Mumbai, July 7: US stock markets delivered a mixed performance in Tuesday’s opening session, with technology stocks bearing the brunt of a broad semiconductor sell-off triggered by Samsung Electronics’ quarterly results, while the Dow Jones Industrial Average reached a fresh all-time high.
The Nasdaq Composite (^IXIC) tumbled 264.72 points, or 1.01%, to trade at 25,856.44, extending Monday’s recovery losses. The S&P 500 (^GSPC) declined 25.91 points, or 0.34%, to 7,511.52, while the Dow Jones Industrial Average (^DJI) bucked the trend, edging up 5.71 points, or 0.01%, to 53,061.62, having earlier touched an intraday record of 53,289.30.
Trading volumes reflected cautious sentiment, with the Nasdaq recording 1.54 billion shares and the S&P 500 seeing 343.5 million shares exchanged within the first hour.
Samsung 19-Fold Profit Jump Erases $80 Billion Market Value as AI Spending Fears Resurface
The primary catalyst for Tuesday’s tech rout originated in Asia, where Samsung Electronics (005930.KS) reported a staggering 19-fold increase in second-quarter operating profit to 89.4 trillion won ($58.44 billion), surpassing an LSEG SmartEstimate of 87.3 trillion won and exceeding its combined earnings over the past three years. Revenue was projected to surge 129% year-on-year to 171 trillion won.
Despite smashing earnings expectations, Samsung shares plummeted as much as 10.1% in Seoul before closing 6.92% lower at KRW 68,256, wiping out more than $80 billion in market capitalisation. The sell-off stemmed from investor anxiety over whether US tech giants would sustain their massive artificial intelligence infrastructure spending, potentially curbing future memory chip demand.

Rival SK Hynix (000660.KS) dropped 6%, while South Korea’s KOSPI index tumbled 4.9%, briefly triggering a trading halt after an 8% decline earlier in the session. Samsung’s US-based suppliers also felt the impact, with Lam Research and Applied Materials slipping about 3.7% each in premarket trading.
Semiconductor Bloodbath: Applied Materials Plunges 10%, Intel and AMD Shed Over 7%
The negative sentiment cascaded across US chip stocks during Tuesday’s opening hour, with the VanEck Semiconductor ETF (SMH) falling more than 3%. Among the worst-hit Nasdaq-100 components, Applied Materials (AMAT) led the decline, plunging 10.02% to $536.96, followed by Lam Research (LRCX) which dropped 8.57%, and KLA Corporation (KLAC) which fell 7.94%.

Rivian Slides 13.6% After $1.5 Billion Share Sale and Preliminary Q2 Revenue Figures
Electric vehicle maker Rivian Automotive (RIVN) experienced a sharp decline of 13.60% to $17.40 after announcing a public offering of 75 million shares to raise $1.5 billion for general corporate purposes, including equity contributions for a Department of Energy loan.
The company reported preliminary second-quarter revenue of $1.55 billion to $1.65 billion, up from $1.3 billion a year earlier. A previous version of this blog post misstated Rivian’s preliminary second-quarter revenue forecast. The share sale comes after a hot streak, with Rivian’s stock rising 28% over the previous five trading sessions.
The offering, conducted during extended hours, drew investor scrutiny amid concerns over dilution.
SpaceX Joins Nasdaq-100 Amid Bullish Calls; Morgan Stanley Sets $300 Price Target
Space Exploration Technologies Corp (SPCX) officially entered the Nasdaq-100 index on Tuesday, marking a significant milestone for Elon Musk’s space and AI company. The stock traded 3.70% lower at $154.49, though it had initially opened flat. Despite the decline, Wall Street responded with a flurry of bullish analyst initiations: Morgan Stanley set a price target of $300 on the shares, while Raymond James also initiated coverage with a positive rating.
Wedbush issued an outperform rating with a $190 target. The inclusion means index-tracking funds, including the Invesco QQQ Trust (QQQ), must purchase SpaceX shares and trim other holdings to maintain benchmark alignment. BlackRock launched the iShares Nasdaq 100 ETF (IQQ) on Tuesday with an expense ratio of 0.12%, challenging Invesco’s dominance. SpaceX’s market cap stood near $2.1 trillion at yesterday’s close, though the stock remains 29% off its record high of $225.
This is likely to be the last high-profile index addition for SpaceX for a while, though it may yet become a member of the benchmark S&P 500 someday. The first of a series of SpaceX lock-up expirations lands on the second full trading day immediately following the company’s first earnings release date, expected in late July or early August.

The 10-year Treasury yield rose to 4.5%, while the 30-year yield stood at 5.01%, gaining 0.32% on the session.

In a first-of-its-kind event, US President Donald Trump rang the opening bells for the New York Stock Exchange and the Nasdaq from the Oval Office, marking the launch of the Trump Accounts programme aimed at encouraging long-term investing among American children.
The symbolic ceremony comes as Trump continues to spotlight the stock market as a barometer of the US economy ahead of the November mid-term elections. US Treasury Secretary Scott Bessent stated that the initiative seeks to expand participation in equity markets by increasing access for households that currently have little or no direct exposure to stocks. “38% of American families do not have any exposure to our great equity markets, but with Trump Accounts, over time, we can get that number to zero,” Bessent said.

The Dow’s record high indicates continued rotation into defensive sectors and value stocks. Oil prices above $69 per barrel amid Middle East tensions suggest heightened geopolitical risk premium.
