According to BBC Business, artificial intelligence and technology stocks reversed a rout that wiped trillions of dollars from global equity values earlier in the week. The Nasdaq 100 climbed 1.39% to 26,999.40 by Friday trade, according to WealthWatchPro market data captured 6 November 2026, while the VIX volatility index fell 10.57% to 25.20 on the same session. The bounce followed investor concern that a Democrat victory in the US midterm elections would slow AI development through tighter regulation of data centres.

Chipmakers Lead the Snapback, Breadth Lags Behind

The sell-off that preceded Friday's rally was brutal and concentrated. Per the BBC report, Nvidia shed hundreds of billions in market value on Thursday as shares slid more than 9%, while AMD and Micron both dropped by more than 17%. The reversal on Friday was just as sharp in the same names: Nvidia opened up more than 6% before settling around 4% higher, AMD rose about 12%, and Micron gained more than 8%. Tesla and SpaceX shares, also hammered on Thursday, posted mixed gains of roughly 5% and 6% respectively.

What stands out is who did not fully participate. The Russell 2000 added only 0.74% to 2,750.19, and the Dow Jones Industrial Average slipped 0.09% to 51,475.23, according to WealthWatchPro market data from 6 November 2026. The S&P 500 rose a more modest 0.57% to 7,395.98. This is the signature of a narrow snapback rather than a broad risk-on move: capital flowed back into the exact handful of chip and AI megacaps that had fallen hardest, while the broader market, including small caps tracked by the Russell 2000, barely moved. That divergence is the clearest marker of sector rotation in this episode, and it argues the AI trade remains concentrated rather than genuinely diversified across market capitalisation.

Jobs Data Cushions the Blow, VIX Still Elevated

Timing helped the rebound. The BBC report notes US employers added 165,000 jobs in October, more than double what analysts had expected, while the unemployment rate eased to 4.1% from 4.2% in September. Neil Birrell, chief investment officer at Premier Miton, told the BBC the US economy is "running hard," which may mean the risks markets are worrying about are not as severe a threat to the real economy as feared. That framing gave investors a reason to look past the political overhang on AI spending, at least for one session.

"While no-one knows what happens next, it's clear that we've just seen a significant shift in market sentiment," said Dan Coatsworth, head of markets at AJ Bell, as reported by the BBC. "Once investors have had the weekend to catch their breath, next week could give a clearer indication of whether the tech trade is going down the pan or fighting back."

The VIX's 10.57% drop to 25.20 is meaningful but should not be read as calm restored. A reading in the mid-20s still sits well above the long-run average near 15 to 20 that has prevailed in quieter periods this year. The fear gauge easing from a spike, rather than returning to a low baseline, is consistent with a market that remains braced for further swings rather than one that has resolved its uncertainty.

Asia and Europe Show the Rotation Didn't Travel Evenly

Global indices diverged sharply on the same day. The Nikkei 225 fell 5.96% to 57,434.77, according to WealthWatchPro market data, echoing the BBC's report that South Korea's Kospi closed down 6% with chipmaker SK Hynix plunging more than 10%. By contrast, the Hang Seng rose 2.35% to 24,481.86 and the ASX 200 gained 2.11% to 9,020.80 on the same day. The Shanghai Composite slipped 1% to 3,649.18. European markets stayed broadly negative: the FTSE 100 fell 1.01% to 10,673.94, the DAX dropped 1.92% to 25,820.36, the CAC 40 declined 0.81% to 8,139, and the Euro Stoxx 50 lost 0.98% to 6,170.49.

This pattern matters for anyone thinking about sector rotation as a global phenomenon rather than a US-only story. Tech-heavy indices with direct semiconductor supply chain exposure, Japan and South Korea in particular, bore the brunt of the sell-off's hangover even as US chip names recovered. Meanwhile indices more tilted toward resources and financials, including the ASX 200 and Hang Seng, rallied. The rotation out of AI risk and back in was not a single global wave. It moved unevenly across markets depending on each index's underlying sector composition.

What This Means for Portfolio Positioning

WealthWatchPro's reading of this data set is that the AI trade's recovery has not yet broadened into the kind of durable, cycle-driven rotation that typically follows a genuine shift in economic conditions. Classic sector rotation moves between cyclical and defensive, or growth and value, based on where an economy sits in its cycle. This week's whipsaw was triggered by a political and regulatory headline, not by a change in earnings trajectories or the yield curve. That distinction matters because political-risk-driven rotations can reverse just as quickly as they appear, as Friday's bounce demonstrates.

With the Shiller CAPE at 38.79, according to WealthWatchPro data, US equity valuations sit well above long-run historical norms, a condition that tends to amplify single-day repricing when sentiment shifts. Investors watching breadth indicators, the gap between Nasdaq 100 and Russell 2000 performance in particular, have a practical early-warning tool for distinguishing a genuine rotation from a short squeeze in a handful of names. Readers can review the mechanics of breadth and momentum signals in our guide to Technical Analysis Basics.

Background: Sector Rotation in Context

Sector rotation describes how investors shift capital between sectors as economic conditions change, typically moving toward cyclicals early in an expansion and defensives as growth slows. Our full explainer on Sector Rotation covers the mechanics in more detail. The AI sell-off and rebound this week is an unusual variant: a rotation driven by a single political event rather than a macro turning point. Readers can explore historical valuation cycles in The History of Stock Markets, Part 3.

Markets will take direction from how AMD, Micron and Nvidia trade into next week, and whether the Russell 2000 starts closing the gap with the Nasdaq 100. Until breadth improves, treat this week's rebound as a rotation within AI leadership, not a resolution of the underlying question investors are asking about the sector.
