In an intriguing development that has captured the attention of market enthusiasts and investors alike, Warren Buffett's Berkshire Hathaway recently submitted its latest 13F filing to the U.S. Securities and Exchange Commission (SEC). This occurred on February 14, marking a significant moment for those keen on understanding the maneuverings of one of the investment world's most venerated figures. The 13F filing, which covers the final quarter of the previous year, offers insight into the stock positions held by Berkshire Hathaway, a conglomerate renowned for its strategic investments.

During the last months of the past year, Berkshire Hathaway made notable adjustments to its investment portfolio. One of the most striking shifts was its continued reduction in its long-term position in Bank of America (BoA), a move that had been part of a broader trend observed in recent quarters. Notably, while Buffett had previously trimmed his stake in Apple earlier in the year, he maintained his position in the tech giant during this reporting period, signaling a steadfast belief in its long-term potential.

As of the end of Q4, Berkshire Hathaway reported its U.S. equity portfolio valued at $267 billion, a modest increase from $266 billion in the previous quarter. This slight rise marks the first uptick in a year for Berkshire’s equity holdings, indicating a potentially positive shift in Buffett's investment philosophy. It’s important to note that the 13F filing only reveals a snapshot of long positions, thereby not providing a complete picture of Berkshire's overall investment behavior.

Among the most watched aspects of Buffett’s report are the adjustments made to his top holdings. In the last quarter alone, Buffett initiated a new position in one stock, increased exposure in five others, and reduced stakes in eight. Furthermore, he completely exited three different stocks, highlighting an active management style even for an investor known for his long-term perspectives.

The top ten holdings of Berkshire Hathaway remained unchanged in ranking and consisted of familiar names like Apple, American Express, Bank of America, Coca-Cola, Chevron, Occidental Petroleum, Moody's, Kraft Heinz, Chubb, and Devoted Health. Collectively, these stocks account for a remarkable 89.72% of Berkshire’s total portfolio, underscoring the concentrated nature of Buffett’s investment strategy.

Despite the rankings remaining stable, the ongoing reduction of Bank of America in Berkshire's portfolio is quite telling. The latest 13F revealed that in Q4, Berkshire sold approximately 117.5 million shares of Bank of America, lowering its ownership stake to 8.9%. This decision comes in light of regulatory thresholds, as Berkshire had previously brought its ownership below the 10% threshold that mandates swift disclosure of significant trades. As such, anticipation built among Bank of America shareholders as they awaited the quarterly update for clarity on Buffett's decisions.

As of the most recent close, Buffett's remaining stake in Bank of America is valued at around $31.9 billion. Although there has been speculation regarding the reasons behind Buffett's ongoing reduction since mid-2022, no explicit explanation has been offered thus far. This silence fuels curiosity about Buffett's perspective on the banking sector's future.

Looking deeper into the adjustments made during the last quarter, another area of noticeable change involves the healthcare sector, specifically with Cherwell Health. Berkshire Hathaway reduced its position in this company by approximately 203,000 shares, a decrease of about 0.56% quarter-over-quarter. This action reflects a broader trend of pruning investments that may not align with Buffett’s current strategic outlook.

Interestingly, Occidental Petroleum stands out as the only stock in the top ten holdings that Berkshire increased its stake in during Q4. Towards the end of the year, reports indicated that Berkshire invested over $400 million, acquiring nearly 8.9 million shares at around $46 each. Subsequently, Buffett continued to bolster this position into the new year, albeit further transactions may not yet be reflected in the latest 13F filing.

One fascinating aspect of Berkshire Hathaway's investment strategy is its seemingly unyielding commitment to Apple. In early 2024, despite having previously cut back on Apple shares, the company made no further changes to its position during Q4. Apple remains the cornerstone of Berkshire’s portfolio, commanding an impressive 28% share. The surge in this segment’s value, surpassing $5 billion, not only attests to Apple’s resilience in a competitive market but also reinforces Buffett's long-standing faith in the technology titan's enduring worth.

Other movements during Q4 detailed in the 13F include new acquisitions in the spirits sector with Constellation Brands, as well as investments in Domino’s Pizza, VeriSign, Sirius XM, and Pool Corporation. Of these, Constellation Brands was the sole new position taken by Berkshire, with over 5.6 million shares purchased for more than $1.24 billion.

On the flip side, the quarter saw drastic sell-offs in several positions. Notably, Berkshire slashed its holdings in Citigroup by over 70%, reducing its stake by approximately 40.6 million shares. This aggressive divestiture, combined with the further reduction in Bank of America holdings, indicates Buffett's cautious stance regarding the outlook for bank stocks.

Moreover, the report noted the complete divestment of a beauty stock introduced to the portfolio in Q2, Utah Beauty, showing Buffett's dynamic approach to managing assets based on evolving market conditions.

Looking ahead, investors will be keen to absorb insights from Berkshire Hathaway's forthcoming annual report and Warren Buffett’s legendary letter to shareholders, typically released later in the month. With the investment landscape continually shifting, the information gleaned from these updates is likely to reverberate through market discussions, shaping perceptions of both Berkshire Hathaway's direction and Buffett’s broader investment acumen.
