Berkshire became a net stock buyer after 14 quarters, but that is not a broad market call

Berkshire Hathaway bought $19.8 billion more equities than it sold in the second quarter of 2026. That ended 14 consecutive quarters of net stock selling. The Kobeissi Letter reads the move as Berkshire leaning bullish again.

Part of that reading is fair. Cash fell, while purchases of outside stocks and Berkshire's own shares both increased. Yet spending cash does not by itself mean that the whole U.S. equity market looks cheap. Berkshire selected a few stocks, its own shares and a homebuilder acquired for $6.8 billion. It did not buy the market.

A turn after 14 quarters

Reuters also counted the quarter as Berkshire’s first net-buying period after 14 quarters of net sales. Berkshire added $10 billion to Alphabet and repurchased $4.527 billion of its own shares during the quarter. Alphabet had become one of Berkshire's five largest equity holdings by June 30.

Outside-stock purchases and buybacks need to be separated. An outside security is chosen for its expected return and business outlook. Berkshire's own shares are governed by a published rule. The chief executive may buy only when the price is below a conservatively estimated intrinsic value after consulting the chairman. There is no promised minimum or maximum, and purchases may not push cash and Treasury bills below $30 billion. That rule narrows the buyback signal to Berkshire's own valuation rather than the U.S. market as a whole. At the same time, the sharp acceleration from Q1 shows that capital allocation has changed in practice under the new chief executive.

One pool, three signals

Three ways of reducing cash carry different messages. Buying Alphabet expresses a view on one company's future cash flows. Repurchasing Berkshire says its own shares are below intrinsic value. Buying an entire homebuilder transfers control of an operating business. Cash left the same pool, but the valuation questions are different. Calling all three a broad bullish market call erases what Berkshire actually judged to be cheap.

Berkshire's next 10-Q

One quarter is not enough to declare a permanent regime change. Berkshire still held $359.2 billion in cash and Treasury bills, more than eleven times the $30 billion floor written into its buyback policy. Reuters also reported that more than $3.3 billion of buybacks continued in July. If net purchases of outside stocks, buybacks and acquisitions continue together next quarter, the case for a sustained shift toward deploying cash will strengthen. If outside-stock purchases return to net sales while buybacks remain, this quarter will look like a judgment about Berkshire and a handful of transactions, not the market. That is why the useful question is not simply whether Berkshire turned bullish, but what it bought and under which rule.
