GoKawiilCNBC Investing Club portfolio splits as AI selloff hits Micron, lifts Cardinal Health
CNBC's Investing Club reports that its 32-stock portfolio has diverged sharply over the past five weeks, with AI-exposed names like Micron among the week's biggest losers and defensive stocks such as Cardinal Health among the top gainers. Since the group's Sept. 10 meeting, the Nasdaq is up 2.3% overall even as the Dow fell nearly 1%, while this week alone the Nasdaq dropped 2.5% amid a hot inflation report and renewed AI-stock weakness. CrowdStrike and Meta Platforms were cited as standout winners, up 19.4% and 14.4% respectively, driven by cybersecurity demand and AI-related product momentum.
GoKawiil's interpretation of the reporting above, not reported fact.
The split suggests investors are growing wary of how much debt-funded AI infrastructure spending companies can sustain if interest rates stay elevated, which could pressure highly leveraged AI plays like Micron further. Rotation into defensives such as Cardinal Health may indicate broader risk-off sentiment rather than a rejection of AI as a long-term theme. The Investing Club's framing implies that stock selection within the AI trade—rather than broad exposure—may matter more as rate-hike expectations persist.
- Micron was among the portfolio's biggest losers this week amid AI-trade anxiety, while Cardinal Health was a top weekly gainer.
- Since Sept. 10, the Nasdaq rose 2.3% overall despite this week's 2.5% weekly drop, while the Dow fell nearly 1%.
- CrowdStrike (+19.4%) and Meta Platforms (+14.4%) were the portfolio's standout winners over the five-week period, tied to cybersecurity demand and AI product launches.
