Nvidia's stock has dropped back below $200 a share after several days of heavy selling, an unusual stumble for a company that has powered the artificial-intelligence boom.

According to The Motley Fool, the stock had traded above $200 for a long stretch and is now down roughly 16% from its highs. Zacks Investment Research notes shares have fallen about 7% over the past month.

What makes the slide striking is that it comes while the rest of the chip sector is booming. According to Yahoo Finance and 24/7 Wall St., Nvidia is up just 3.2% for 2026 so far, making it a notable laggard even as money floods into rival chip stocks. The outlets go so far as to call Nvidia the "black sheep" of the chip-stock rally, pointing out that its fundamentals "have never looked stronger" even as the share price limps along.

One worry weighing on investors is the idea that Nvidia is losing market share to competitors. But according to Goldman Sachs, as reported by Barron's and MSN, that concern may already be baked into the price. Goldman argues the stock now looks cheap enough that its "bargain valuation" already reflects lost market share, and the bank sees reason to be optimistic, framing it as a buy.

Some commentators are looking past the dip entirely. The Motley Fool published an analysis titled around when Nvidia could climb to $300 a share, while acknowledging the recent pressure.

Why it matters: Nvidia is the most valuable name in the AI trade, so when its stock diverges from a rising chip sector, it raises a bigger question for ordinary investors — whether this is a rare buying opportunity or an early sign the AI-chip leader's dominance is being tested.
