Berkshire raises stake in Japan’s Mitsubishi to 10.23%

Berkshire Hathaway, through its National Indemnity unit, has increased its stake in Japan's Mitsubishi Corp. to 10.23% from 9.74%, as confirmed by Mitsubishi. This latest move follows Berkshire's earlier stake boosts in five major Japanese trading houses, including Mitsubishi, in March, signaling continued strategic conviction in the sector.

Analysis

Berkshire Hathaway, operating through its National Indemnity Company subsidiary, has increased its ownership in Mitsubishi Corp to 10.23%, a material increase from its previous 9.74% stake. This action is a continuation of a strategy initiated in March, when Berkshire augmented its holdings across five major Japanese trading houses. Crossing the 10% threshold in Mitsubishi signals a deepening conviction and a long-term strategic position, rather than a passive investment. The move is interpreted as a strong bullish signal for the Japanese trading house sector, as it represents a significant capital allocation decision by a globally respected value investor. This continued accumulation suggests that Berkshire perceives sustained value and favorable fundamentals within these diversified conglomerates, which have extensive exposure to global trade and commodities.

Key Decisions for Investors

• Investors should consider this stake increase by Berkshire Hathaway as a strong validation for the Japanese trading house sector, warranting a closer look at Mitsubishi and its peers for potential value opportunities.
• The move to a greater than 10% holding signals significant long-term conviction, suggesting that existing investors in Japanese trading houses may want to maintain or augment their positions based on this signal of institutional confidence.
• Monitor for further stake increases by Berkshire in other Japanese trading houses, as this pattern reinforces a broader strategic thesis on the sector's undervaluation and could precede a wider market re-rating.
