If a bear market is coming, an AI downturn will be a major factor.
Oracle and CoreWeave are both relying on expensive debt to fuel growth, making them vulnerable.
Berkshire Hathaway is built to not just survive market downturns, but use them to its advantage.
It's been quite a ride for investors this year. After an early sell-off, the S&P 500 is up about 21% from its low in March, while the tech-heavy Nasdaq Composite is once again setting records, topping 27,200 just last week.
But a lot is happening all at once. With global instability, elevated oil prices, and bond yields at nearly two-decade highs, some investors are nervous that the recent run will reverse.

If that happens, and a bear market -- a 20% drop in the stock market -- comes, I think a major slowdown in AI spending will play a key part. Here are two stocks I think will fall much further, and one that will fare far better than most.
On the surface, Oracle (NYSE: ORCL) looks incredible. Sales for its Oracle Cloud Infrastructure (OCI) arm -- the part building and leasing huge AI data centers -- jumped 121% to $7.4 billion in its most recent quarter. The company's remaining performance obligations (RPO) -- contracted revenue for services it hasn't delivered yet -- reached an incredible $664 billion.
But nothing is free, especially in the data center business. Oracle has to actually build the capacity to deliver on those contracts, and that takes a whole lot of cash. Oracle's free cash flow (FCF), the money left over after running the business and paying for things like construction and hardware, was negative $5.4 billion in the latest quarter.
That's a serious shortfall, and it comes even after a program of cost-cutting and significant layoffs.
To fund the difference, Oracle has turned to the debt market. At the end of August, it had $125 billion in long-term debt, plus $288 billion in data-center lease commitments that had not yet begun and aren't yet on its balance sheet.
Oracle is currently spending $1.4 billion every quarter on interest alone. The cash it earns from its operations is $23.1 billion.
While its mix of customers has expanded, Oracle is heavily dependent on a single customer that is, in turn, in a tenuous financial position: OpenAI. The ChatGPT maker is committed to spending $300 billion during the next five years, and as of its latest leaked financials, it had a loss of $12.3 billion last quarter.
That means a serious portion of Oracle's RPO relies on a company that could have trouble paying.
CoreWeave's (NASDAQ: CRWV) issues mirror Oracle's. The difference is in scale, and the fact that if providing AI compute doesn't turn out to be fabulously lucrative, Oracle still has a $24.5 billion software business (and a $15.9 billion cloud applications business). CoreWeave does not.

The company is a neocloud, and its entire model -- renting out Nvidia chips to AI customers -- relies on AI to continue booming. If AI demand slips, the company could be in serious trouble.
Of course, CoreWeave's top-line growth is incredible. Just look at the chart below.

Just as with Oracle, I'm wary of what that growth costs. CoreWeave had $35.6 billion in total debt at the end of June against just $5.5 billion in cash. Interest expense alone was $640 million for the quarter, and just recently, it completed another $4.2 billion convertible debt offering.
Berkshire Hathaway (NYSE: BRKB) (NYSE: BRKA) is absolutely a stock I'd want if things turn south.
Even after the recent departure of legendary Chief Executive Officer Warren Buffett, Berkshire is built to handle major market turmoil -- and profit from it. Berkshire had about $365 billion in cash and U.S. Treasury bills at the end of June. That's capital it can deploy during a market decline, buying good companies at a discount -- exactly what it did during the 2007-2009 financial crisis.
To be fair, the relatively defensive nature of Berkshire has a cost: The stock usually lags behind the market during major rallies. However, the reverse is true during major sell-offs.
