Japan\'s stock market is being assessed as close to a \"true revival\" for the first time in 40 years, Business Insider reported. The Nikkei 225 has risen about 30 percent this year and topped 67,000 for the first time, helped by Japan\'s role in the AI semiconductor supply chain. Gains have been supported by semiconductor equipment stocks, SoftBank investments, Berkshire Hathaway purchases, foreign inflows and stronger-than-expected GDP growth.

Berkshire Hathaway has sold its entire stakes in Visa and Mastercard, prompting market focus on whether the move signals a broader portfolio reshuffle. A quarterly report showed Berkshire also fully exited some holdings such as Amazon. The sales are being read as the first major rebalancing under Greg Abel, who is effectively leading portfolio management, and may reflect a move away from positions linked to Todd Combs. Visa’s recent business indicators were described as solid.
