Berkshire Hathaway stock (ISIN US0846707026) closed at USD 507.00 on the New York Stock Exchange as of September 10, 2026, marking a 0.06% gain versus the previous close and leaving the shares in the middle of their 52-week trading range per recent portal data.

Alphabet stake reshapes Berkshire portfolio

Portfolio moves are a key catalyst for Berkshire Hathaway stock right now, with the conglomerate sharply increasing its exposure to Alphabet in recent quarters. As Yahoo Finance reported on September 11, 2026, Berkshire currently holds about 79 million Alphabet shares valued at roughly USD 28.2 billion, making the Google parent one of its largest equity positions.

The increased tech exposure builds on a broader capital allocation shift that has unfolded over recent quarters. According to The Motley Fool on September 11, 2026, about 82% of Berkshire’s approximately USD 360 billion equity portfolio was concentrated in just 10 stocks as of the close on September 4, 2026, underscoring how a handful of large positions, including Apple, American Express and Alphabet, now dominate the investment mix.

Recent buying and cash position support the shares

For investors in Berkshire Hathaway stock, the latest disclosed transaction data give a clearer picture of how management is balancing opportunity and risk. As The Motley Fool noted on September 10, 2026, Berkshire bought about USD 23.5 billion of stocks in the second quarter of 2026 while selling roughly USD 3.7 billion, ending a 14-quarter stretch of net stock selling. Over the same period, the company held around USD 365 billion in cash, cash equivalents and Treasury bills at quarter end, highlighting that the balance sheet can support both opportunistic buying and risk management.

That combination of renewed net stock purchases and a very large cash pile is an important backdrop for Berkshire Hathaway stock. It means the conglomerate is no longer strictly in de-risking mode yet remains positioned to take advantage of market dislocations. For retail investors, the visible tilt toward large, cash-generative names such as Apple, American Express and Alphabet suggests that the equity portfolio is designed to compound over time while being buttressed by substantial liquidity.

Stock price and technical picture

In the equity market, Berkshire Hathaway’s Class B shares have been trading steadily in recent sessions. Portal data show a closing price of USD 506.72 on September 9, 2026, followed by an intraday move to USD 507.00 by the close on September 10, 2026, equivalent to a daily rise of about USD 0.28 or 0.06%. The stock is described as trading in the middle of its 52-week range and above its 200-day simple moving average, indicating that, from a technical perspective, the trend remains constructive but not stretched toward either the high or low end of the past year.

Additional technical readings point to a modestly softer tone on some shorter-term indicators. A recent overview shows Berkshire Hathaway Class B shares quoted around USD 504.96 on September 10, 2026, a decline of USD 1.76 or 0.35% on that snapshot, with the 200-day moving average around USD 508.26. Taken together, these values suggest the shares have been oscillating in a relatively narrow band just below their longer-term average price, rather than breaking out decisively in either direction.

Class A shares underscore the conglomerate’s scale

The performance of Berkshire Hathaway’s Class A shares adds another dimension for investors assessing Berkshire Hathaway stock. According to data compiled by a US stock portal as of September 10, 2026, Class A shares closed at approximately USD 760,029.35, up about 0.48% versus the prior day’s close of USD 759,141.00. Over the same session, the shares reached an intraday high near USD 764,069.00 and a low around USD 752,155.00, on a trading volume of 151 shares.

These five and six-figure prices for the Class A shares underscore the sheer scale of Berkshire Hathaway’s market value and reflect the company’s longstanding decision not to split that class of stock. While most retail investors access Berkshire Hathaway stock via the more affordable Class B shares, the Class A line remains a barometer of the conglomerate’s perceived value among long-term holders and institutions.

Closing view on Berkshire Hathaway stock

With Berkshire Hathaway stock closing at USD 507.00 on the New York Stock Exchange as of September 10, 2026, and trading around the middle of its 52-week range, the shares currently reflect a balance between the company’s concentrated bets on a handful of large holdings and its substantial cash position. For investors, the key questions over the coming quarters will be how management deploys that cash and whether portfolio moves, such as the expanded Alphabet stake, continue to support steady compounding in book value and market price.
