Stock Market Today ( Sept. 21, 2026 ): Nasdaq Jumps nearly 600 Points as AI and Chip Stocks Power Broad Monday Rally -( $DOCS EPRX $HPP $LPL $MODD $NVDA $SER $TE $TSLA $YSG )

U.S. stocks closed sharply higher on Monday, September 21, 2026, led by a powerful rally in technology, artificial intelligence, and semiconductor shares. The Nasdaq Composite climbed 2.26% to 27,125.09, while the S&P 500 gained 1.49% to finish at 7,764.70 and the Dow Jones Industrial Average rose 0.71% to 52,048.83. The risk-on session was reinforced by lower oil prices, stable volatility, continued strength in Bitcoin, and renewed investor enthusiasm for AI infrastructure spending. The rally also came as investors positioned ahead of high-level U.S.-China discussions later this week and assessed what easing energy prices could mean for inflation, Treasury yields, and the Federal Reserve’s next policy decisions.

U.S. Market Performance

The Nasdaq’s nearly 600-point advance marked the day’s standout move, reflecting powerful demand for AI-linked growth stocks. The S&P 500’s 1.49% gain showed that the rally extended beyond a narrow group of mega-cap names, although technology clearly set the pace. By comparison, the Russell 2000’s 0.56% gain suggested that small-cap participation remained more restrained amid still-elevated financing costs and uncertainty about the interest-rate outlook.

AI and Semiconductor Stocks Drive Leadership

Monday’s market advance was centered on artificial intelligence, data-center infrastructure, and semiconductor demand. Advanced Micro Devices, Inc. (AMD), Intel Corporation (INTC), and Arm Holdings plc (ARM) were among the notable beneficiaries as investors renewed their focus on the multi-year spending cycle for AI compute, networking, data centers, and advanced processors. The semiconductor group’s outperformance reinforced a key theme for equity markets: investors remain willing to pay for companies positioned to supply the hardware and software backbone of AI adoption. That includes chip designers, foundry and equipment suppliers, network-infrastructure companies, cloud providers, and enterprises building proprietary AI tools. Major technology and AI-linked public companies that remain central to this market theme include:

• NVIDIA Corporation (NVDA)
• Advanced Micro Devices, Inc. (AMD)
• Intel Corporation (INTC)
• Arm Holdings plc (ARM)
• Broadcom Inc. (AVGO)
• Microsoft Corporation (MSFT)
• Alphabet Inc. (GOOGL)
• Amazon.com, Inc. (AMZN)
• Meta Platforms, Inc. (META)
• Tesla, Inc. (TSLA)
• Oracle Corporation (ORCL)
• Palantir Technologies Inc. (PLTR)

Meta Platforms, Inc. (META) was also in focus as investors anticipated the company’s Connect event and evaluated the revenue potential of its artificial-intelligence products, digital-advertising tools, consumer devices, and AI-agent initiatives.

Macro Commentary: Lower Oil Supports Risk Appetite

The most consequential macro move of the session may have been the decline in crude oil. Crude closed near $92.21 per barrel, down $3.87, or roughly 4.03%, which offered investors relief after energy prices had become a central source of inflation concern. Oil-price declines can influence markets in several ways:

• Lower fuel and transportation costs can ease pressure on consumers and businesses.
• Cheaper energy can reduce the risk that headline inflation accelerates.
• A lower inflation threat can reduce pressure on bond yields.
• Falling yields can support growth-stock valuations, particularly AI and technology companies with earnings expected further in the future.

The market’s reaction was consistent with that framework. Technology and semiconductor shares rallied, gold declined 0.94%, and Bitcoin advanced more than 7%, signaling an investor preference for higher-risk and higher-growth assets rather than traditional defensive positioning. However, investors should avoid assuming that one day of lower oil prices resolves the broader inflation debate. Energy markets remain sensitive to geopolitical developments, supply disruptions, shipping constraints, OPEC+ policy, Russian export dynamics, and the outlook for global demand. A sustained move lower in oil would be more meaningful for inflation expectations than a single-session retreat.

Rates, Volatility, and Fed Outlook

The VIX finished essentially unchanged at 14.82, rising just 0.01 point, or 0.07%. That low-volatility reading suggests investors viewed Monday’s rally as constructive rather than fragile, even as the market faces major questions around Federal Reserve policy, Treasury yields, trade negotiations, and energy prices. Treasury yields moved lower during the session, providing an additional tailwind for equities. Lower long-term yields are especially important for high-growth sectors because they reduce the discount rate applied to expected future earnings. That dynamic tends to support companies such as NVIDIA Corporation (NVDA), Microsoft Corporation (MSFT), Alphabet Inc. (GOOGL), Meta Platforms, Inc. (META), and Amazon.com, Inc. (AMZN), whose valuations are closely tied to long-term growth expectations. The Federal Reserve remains a central market risk. Investors will be listening closely to policymakers for clues on whether they view recent energy-price pressure as a temporary shock or a factor that could keep inflation above target for longer. The market’s current preference for growth assets will be easier to sustain if inflation moderates, yields remain contained, and the Fed can avoid a more aggressive tightening path.

Bitcoin and Crypto Stocks Rally

Bitcoin climbed 7.01% to $86,759.03, a move that aligned with the broader improvement in risk appetite. The cryptocurrency’s advance also supported interest in publicly traded companies with exposure to digital assets, trading volumes, stablecoins, custody, and blockchain infrastructure. Crypto-sensitive stocks investors may watch include:

• Coinbase Global, Inc. (COIN)
• Robinhood Markets, Inc. (HOOD)
• Strategy Incorporated (MSTR)
• Marathon Digital Holdings, Inc. (MARA)
• Riot Platforms, Inc. (RIOT)
• CleanSpark, Inc. (CLSK)
• Circle Internet Group, Inc. (CRCL)

Bitcoin’s rise alongside the Nasdaq does not necessarily mean that the two assets will move together consistently. Still, Monday’s trading showed that both benefited from the same ingredients: a lower-volatility environment, improving risk sentiment, renewed interest in innovation-driven assets, and less immediate concern about oil-led inflation.

What Investors Are Watching Next

Monday’s rally improved near-term market sentiment, but investors will be focused on whether the move can broaden and persist.

• U.S.-China developments: Trade policy, tariffs, technology restrictions, semiconductor supply chains, AI governance, and critical-mineral access remain market-moving issues.
• Federal Reserve speeches: Policymaker commentary could shift expectations for rates, inflation, and Treasury yields.
• Energy-market direction: Further declines in oil could strengthen the disinflation narrative; a rebound could renew concern about consumer prices.
• AI spending and earnings: Investors will look for evidence that AI investment by hyperscalers and enterprises is translating into durable revenue and profit growth.
• Market breadth: The Nasdaq’s 2.26% jump was powerful, but the Russell 2000’s 0.56% gain indicates that mega-cap technology still carries disproportionate influence over index performance.
• Volatility: A VIX near 15 indicates calm market conditions, but that reading can change quickly around policy, geopolitical, or inflation-related surprises.

Bottom Line

U.S. markets delivered a strong risk-on close Monday, with the Nasdaq Composite rising 2.26% to 27,125.09, the S&P 500 advancing 1.49% to 7,764.70, and the Dow Jones Industrial Average gaining 0.71% to 52,048.83. The day’s leadership came from AI, semiconductors, and other growth-oriented assets, while the more than 4% drop in crude oil reduced an important near-term inflation concern. For investors, the next test is whether lower oil prices, easing yields, and AI-driven earnings expectations can support a broader advance. A sustained rally would likely require participation beyond large technology companies, continued moderation in inflation pressure, and greater clarity on Federal Reserve policy and U.S.-China trade relations.

Similarweb Ltd. (NYSE: SMWB)

Similarweb explores the many ways AI, apps, and other transformational forces are changing online shopping in its State of Ecommerce 2026 report, published on Sept 10. They reported that despite increasing more than 200% over the past year, direct referrals from dedicated AI platforms don’t produce a large volume of traffic to ecommerce marketplaces and online stores. In other words, compared with search, AI conversations don’t result in as much immediate click-through traffic. However, AI buying recommendations exert an outsize influence on purchases – in some cases, giving the recommended brand a 2-to-1 advantage over its competitors. Consumers are also making ChatGPT, Gemini, and other conversational AI tools a routine part of the buying process. However, that doesn’t mean they are abandoning search, 89% of the time, consumers who use AI in their shopping research also use search. “Consumers are not switching tools, they are stacking them,” said Daniel Reid, Principal Insight Analyst, Consumer Goods & Retail at Similarweb and the lead author of the report. “People are using AI to explore and narrow options while still turning to Search to move toward a decision. The most complex journeys, the ones that use both, convert the best. Retailers and brands who figure out how to master these new paths to product discovery stand to benefit.”

Similarweb Ltd. (NYSE: SMWB) and NIQ (NYSE: NIQ) have recently announced their planned Agentic Commerce Measurement solution aims to connect AI-based product discovery with consumer intent, traffic, conversion and verified sales outcomes. The first version is expected in the fourth quarter of 2026, initially across selected categories and markets. For many, the strategic appeal is simple: as AI becomes an increasingly consequential front door to commerce, the value may accrue not only to the companies building AI assistants, but also to the data-and-measurement providers that tell enterprises whether all that artificial intelligence is generating actual revenue, or merely very articulate window-shopping.

SMWB also recently delivered the sort of second-quarter report investors tend to enjoy: revenue and profitability exceeded guidance, full-year expectations moved higher, and AI demand translated into contracts rather than merely conference-call poetry. SMWB closed at $8.48, +3.04%. Learn More.

LG Display Co., Ltd. (LPL)

LG Display Co., Ltd. (NYSE: LPL, $3.04, +4.47%) has spent the last few years doing something many hardware companies talk about but few execute well: turning a technology pivot into a full‑blown business transformation that everyday investors can actually follow. Instead of chasing commoditized LCD TV panels in a race to the bottom, LPL is leaning into Gaming OLED, CES‑worthy innovation, and premium automotive displays – and the press trail tells a surprisingly investor‑friendly story.

Yatsen Group (NYSE: YSG)

Yatsen Group (NYSE: YSG, $2.61, +4.82%), a leading China-based beauty group, delivered the sort of quarter that can make a turnaround investor sit up straighter: reported revenue grew, its strategically important skincare operation accelerated sharply, and the company is increasingly built around clinical and premium brands rather than a pure color-cosmetics play. The results are not yet a victory lap, losses widened and third-quarter guidance is cautious, but YSG’s transformation is beginning to look less like a cosmetic touch-up and more like a genuine renovation.

YSG announced (July 8) a landmark collaboration to bring its flagship brand, Perfect Diary, to Sephora in China. This partnership integrates Yatsen’s rigorous scientific infrastructure with the world’s leading prestige beauty retailer, marking a significant milestone in Yatsen’s continuing evolution into a global beauty technology powerhouse.

Doximity is updating guidance for its fiscal year ending March 31, 2027 as follows:

• Revenue between $671 million and $681 million.
• Adjusted EBITDA between $309 million and $329 million.

Sable Offshore Corp. (SOC)

Sable Offshore Corp. (NYSE: SOC, $4.33) has moved from the awkward “pre-revenue restoration project” phase into something much more recognizable to Wall Street: a company selling meaningful volumes of oil, generating operating cash flow, and building momentum into a potentially larger 2027 earnings base. The second-quarter report on Monday was not a polished victory lap—midstream bottlenecks and one-time costs made sure of that—but it offered something potentially more valuable: proof that the Santa Ynez Unit restart is translating into barrels, revenue, and operational traction.

T1 Energy Inc. (NYSE: TE)

T1 Energy Inc. (NYSE: TE, $4.45, +6.71%) offers a different type of growth story: one rooted in domestic production, trade-policy tailwinds and execution on solar manufacturing capacity. T1 announced (Aug. 27) that local officials in Mo i Rana, Norway, have rezoned a portion of the company’s Giga Arctic campus, allowing for the development of a data center. T1 is pursuing multiple pathways to monetize this brownfield facility as part of a value optimization initiative.

T1 recently reported second-quarter net sales of $250.1 million, produced 935 megawatts of solar modules at its G1_Dallas facility and generated adjusted EBITDA of $10.7 million. The company also monetized $39.1 million of 2025 Section 45X tax credits and ended the quarter with $156.4 million in cash, cash equivalents and restricted cash, including $79.1 million unrestricted. The headline loss should not be ignored: T1 reported a $36.9 million net loss from continuing operations, while its adjusted EBITDA benefited from $24.4 million in tariff refunds recognized in cost of sales. Yet the more interesting investor question is whether the company is creating a viable U.S. solar-manufacturing platform at a time when supply-chain security and domestic energy capacity carry unusually high strategic value. The company expects its first solar cells from a planned 2.1-gigawatt manufacturing facility in the first quarter of 2027. With 3 gigawatts of firm contracts, a 641-megawatt offtake agreement with Clearway and 2026 output expected toward the upper end of its 3.1-to-4.2-gigawatt range, T1’s story is increasingly about turning production capacity into contracted revenue. For investors, TE is less a conventional earnings multiple story than an execution-and-optionality story. If domestic solar demand remains durable and manufacturing milestones stay on schedule, the market may ultimately value the company less like a troubled commodity producer and more like a strategically positioned industrial platform.

Nvidia (NVDA, $227.38, +2.30%)

NVDA announced plans (Sept. 3) to acquire open-AI platform Hugging Face for approximately $13 billion, with closing expected in 2027. The move reinforces NVIDIA’s effort to deepen its position across AI infrastructure, development tools, and the open-source AI ecosystem. Learn More.

Nvidia once again delivered (Wed., August 26) results that made Wall Street’s estimates look rather conservative. After the bell on Wednesday, NVIDIA, for its fiscal second quarter, the AI-chip leader reported adjusted earnings of $2.22 per share, ahead of the $2.10 consensus forecast, while revenue reached $96.22 billion, comfortably above expectations of $92.17 billion. The performance underscores Nvidia’s central role in the global AI buildout, where demand for its computing hardware continues to turn ambitious data-center plans into exceptionally large purchase orders. In short: the company remains one of the market’s preferred ways to bet on artificial intelligence, and, judging by the numbers, the machines are still very much hungry.
