Mumbai, July 20: Wall Street concluded Monday’s trading session firmly in negative territory, as a deepening selloff in artificial intelligence-driven semiconductor stocks and escalating geopolitical tensions with Iran extinguished earlier recovery hopes.

The tech-heavy Nasdaq Composite bore the brunt of the selloff, tumbling 12.17 points, or 0.05%, to close at 25,508.07. The broader S&P 500 lost 14.41 points, or 0.19%, settling at 7,443.28, while the Dow Jones Industrial Average shed 307.16 points, or 0.59%, to finish at 51,839.26.

The market’s sharp reversal came despite an early session rally, underscoring fragile investor sentiment as the second-quarter earnings season intensifies against a backdrop of global uncertainty.

S&P 500 and Nasdaq Erase Early Gains as Broad-Based Selling Intensifies

The session’s initial optimism, fueled by a recovery in chip stocks and easing oil prices, proved short-lived. The S&P 500 had climbed as much as 55.53 points at its session high, while the Nasdaq Composite rallied 295.36 points at its peak before both indices surrendered their advances and closed deep in the red. By the closing bell, ten of the 11 broad sectors of the S&P 500 ended in negative territory.

The Communication Services Select Sector SPDR (XLC) suffered the steepest decline, falling 2.4%, followed by the Consumer Discretionary Select Sector SPDR (XLY) which dropped 1.6%, and the Technology Select Sector SPDR (XLK) which slipped 1.1%. In contrast, the Energy Select Sector SPDR (XLE) advanced 1.2% as crude prices remained elevated.

The CBOE Volatility Index (VIX), Wall Street’s fear gauge, surged 12.2% to 18.77, reflecting heightened risk aversion among market participants. Trading volumes remained subdued, with 17.55 billion shares exchanged, falling below the 20-session average of 20.87 billion. Decliners significantly outpaced advancers, with a 1.94-to-1 ratio on the NYSE and a 1.76-to-1 ratio on the Nasdaq.

Iran Tensions and AI Pullback Trigger Sharp Risk-Off Sentiment

The market’s decline was driven by a confluence of negative factors, with geopolitical uncertainty and sector-specific weakness compounding investor anxieties. Renewed tensions involving Iran weighed heavily on sentiment, as the United States launched its ninth consecutive strike on Iran late Sunday.

Investors grew increasingly concerned that any escalation could disrupt global energy supplies through the Strait of Hormuz, stoke inflationary pressures, and impede economic growth. Brent crude prices responded by surging above $90 a barrel, while West Texas Intermediate (WTI) crude rose 1.96% to $84.16. Although comments from Iran suggesting a potential for diplomatic negotiations briefly eased oil prices, the underlying geopolitical risks kept a lid on risk appetite.

Compounding the external pressures, the sharp pullback in AI-related stocks triggered a broader wave of risk aversion across the market. The selling pressure, which began in semiconductor shares, rapidly spread to other growth-oriented sectors, including technology and consumer discretionary. After months of robust gains fuelled by AI enthusiasm, traders opted to lock in profits and reassess valuations, exposing the market’s vulnerability to a shift in confidence in the AI theme.

Dow Jones Industrial Average: 23 of 30 Components Close in the Red

The Dow Jones Industrial Average ended Monday at 51,839.26, recording a loss of 307.16 points or 0.59%. The blue-chip index’s decline was broad-based, with 23 of the 30 components finishing in negative territory.

Within the Dow, technology and consumer discretionary names were among the primary laggards. Nike (NKE) emerged as the session’s biggest loser, falling 1.49%, followed by Sherwin-Williams (SHW) which declined 1.29%, and Walt Disney (DIS) which dropped 1.14%.

On the positive side, Alphabet (GOOGL) advanced 2.77%, Nvidia (NVDA) climbed 2.39%, and Goldman Sachs (GS) gained 1.31%, providing some support to the index. The Dow’s weekly performance also remained under pressure, with the index slipping 0.9% over the past five trading sessions.

Nasdaq Composite Sheds 0.05% as Tech and Chip Stocks Bear the Brunt

The Nasdaq Composite, heavily weighted towards technology and growth stocks, plummeting 12. 17 points or 0.05% to close at 25,508.07. The index’s decline was driven by sustained weakness in semiconductor and AI-related names, which have been under significant pressure following last week’s sharp selloff.

The Philadelphia Semiconductor Index fell 1.6% to its lowest closing level in nearly two months, reflecting the extent of the damage in the chip sector. The VanEck Semiconductor ETF (SMH) had tumbled nearly 9% last week, and the bearish momentum carried into Monday’s session. The Nasdaq’s weekly losses were even more pronounced, with the index declining 2.9% over the past week, marking its worst weekly performance this quarter. The weakness in technology was further underscored by the Nasdaq-100, which returned -1.5% on the day.

Small-Cap Russell 2000 and Mid-Cap Indices Reflect Broader Weakness

The selling pressure was not confined to large-cap indices, as mid-cap and small-cap benchmarks also recorded losses. The Russell 2000 Index, which tracks the performance of small-cap companies, closed down 0.67% at 2942.43 points. The decline in the Russell 2000 suggests that risk-off sentiment permeated across market capitalisations, with smaller companies often perceived as more vulnerable to economic uncertainty and geopolitical shocks.

The S&P 400 Mid-Cap Index and the S&P 600 Small-Cap Index also registered declines, though specific closing figures were not immediately available. The broader weakness in these indices indicates that the market’s decline was not merely a technology-driven phenomenon but reflected a more widespread retreat from equities.

S&P 500 Top Gainers: Travelers Surges 9.2%, Seagate and Centene Follow

Despite the broader market decline, a select group of stocks within the S&P 500 managed to post significant gains. The Travelers Companies (TRV) emerged as the index’s top performer, surging 9.2% to close at elevated levels. The insurance giant’s sharp rally was attributed to its defensive characteristics, which tend to attract investors during periods of market turbulence.

Seagate Technology (STX) followed closely, advancing 5.7%, while Centene (CNC) gained 4.0%. Other notable gainers included Casey’s General Stores (CASY) , which rose 3.9%, Lumentum (LITE) which climbed 3.8%, and Humana (HUM) which added 3.5%. Archer-Daniels-Midland (ADM) and Allstate (ALL) each gained 3.5% and 3.3%, respectively, while American International Group (AIG) advanced 3.2% and Valero Energy (VLO) rose 3.1%. The outperformance of insurance, energy, and select consumer names reflected a defensive rotation within the index.

S&P 500 Top Losers: Intuitive Surgical Plunges 14.1% on Analyst Downgrades

On the losing side, Intuitive Surgical (ISRG) was the session’s most severe decliner, plummeting 14.15% to $345.42. The surgical robotics company’s shares came under intense pressure after multiple analysts cut price targets following its second-quarter results and indications of slower procedure growth.

The stock’s significant drop underscores the market’s heightened sensitivity to earnings disappointments and growth concerns in the healthcare technology sector. Coterra Energy (CTRA) followed as the second-largest loser, falling 8.62% to $32.56, while Synopsys (SNPS) declined 7.85% to $384.28. Honeywell Aerospace (HONA.OQ) dropped 5.4%, Carvana (CVNA.N) fell 4.3%, and Chipotle Mexican Grill (CMG.N) lost 3.9%. Intuit (INTU) also featured among the losers, trading down 3.4%. The decline in these names highlights the market’s rotation away from high-growth and momentum stocks towards more defensive positions.

NYSE Top Movers: AMC Entertainment Soars 22.2% on Surprise Q2 Profit

The New York Stock Exchange witnessed some extraordinary moves, particularly among speculative and recovery stocks. AMC Entertainment Holdings (AMC.N) emerged as the top percentage gainer on the NYSE, skyrocketing 22.2% after reporting a surprise second-quarter profit and record revenue.

The cinema chain’s impressive performance defied broader market weakness and highlighted the potential for selective recovery stories. Archer Aviation (ACHR.N) followed with a gain of 21.4%, while Vertical Aerospace (EVTL.N) advanced 13.2%.

On the losing side, System1 (SST.N) plunged 16.2%, Standard Nuclear (STDN.N) dropped 11.7%, and CNFinance Holdings (CNF.N) fell 11.0%. The sharp divergence in NYSE movers underscores the highly stock-specific nature of Monday’s trading action.

Nasdaq Top Movers: Zhengye Biotechnology Surges 314% in Volatile Session

The Nasdaq exchange witnessed even more extreme price swings, particularly among smaller and micro-cap names. Zhengye Biotechnology Holding (ZYBT.OQ) was the standout performer, surging an astonishing 314.0%. Global Mofy AI (GMM.OQ) gained 55.5%, while Advanced Biomed (ADVB.OQ) advanced 49.0%.

On the losing side, Li Bang International Corporation (LBGJ.OQ) collapsed 88.3%, Globavend Holdings (GVH.OQ) tumbled 70.0%, and Smart Powerr (CREG.OQ) plunged 47.6%. These extreme moves highlight the speculative nature of certain segments of the market, with low-float stocks experiencing outsized volatility.

Jersey Mike’s Subs Targets $7.94 Billion Valuation in US IPO

The initial public offering market remained active on Monday, with two notable companies announcing their intentions to go public. Sandwich chain Jersey Mike’s Subs announced its aim to raise as much as $1.09 billion in its U.S. initial public offering. The company, which traces its roots to 1956 in Point Pleasant, New Jersey, is targeting a valuation of up to $7.94 billion. Jersey Mike’s has applied to list on the New York Stock Exchange under the trading symbol “JMKE,” with Morgan Stanley, Jefferies, and J.P. Morgan serving as the joint book-running managers. The offering represents a significant test of investor appetite for consumer-facing brands in an IPO market that has been dominated by AI infrastructure and defence firms.

Reformation Targets $1 Billion Valuation in Rare Fashion Brand IPO

In another notable IPO development, Permira-backed womenswear retailer Reformation announced its target of a valuation of up to $1 billion in its U.S. initial public offering. The Vernon, California-based company said it and some selling shareholders aim to raise up to $239.1 million by offering 14.1 million shares priced between $15 and $17 each.

The IPO marks a rare foray into public markets for a fashion brand in recent years and could signal whether the market’s revival is broadening beyond today’s favoured sectors. Reformation intends to list its shares on the NYSE under the symbol “REF,” with J.P. Morgan, Morgan Stanley, Citigroup, and RBC Capital Markets among the underwriters.

Paramount Skydance’s $110 Billion Warner Bros. Acquisition Halted by Federal Judge

In a significant development in the media sector, a federal judge ordered Paramount Skydance to pause its $110 billion acquisition of Warner Bros. Discovery through August 3. The ruling came after a California-led coalition of states argued that the merger would irreparably harm competition. The temporary block prevents the media companies from finalising the transaction or consolidating their operations.

The decision is expected to weigh on Paramount Skydance Corp. (PSKY) shares, which are set to end at record lows following the ruling. The development underscores the increasing regulatory scrutiny on large-scale media mergers and could have broader implications for consolidation in the entertainment industry.

BOXABL Inc. Commences Trading on Nasdaq Following $3.5 Billion Merger

BOXABL Inc. (BXBL) commenced trading on the Nasdaq stock market on Monday, following the completion of its business combination with FG Merger II Corp. The combined company, valued at $3.5 billion, issued 350 million shares to BOXABL stockholders based on a deemed value of $10 per share.

The listing marks a significant milestone for the prefabricated construction technology company, which has attracted considerable investor interest in the sustainable housing sector.

The stock opened at $11.52, above its reference price, and traded between $9.89 and $11.99 during the session. The shares surged 20% during the company’s first trading session. It closed at $10.42, gaining $2.12 or 25.54% from the reference price. Trading volume reached 2.58 million shares, significantly above the 65-day average of 193,000 shares, with the company’s market capitalisation reaching approximately $1.15 billion. The strong debut came despite a 1.4% decline in Nasdaq Composite, highlighting investor interest in sustainable housing and construction technology.

Niki BioSolutions Begins Trading on Nasdaq Following Aptorum-DiamiR Merger

Niki BioSolutions, Inc. began trading on the Nasdaq Capital Market under the new ticker symbol “NIKI” on Monday, following the merger of Aptorum Group and DiamiR Biosciences. The combined entity’s shares commenced trading on a split-adjusted basis, marking the completion of the merger between the two biopharmaceutical companies.

The stock opened at $11.00 and traded between $9.56 and $12.24 during the session. . By the closing bell, the stock settled at $8.83, which represents a decline of $2.17, or 19.73%, from its opening price of $11.00. Trading volume stood at 215,900 shares, significantly above the 65-day average of 4,400 shares, while market capitalisation reached approximately $5.72 million. The strong debut reflected investor optimism around the company’s biosciences platform focused on diagnostics and therapeutics.

The listing represents a strategic move to consolidate operations and enhance the combined company’s visibility in the U.S. capital markets. The biotech sector has been a focal point for merger activity, and the Niki BioSolutions listing adds to the growing list of corporate actions in the space.

Ferguson Enterprises Cancels Secondary Listing on London Stock Exchange

Ferguson Enterprises Inc. announced the completion of the cancellation of its secondary listing on the London Stock Exchange’s main market, effective 8:00 a.m. U.K. time on Monday. The company, which maintains its primary listing of common stock on the New York Stock Exchange, confirmed that its shares are no longer admitted to trading on the London exchange.

The delisting decision reflects Ferguson’s strategic focus on its U.S. operations and follows a trend of companies streamlining their listing structures to reduce administrative costs and compliance burdens. The move is not expected to impact the company’s operational performance or its NYSE-listed shares.

CLINUVEL’s American Depositary Shares Commence Trading on Nasdaq

CLINUVEL Pharmaceuticals Limited announced the commencement of trading of its American Depositary Shares (ADS) on the Nasdaq Stock Market under the ticker symbol “CUVL” on Monday. The Australian Securities Exchange-listed company (ASX: CUV) secured the Nasdaq listing to enhance its visibility and accessibility to U.S. investors.

The upgrade to the Nasdaq represents an important step for CLINUVEL’s strategic expansion in the U.S. market and could potentially broaden its shareholder base. The biopharmaceutical company, which specialises in treatments for rare diseases, will continue to maintain its primary listing on the ASX.

Market participants should monitor the unfolding earnings season, with Alphabet, Tesla, and Intel reporting this week, which could provide crucial guidance on AI spending and corporate profitability. Geopolitical developments in the Middle East, particularly regarding Iran, remain a key risk factor that could influence energy prices and broader market sentiment. The CBOE Volatility Index (VIX) at 18.77 suggests elevated market uncertainty. Investors should remain vigilant about valuation concerns in the AI and semiconductor sectors, which have experienced significa;nt volatility.
