David Tepper’s Appaloosa shows a quiet bet against Apple, and even against Berkshire Hathaway

Billionaire hedge fund manager David Tepper is known for leaning aggressively into contrarian ideas, and his latest move is drawing fresh attention for the targets he chose. Yahoo Finance reported that Appaloosa Management disclosed in a recent 13F filing (a quarterly regulatory report that shows certain stock holdings and positions) that it is short Apple, one of the most widely owned large-cap companies in the United States.

The report also pointed to a second, even more provocative target, Berkshire Hathaway. Yahoo Finance said Appaloosa took positions that were effectively a bet against Berkshire Hathaway, the conglomerate long associated with Warren Buffett’s buy-and-hold reputation, which Yahoo Finance described as a stock Buffett would not sell.

In Appaloosa’s case, the practical meaning of a “short” is that the fund profits if the stock price falls, typically by borrowing shares and selling them, or by using derivatives tied to the stock. A short position is generally viewed as a view that downside risks outweigh upside, even for companies that remain popular with long-term investors.

The Yahoo Finance report framed the Apple and Berkshire moves as part of a broader pattern of Tepper’s willingness to challenge consensus valuations rather than mirror them. Still, the regulatory 13F form is not a complete view of an investor’s full book, because it does not capture every derivative or non-U.S. holding, and it does not necessarily show the full size or timing of trades with precision.

For Apple, a short at the margin is notable because the company is not just a consumer brand but also a large, widely benchmarked enterprise with significant recurring revenue streams from services. The market implication is that at least one prominent money manager sees enough skepticism in near- to medium-term expectations to position against the stock.

For Berkshire Hathaway, the implication is different but just as pointed. Berkshire sits at the center of Buffett’s operating philosophy and investor mythology. Yahoo Finance’s description of Appaloosa taking an even-cautious stance against that name underscores that Tepper’s bet is not confined to one industry or one type of business, but to the broader market assumptions embedded in “quality” stocks.

What is not clear from the public reporting highlighted by Yahoo Finance is the magnitude of the positions, such as the specific number of shares or the exact economics of the hedge structure, because the filing details and any explanatory commentary are not included in the portion summarized for readers. Without access to the full filing tables in this account, it is also not possible to verify any changes versus prior quarters from the information available here.

Going forward, investors will likely watch whether Appaloosa’s exposure persists in subsequent 13F reports and whether Apple and Berkshire see broader signs of investor rotation. In parallel, the market will look for any additional disclosures or commentary from hedge fund managers that could clarify whether the short thesis centers on valuation, competitive dynamics, or company-specific execution risks.
