Applied Materials, Inc. (ISIN US0382221051) stock came under renewed pressure in the latest completed session, with shares falling 7.1 percent to USD 424.21 on September 14, 2026, as investors weighed fresh calls to slow the development of frontier AI models and reassessed valuations across semiconductor equipment names according to GuruFocus.
AI slowdown calls weigh on Applied Materials stock
The latest slide in Applied Materials stock is part of a broader selloff in chip and chip equipment names after the chief executives of Anthropic, OpenAI and SpaceX publicly urged a deliberate slowdown in the development of frontier AI models, which investors read as a potential drag on near-term data center and AI infrastructure spending according to StockStory.
As HDFCSky reported on September 14, 2026, Applied Materials shares dropped 6.99 percent intraday alongside steep declines in Lam Research, Marvell Technology and other semiconductor names as the Nasdaq opened sharply lower, underscoring how sensitive equipment makers are to sentiment around AI capital expenditure.
According to CNYES on September 14, 2026, Applied Materials traded between an intraday high of USD 430.45 and a low of USD 419.60, closing at around USD 428 with a decline of more than 6 percent, before settling at USD 424.21 by the end of the session as cited in valuation analysis from GuruFocus.
Valuation stretched versus intrinsic value and 52-week high
The recent pullback has not yet erased the strong run-up in Applied Materials stock over the past year, and valuation metrics remain demanding. On September 14, 2026, Applied Materials closed at USD 424.21 per share, which GuruFocus calculates as 72.1 percent above its GF Value estimate of USD 246.43, implying that the stock is significantly overvalued versus this intrinsic value model.
From a market perspective, shares remain well below their recent peak. As MarketWatch noted on September 14, 2026, Applied Materials closed that day 42.65 percent below its 52-week high of USD 739.67, achieved on June 30, 2026, highlighting how the stock has already retreated sharply from its summer peak even before the latest AI-related volatility.
Market capitalization figures reflect the large scale of the company despite the recent correction. According to exchange-linked quote data summarized by Robinhood on September 14, 2026, Applied Materials was recently trading around USD 427.11 with an equity market capitalization of approximately USD 336.66 billion, placing it among the largest semiconductor equipment makers globally.
Recent earnings and guidance support long-term AI and foundry demand
The share price moves come against the backdrop of strong fundamental results from Applied Materials in its most recent reported quarter, which investors continue to weigh against the new macro and policy uncertainties. As TechGraph reported in an overview of record fiscal third-quarter figures published in mid-September 2026, Applied Materials delivered record revenue and earnings in fiscal Q3 2026, reflecting robust demand from leading foundries and logic customers tied to AI and advanced node investments.
In that fiscal Q3 2026 report, Applied Materials guided next-quarter revenue to roughly USD 8.10 billion, while peer Lam Research projected about USD 10.25 billion, according to a comparative analysis of the two equipment makers published by 24/7 Wall St on September 15, 2026.
The same analysis from 24/7 Wall St emphasized that Applied Materials, with its broad exposure to deposition, etch and process control tools, serves as a defensive play on the same AI capital expenditure theme compared with some more specialized peers, suggesting that even if AI capex growth moderates, the company could still benefit from secular trends like node migration and wafer capacity expansions.
Investors now face the task of reconciling these strong underlying fundamentals with the elevated valuation signals from intrinsic value models. On one hand, record fiscal Q3 revenue and guidance around USD 8.10 billion for the following quarter underscore that Applied Materials is still executing well operationally in 2026. On the other hand, the GF Value metric showing the shares trading 72.1 percent above an estimated intrinsic value of USD 246.43 points to limited margin of safety at current prices, particularly if AI-related demand or broader macro conditions were to soften.
Analyst and intrinsic value perspectives on Applied Materials
The pullback has also reignited debate among analysts and valuation-focused investors about how much growth is already priced into Applied Materials stock. As GuruFocus highlighted on September 14, 2026, the GF Value framework still categorizes AMAT as significantly overvalued, with a negative margin of safety of 72.1 percent when comparing the market price of USD 424.21 to the GF Value line at USD 246.43.
By contrast, equity market commentators see Applied Materials as a relative safe haven within the AI capex complex. In the Lam Research versus Applied Materials comparison dated September 15, 2026, 24/7 Wall St noted a preference for Applied Materials as a more defensive way to gain exposure to ASML-linked AI capital expenditure themes, citing the breadth of its product portfolio and customer base.
For investors, the divergence between intrinsic value estimates and growth-oriented narratives means that position sizing and time horizon become key. Those relying on valuation models like GF Value will see the current 72.1 percent premium over intrinsic value as a warning signal, whereas growth investors may focus more on the record fiscal Q3 performance, next-quarter revenue guide around USD 8.10 billion, and the company’s central role in enabling advanced AI and logic nodes at leading foundries.
Stock remains volatile after earnings as macro risks build
Short-term volatility in Applied Materials stock has picked up since its mid-August fiscal Q3 2026 earnings release, with the share price swinging between the USD 400 and USD 450 range in recent sessions as investors digest both company-specific and macro-level news. As noted in market coverage that compiled Nasdaq-linked data through TechGraph, Applied Materials recently closed at USD 456.49 on September 14, 2026 with a modest daily gain of 0.55 percent before the later valuation commentary from GuruFocus referenced the lower USD 424.21 closing price, underscoring rapid intraday and cross-venue fluctuations.
Broader sector moves add to the uncertainty. The same HDFCSky report that listed a 6.99 percent drop for Applied Materials on September 14, 2026 also cited declines of more than 7 percent in Lam Research and Marvell Technology and notable weakness in other chip names such as Arm Holdings, KLA Corporation and Qualcomm, illustrating that the AI slowdown narrative combined with USD 110 oil prices has become a cross-sector macro risk factor for high-valuation technology equities.
From a technical perspective, the fact that Applied Materials now trades more than 40 percent below its 52-week high of USD 739.67, while still sitting over 70 percent above one widely followed intrinsic value estimate, highlights the tension between momentum unwinds and still-elevated expectations. For investors tracking support and resistance levels, the USD 400–USD 430 band has emerged as a key near-term trading zone following the September 14, 2026 selloff.
Applied Materials stock price and key figures
As of the most recent completed trading day referenced in valuation commentary, on September 14, 2026 Applied Materials stock closed at USD 424.21 on Nasdaq, down 7.1 percent for that session, based on market data summarized by GuruFocus.
On the same date, the shares stood 42.65 percent below their 52-week high of USD 739.67 reached on June 30, 2026, according to performance data cited by MarketWatch, providing a concrete measure of how far the stock has fallen from its recent peak.
Market capitalization around USD 336.66 billion at a share price near USD 427 on September 14, 2026 as reported by Robinhood underscores that Applied Materials remains a heavyweight in the semiconductor equipment space even after the recent volatility. For investors, these figures frame the balance between strong fundamentals and valuation risk as they consider the stock’s role in their portfolios.
