Warren Buffett Is Sounding Off on Market Risk and Investors Should Listen

Warren Buffett has given a couple of interviews to CNBC in recent months that have provided some fascinating color on the state of the markets. Tangentially, they touched on the biggest debate in the market right now: the sustainability of the artificial intelligence (AI) spending boom and its implications for stocks like Alphabet (NASDAQ: GOOGL) (NASDAQ: GOOG) and Oracle (NYSE: ORCL).

My take on it is that there's definitely reason for near-term caution, but investors should look to take advantage of any significant market-led weakness. Here's why.

Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »

In the first interview in May, Buffett noted that "we've never had people in a more gambling mood than now. But that doesn't mean that investing is terrible. It does mean that prices for an awful lot of things will look very silly."

A month later, Buffett was asked about Berkshire Hathaway 's (NYSE: BRKA) (NYSE: BRKB) aggressive purchasing of Alphabet stock in 2026, a position that now represents about 12.6% of its public equity holdings. Buffett confirmed he had initiated it, with the decision made by Greg Abel.

Naturally, the interviewer then tried to discern why Buffett was comfortable buying Alphabet over other hyperscalers that are currently spending heavily on AI-related capital expenditures. Buffett's response was: "Yes, well, I don't want to sit around knocking the others. They don't have any choice, yes," and then confirmed he meant capital spending, before going on to say: "They're now playing a game in many cases where they, or some cases where they're playing a game they don't want to play."

Reading between the lines, it appears that Buffett is cautious on equity market valuations right now. He's also mindful that some hyperscalers have no choice but to invest heavily in AI, even if they might not want to. However, he's happy for Berkshire to build a near $38 billion position in one hyperscaler: Google's owner, Alphabet.

Based on the rising cost of insuring Oracle's debt against default, as measured by credit default swap pricing, bond markets are pricing in the possibility of a default. To put the current mid-market CDS spread of 192 basis points (where 100 basis points equals 1%) into context, the market usually assumes a 40% recovery rate on defaulted debt.
