Ajit Jain, Berkshire Hathaway's 73-year-old vice chairman of insurance operations, sold 200 Class A shares for approximately $139 million, significantly reducing his stake in the conglomerate. This sale, representing 55% of his total holdings, occurred at an average price of $695,418 per share. Jain now directly owns 61 shares, with additional shares held through family trusts and his non-profit, the Jain Foundation. Analysts suggest that Jain's decision may indicate his belief that Berkshire's stock is fully valued, especially given its recent surge to a $1 trillion market capitalization. Tax considerations might also have influenced the timing of the sale. Jain has been instrumental in Berkshire's success, particularly in the reinsurance sector and GEICO's turnaround.
