Nvidia shares closed at $221.30 on Monday, down $7.22 or 3.16%, as the semiconductor sector faced a broad selloff triggered by hotter-than-expected September inflation data. 

The decline pulled the stock further from its 52-week high of $243.37, with the chipmaker’s market capitalisation settling near $5.51 trillion after its steepest single-session loss in over a month.

Orminda analyst team gives a full breakdown of the technical and fundamental factors behind the pullback, and assesses whether the AI spending narrative remains intact despite mounting macroeconomic headwinds.

Sector-Wide Pressure Hits Chipmakers

Nvidia did not fall alone on Monday. Advanced Micro Devices shed 5.73%, Micron Technology dropped 4.10%, and Taiwan Semiconductor Manufacturing declined 3.40%. 

The Philadelphia Semiconductor Index lost roughly 3.5% on the session, marking its steepest single-day decline since August and dragging the broader technology sector lower.

The catalyst was September’s CPI report. Headline inflation printed at 3.7% year-over-year versus 3.6% expected, while core CPI registered 2.6% against 2.5% consensus. 

The data lifted Treasury yields, with the 10-year note climbing to 5.27%, increasing the discount rate applied to future earnings and making risk-free returns more competitive relative to high-multiple growth names.

Semiconductor stocks are particularly sensitive to rising yields because their valuations incorporate substantial future revenue growth. 

When the cost of capital increases, the present value of those future cash flows declines, compressing price-to-earnings multiples across the sector regardless of company-specific fundamentals.

AI Demand Meets Valuation Scrutiny

Nvidia’s fundamental story remains anchored by extraordinary demand for AI accelerators. CEO Jensen Huang recently noted that supply of the company’s next-generation Blackwell architecture remains “very tight,” with hyperscaler orders extending well into 2027. 

Data centre revenue continues to grow at triple-digit year-over-year rates, driven by enterprise adoption of large language models and generative AI workloads.

At $221.30, however, the stock trades at roughly 35 times forward earnings estimates, a premium that requires continued flawless execution and leaves limited room for disappointment. 

Any softening in order visibility or margin guidance would likely trigger a sharper re-rating than what Monday’s macro-driven selling produced.

The competitive landscape is also evolving. Microsoft’s announcement of its in-house Maia 300 AI chip added a secondary concern about potential demand diversification among major cloud customers.

While custom silicon efforts from hyperscalers are unlikely to displace Nvidia’s GPU platform entirely, they introduce an additional variable that the market will increasingly price into forward multiples.

AMD’s gains in the data centre GPU segment present another consideration. The company’s MI350 accelerator has attracted interest from cost-conscious enterprise buyers. 

Its expanding software ecosystem has narrowed Nvidia’s competitive moat in certain inference workloads, even as training demand remains firmly in Nvidia’s favour.

Technical Levels and Near-Term Outlook

Nvidia’s decline brought the stock to test the $218 support level, which aligns with the 50-day moving average. A break below that zone would open a clear path toward $205, where the August consolidation low sits and where buyers have previously stepped in to defend the longer-term uptrend.

Resistance stands at $230, a level the stock failed to hold during last week’s session. A sustained move above $235 would be needed to re-establish the uptrend that carried shares from their September lows and to bring the $243 record high back into range.

The 14-day RSI has fallen to 41, neutral territory that offers limited directional conviction. Volume on Monday’s decline was 12% above the 20-session average, suggesting the selling carried participation rather than representing thin-market noise.

The options market tells a similar story. Implied volatility on one-month Nvidia contracts rose to 38% from 33% the prior week, pricing in elevated uncertainty ahead of the quarterly reporting window. The put-call ratio climbed to 0.85, its highest reading since August, suggesting that hedging activity has picked up as the earnings date approaches.

Nvidia’s next quarterly report, expected in late November, will test whether guidance on Blackwell shipment timelines and margins can reignite buying interest or deepen the current pullback. Revenue consensus sits at $45 billion for the quarter, and any shortfall in data centre growth rates would be met with an outsized market reaction given the premium embedded in the stock.

Nvidia’s retreat reflects a market repricing growth-stock valuations against persistent inflation and rising yields. The structural AI spending cycle remains supportive, but the stock’s premium demands sustained revenue acceleration, and the coming earnings season will serve as the proving ground for that thesis.
