Peter Thiel sold his entire $74 million portfolio at Thiel Macro in Q4 2024, including positions in Tesla, Microsoft, and Apple, signaling caution about AI and tech stocks.

Ancora Advisors has established a new $148 million position in Americold Realty Trust (COLD), making it the fund's fourth-largest holding. The investment comes as Americold's stock has declined 42% from its 52-week high, trading at a P/CFO of 11x with a 6.87% dividend yield. Despite elevated debt levels, Ancora's long-term investment approach and Americold's stable operations in the temperature-controlled warehousing sector suggest confidence in the REIT's value at current prices.

Warren Buffett retired as CEO of Berkshire Hathaway on December 31, 2025, after more than 50 years. Leading up to his retirement, Buffett was a net seller of stocks for 13 consecutive quarters, accumulating $373.3 billion in cash. This massive cash position signals concern about current market valuations, with the Buffett Indicator hitting an all-time high of 221% and the Shiller P/E ratio at 39-41, well above historical averages. Buffett's actions suggest he believes the stock market is overvalued and is positioning Berkshire Hathaway to capitalize on future market corrections.

In his first annual letter as CEO, Greg Abel signaled that Berkshire Hathaway expects limited activity in its largest equity holdings, including Apple, American Express, Coca-Cola, and Moody's. Abel stated these businesses will "compound over decades," indicating Berkshire will only make significant adjustments if there are fundamental changes to long-term economic prospects. Apple's strong services segment with 75.4% gross margins and 16% sales growth support this long-term holding strategy.

With data center spending projected to grow 32% to $650 billion this year, the article argues Taiwan Semiconductor Manufacturing (TSM) is the best single stock to capitalize on the AI hardware boom. TSM dominates the foundry market with 72% market share, serving major tech companies like Apple and Nvidia.

Ironwood Investment Counsel initiated a new $22.55 million stake in the Akre Focus ETF (AKRE), making it the fund's fourth-largest holding at 3.15% of AUM.

Wedgewood Partners exited its entire $10 million stake in Pool Corporation (POOL) during Q4 2025. Pool's stock has declined 35% over the past year as the company navigates a normalization phase following pandemic-era demand.

Greg Abel has taken over Berkshire Hathaway's $318 billion investment portfolio following Warren Buffett's retirement on December 31, 2025. The portfolio is highly concentrated, with 61% of invested assets in five stocks: Apple, Bank of America, Coca-Cola, American Express, and Chevron. While Abel is unlikely to sell the company's long-term 'indefinite' holdings like Coca-Cola and Amex due to their exceptional yields on cost, Apple and Bank of America may face significant reductions as they no longer represent the bargains they once were.
