Tech Up, Recouping Some Losses, as AI Bubble Fears Percolate - Tech Roundup

Provided by Dow Jones Oct 23, 2026, 9:41:00 PM

Shares of technology companies rose, recouping a modicum of their hefty Thursday losses, as traders tried to assess whether a speculative bubble in artificial-intelligence stocks was popping.

Ahead of Thursday's rout, hedge-fund billionaire Ken Griffin said the AI bubble was a legitimate concern.

South Korean memory-chip maker SK Hynix scrapped plans for a major U.S. public offering of its flash-memory unit Solidigm, highlighting the deepening investor caution about AI investment despite robust demand for AI-related hardware.

CoreWeave shares fell as traders weighed signals from derivatives markets about the cloud-computing firm's ability to keep up with AI infrastructure debt.

Transparency is our policy. Learn how it impacts everything we do

Transparency is how we protect the integrity of our work and keep empowering investors to achieve their goals and dreams. And we have unwavering standards for how we keep that integrity intact, from our research and data to our policies on content and your personal data.

We’d like to share more about how we work and what drives our day-to-day business.

How we make money

We sell different types of products and services to both investment professionals and individual investors. These products and services are usually sold through license agreements or subscriptions. Our investment management business generates asset-based fees, which are calculated as a percentage of assets under management. We also sell both admissions and sponsorship packages for our investment conferences and advertising on our websites and newsletters.

How we use your personal data

How we use your information depends on the product and service that you use and your relationship with us. We may use it to:

Verify your identity, personalize the content you receive, or create and administer your account.
Provide specific products and services to you, such as portfolio management or data aggregation.
Develop and improve features of our offerings.
Gear advertisements and other marketing efforts towards your interests.

How we approach editorial content

Maintaining independence and editorial freedom is essential to our mission of empowering investor success. We provide a platform for our authors to report on investments fairly, accurately, and from the investor’s point of view. We also respect individual opinions––they represent the unvarnished thinking of our people and exacting analysis of our research processes. Our authors can publish views that we may or may not agree with, but they show their work, distinguish facts from opinions, and make sure their analysis is clear and in no way misleading or deceptive.

To further protect the integrity of our editorial content, we keep a strict separation between our sales teams and authors to remove any pressure or influence on our analyses and research.

Read our editorial policy to learn more about our process.
