It was a rough start to the fourth quarter for Technology stocks. In the week ending October 16, the Nasdaq Composite fell approximately 4.5%, as investors started to scrutinize borrowing costs associated with the AI infrastructure buildout.
In this week’s column, I’m going to reference specific companies to illustrate where some of the financing pressure was coming from. But please note, references to individual companies are for illustrative purposes only and are not recommendations to buy, sell, or hold any security.
The biggest company driving investor concern was CoreWeave, which provides cloud computing capacity for AI. The company had issued unsecured bonds in June with a 9.625% annual coupon, but by the end of last week, reports put yields on some of its bonds at roughly 15%–16%. Credit investors were demanding substantially greater compensation to own its debt. 1
The distinction between the coupon and market yield is important. Falling bond prices do not automatically increase interest payments on existing fixed-rate debt. They do, however, indicate the returns investors may require for future borrowing or refinancing.
CoreWeave’s quarterly results make this financing challenge tangible. Second-quarter revenue more than doubled to $2.58 billion, but the company reported $640 million in net interest expense and a $626 million net loss. Rising demand for CoreWeave’s services is coexisting with rising financing expense, which leaves less room for delays or disappointing returns.2
Over last weekend, Reuters reported that Anthropic was offering a yield exceeding 10% on a proposed $9 billion financing involving Blackstone funds, backed by five years of chip-lease payments. Anthropic is being held out as one of the most promising frontier labs, but 10% yields on $9 billion represents a substantial financing cost to carry as the investment generates returns.2
I think these financing risks warrant caution, particularly when a portfolio depends heavily on companies borrowing to fund rapid expansion. And even though it may seem like Technology is the only game in town, I think investors have a much wider range of businesses to consider—with different capital requirements and sources of profit. The latest earnings estimates give us a useful picture of those opportunities.
According to our colleagues at Zacks Investment Research, third-quarter S&P 500 earnings are expected to increase 24.6% year-over-year on 11.7% higher revenues. Removing Technology reduces expected earnings growth to 14.4%, but double-digit growth across the rest of the index is still an encouraging starting point.
The breadth is encouraging: 14 of the 16 Zacks sectors are expected to report positive earnings growth. And looking ahead, upward fourth-quarter revisions extend into Aerospace, Construction, Industrials, Finance, and Transportation. That gives investors evidence of improving profit expectations outside the companies at the center of the AI financing debate.
These are forecasts that incoming results will test, which we’ll of course be watching closely.

Valuations also differ substantially across the market. At the start of October, the equal-weight S&P 500 traded at approximately 15x expected earnings over the next 12 months, compared with about 19x for the traditional S&P 500 Index. That gap suggests investors can find stocks trading at more attractive valuations outside the market’s largest companies.
That leaves opportunities to evaluate growing businesses at more modest valuations. A lower multiple still requires scrutiny, but investors have a much wider set of choices than the handful of companies attracting the most headlines, in my view.
Going forward, the financing concerns deserve continued attention. A sustained reduction in AI investment could affect equipment suppliers and lenders beyond the borrowers themselves. I would become more concerned if those pressures began producing widespread earnings downgrades or making credit harder to obtain across unrelated industries. For now, the Zacks earnings outlook supports a broader search for opportunities. Investors can assess cash generation and valuations across sectors while keeping exposure to any single financing cycle (in this case, AI) in proportion.
Bottom Line for Investors
The recent selloff is a useful opportunity to examine how much of a portfolio depends on the same outcome. Several holdings can carry different company names while relying on the same capital-spending cycle.
In my view, diversification means giving a portfolio multiple ways to make progress. There is room to participate in AI, while also owning businesses with different customers, financing needs, and sources of profit. That flexibility becomes particularly valuable when one of the market’s most prominent growth themes faces a more demanding financial test, as we may be seeing now.
