The 2026 "AI Bifurcation" – Lessons from the Feb 11 US Market Shift

[Vianne Mercer]

Hi everyone, I’m a CFA charterholder currently based in New York, and I wanted to share some observations from the US tape that might impact those of us managing global/cross-border portfolios.
Yesterday (Feb 11), we saw something very specific: a "shifting of gears." While the S&P 500 remained relatively flat at 6,941.47, the internal volatility was high. We are moving from a market where "AI" is a universal win to one where we look at "AI Disruption Risks."
Specifically:

• Infrastructure is still King: Cisco ($CSCO) showed strong AI demand with $15.35B in revenue.
• Application Pressure: Unity Software ($U) plummeted nearly 30% intraday as its Q1 guidance of $480M-$490M disappointed.

For those of us tracking the 10-year yield (now at 4.178%), it’s a reminder that "higher for longer" means we can't hide in hype anymore. We need companies with real credit durability.
I’d love to hear how the local community is adjusting their US tech exposure this month.
