Berkshire Hathaway (BRK.B) Stock: New Insider Purchase Signals Confidence Despite Market Underperformance
Berkshire Hathaway Inc., BRK-B Michael OSullivan acquired 536 shares of BRK.B at approximately $468 per share. His total holdings now stand at 663 shares valued at roughly $300,000, based on a Form 4 disclosure filed with the Securities and Exchange Commission. O‘Sullivan assumed his role at Berkshire on January 1, joining from Snap Inc. to fill a newly established in-house general counsel position. His background includes more than two decades with Munger, Tolles & Olson — the prestigious law firm that was co-founded by Berkshire’s late Vice Chairman Charlie Munger. This transaction represents just the second instance of insider buying in 2026. Earlier, CEO Greg Abel purchased 21 shares of Class A stock for approximately $15 million on March 4, financed through after-tax proceeds from his $25 million 2026 compensation package. Abel has committed to making similar annual investments. BRK.B concluded Wednesday‘s trading session just under $470. Year-to-date, the stock has declined approximately 6.5%, contrasting sharply with the S&P 500’s roughly 7.6% gain during the identical timeframe — creating a performance gap of about 14 percentage points. Looking at the trailing twelve-month period, the underperformance becomes even more pronounced, with BRK.B lagging the benchmark index by approximately 40 percentage points.
