Nasdaq Composite rebounds over 2% as chip stocks shrug off last week’s AI rout

The Nasdaq Composite rose more than 2% on Monday, and the Nasdaq-100 climbed 3%, as bargain hunting across beaten-down semiconductor counters brought Wall Street back from last week’s AI rout. The Dow added around 800 points while oil slid, and technology stocks outside Nvidia did the lifting.

That combination tells you most of the week’s story. The tech-heavy Nasdaq Composite had logged a 3.4% weekly loss by Friday’s close, then bounced as chip stocks rallied. The index measures more than 2,500 stocks listed on the Nasdaq exchange, but its direction is overwhelmingly set by a small cluster of giant technology and semiconductor names. When those names fall hard, the whole index follows, because their market values carry enormous weight in the calculation.

What the Nasdaq Composite actually measures

The Nasdaq Composite is a market-capitalisation-weighted index. A stock priced higher and with more shares outstanding moves the index more than a small company would. That is why the index can leap 2-3% on a single day when a handful of large technology names recover together.

The Nasdaq-100 is the narrower, better-known cousin: the 100 largest non-financial companies on the exchange, again weighted by size. On Monday it rose about 3%, a stronger gain than the Composite’s roughly 2%, because the biggest tech names were at the front of the rebound. For instance, chip stocks broadly rallied while Nvidia lagged. The divergence between “tech outside Nvidia” and Nvidia itself became the market’s main dividing line.

Neither index reflects the whole US economy. They tilt heavily towards technology, consumer internet names and semiconductor makers. The Dow Jones Industrial Average, by contrast, is price-weighted and tracks 30 large industrial and financial companies, which is one reason it can add 800 points on the same day the Nasdaq is being dragged by a single stock like Nvidia.

What drove the rebound

The bounce came after what traders and commentary have described as an AI rout during the prior week. The selling had been concentrated in semiconductor and artificial-intelligence-linked stocks, and Friday’s session showed the first serious bargain hunting in exactly those counters. The Nasdaq Composite mounted only a partial recovery by the Friday close, leaving the index down 3.4% for the week.

On Monday the rebound widened. Seeking Alpha reported that both the Nasdaq-100 and the Nasdaq Composite advanced more than 2%, with the Nasdaq-100 up 3%. Reuters noted that Wall Street was set to open higher after the rout, and that Nvidia was still trading lower. CNBC’s coverage pointed to tech stocks outside Nvidia gaining while oil fell, and to an 800-point Dow rally.

The pattern is clear from those details: money rotated back into beaten-down chip stocks and other technology names, but it was not yet flowing back into the one stock most associated with the AI trade. Demand for oil weakened at the same time, and lower oil prices often take pressure off consumer and transport costs, which helps industrial-heavy measures like the Dow more than a pure tech index.

How Nvidia fits in

Nvidia is not inside the Nasdaq Composite by accident; it is one of the index’s largest and most influential components. A fall in Nvidia alone can drag the index down even when hundreds of other stocks are flat. The headlines from this stretch make that visible: the market managed a solid rebound on Monday only while Nvidia stayed under pressure, with the CNBC update explicitly framing the day’s gains as coming from tech stocks outside Nvidia, and Reuters calling Nvidia’s weakness a fresh test for the market’s floor.

That is the mechanical reality of a capitalisation-weighted index. Nvidia’s size means its gain or loss is amplified across the whole benchmark. Other large-cap technology names gained on Monday, but without a recovery in Nvidia the Nasdaq Composite’s comeback was partial and the market’s overall tone stayed cautious, as Friday’s mixed close had already suggested.

What to watch from here

The key question is whether the buying in semiconductor stocks can hold without a recovery in Nvidia. The index’s own structure suggests the two cannot stay apart for long. If chip stocks keep bouncing while Nvidia stays weak, the Nasdaq Composite will keep clawing back ground unevenly, driven by the rest of the technology complex rather than the AI trade itself.

Oil prices matter too. They fell alongside this week’s rebound, and the Dow’s 800-point move shows how falling oil can support a broader, industrial-weighted measure even when a tech index is still recovering from a selloff. Traders will be reading each new session for two signals together: whether semiconductor bargain hunting continues, and whether Nvidia stabilises. Those two outcomes will decide whether the Nasdaq Composite’s rebound turns from a one-day catch-up into something steadier.
