkshire Hathaway, becoming honorary chairman while his son Howard Buffett assumed the nonexecutive chair position. As Yahoo Finance reported on September 20, 2026, Howard Buffett was appointed chairman of the board with immediate effect, yet market commentary highlighted that investors did not engage in heavy selling of Berkshire shares following the announcement, consistent with the small single-day percentage moves seen in both share classes on September 18, 2026. A broader US equity backdrop featuring mixed index performance on that day, with some benchmarks fractionally higher and others slightly lower per international market wraps, framed Berkshire Hathaway’s numbers as part of a relatively calm session rather than a company-specific selloff.
Board transition shapes today’s focus
Today, September 21, 2026, trading in Berkshire Hathaway centers on the implications of the completed leadership transition at the top of the conglomerate’s board. According to the same report from Yahoo Finance, Warren Buffett continues as chief executive while Howard Buffett serves as nonexecutive chairman, a structure that keeps operational control in familiar hands even as the formal chair role passes to the next generation. Investors today are likely to weigh this governance shift alongside the company’s long-term capital allocation approach and any upcoming disclosures flagged in earnings and corporate calendars, while also monitoring broader US market signals and sector moves that could influence sentiment toward large diversified holding companies such as Berkshire Hathaway.
