 Stock Market Today: Nasdaq Leads as Chipmakers Roar Back and Earnings Season Delivers

**Wall Street shook off geopolitical jitters and tariff turmoil on Tuesday, as a powerful rebound in semiconductor stocks and a string of better-than-expected corporate results lifted the major indexes. The Nasdaq Composite led the charge, climbing over 1% as investors positioned for a crucial week of Big Tech earnings that could define the AI trade for the rest of the year.**

### The Headline Numbers: A Tale of Two Markets

Stocks opened firmly in positive territory on Tuesday, July 21, 2026, with the technology-heavy Nasdaq Composite outperforming as chipmakers rallied for a second consecutive day.

*   **Dow Jones Industrial Average:** Rose about 212 points, or 0.4%, at the opening bell.

*   **S&P 500:** Advanced 0.6%.

*   **Nasdaq Composite:** Climbed over 1%, leading the major indexes.

The gains marked a sharp reversal from Monday's session, when the major indexes closed lower as escalating U.S.-Iran tensions overshadowed a positive start. By Tuesday, investors appeared to look past the latest geopolitical headlines, focusing instead on a revival in semiconductor stocks and a strong start to the second-quarter earnings season.

Futures had signaled the rebound earlier in the day. At 7:21 a.m. ET, Dow E-minis were up 155 points, or 0.3%, while S&P 500 E-minis were up 30.25 points, or 0.4%. The Nasdaq 100 E-minis led the advance, surging 346 points, or 1.2%.

### The Chip Rebound: Semiconductors Lead the Charge

The semiconductor sector, which had been battered by a brutal selloff that pushed the Philadelphia SE Semiconductor Index into a bear market, extended its recovery on Tuesday.

The iShares Semiconductor ETF (SOXX) climbed 4%, marking its second consecutive day of gains. The rebound was broad-based, with memory chipmakers leading the way:

*   **Micron Technology (MU):** Jumped 4.8% to 6.5%.

*   **SanDisk (SNDK):** Surged 6% to 8%.

*   **Marvell Technology (MRVL):** Rallied 6% to 7%, extending its winning streak to three sessions.

*   **Advanced Micro Devices (AMD):** Gained 4% in premarket trading.

*   **Intel (INTC):** Added 6% as investors anticipated its upcoming earnings report.

*   **Applied Materials (AMAT):** Rose 5%.

The rebound comes after the Philadelphia Semiconductor Index ended Friday more than 20% below its late-June record high, confirming a bear-market decline. Despite the recent volatility, the index remains up about 66% for the year, reflecting the powerful AI-driven rally that has characterized 2026.

The resurgence in chip stocks was fueled by several factors: bargain hunting after a steep selloff, positioning ahead of major tech earnings, and continued optimism about AI infrastructure spending. As one analyst noted, "While shipping confidence and oil production may take longer than expected to be fully restored, we expect limited pass-through to core inflation, keeping central banks from tightening aggressively. This means earnings growth should remain a key driver of the equity market".

### Earnings Season Delivers: 3M, GM Beat Expectations

The second-quarter earnings season continued to deliver positive surprises, providing a tailwind for the broader market. About 87% of early S&P 500 reporters have topped estimates.

**3M (MMM)** was a standout performer, jumping more than 5.4% to 7% after the industrial giant topped analysts' expectations for both profit and revenue in the latest quarter. The company also raised its full-year profit forecast, signaling confidence in its outlook.

**General Motors (GM)** also posted stronger-than-expected results, with adjusted earnings of $3.57 per share on revenue of $48.03 billion, driven by strong demand for trucks and SUVs. The automaker beat Wall Street's estimates and raised its full-year outlook, sending its stock up 2% in premarket trading.

Other notable movers included:

*   **Nebius (NBIS):** Rose 6.5% after Nvidia disclosed a 9.3% passive stake in the AI cloud firm.

*   **Equifax (EFX):** Dropped 12.4% after the credit ratings firm forecast annual profit below estimates.

### The Geopolitical Wildcard: Iran, Oil, and Tariffs

Despite the upbeat market sentiment, geopolitical tensions remained firmly in focus. Investors were weighing mixed signals from the U.S.-Iran conflict after a senior Iranian official told Reuters that Tehran had received a proposal from mediators for a 10-day ceasefire.

However, the situation remained fluid. U.S. Central Command carried out its 10th consecutive night of strikes on Iran after President Donald Trump declared the ceasefire "over". In response, Tehran reportedly targeted U.S. military assets across West Asia.

Adding to the uncertainty, Yemen's Iran-aligned Houthis said they would impose a naval blockade on Saudi Arabia, opening a potential new front against the United States and raising the threat to global energy supplies and trade beyond the Gulf.

**Oil prices remained elevated.** Brent crude futures returned to around $90 a barrel after earlier losses, reflecting the ongoing geopolitical risk premium. West Texas Intermediate crude futures climbed to around $84.60 per barrel.

Meanwhile, trade policy added another layer of complexity. On Monday, President Trump unveiled 50% tariffs on a wide range of imports from Canada, including beer, hockey sticks, milk, and chemicals, in response to Canada's treatment of American-made cars, alcohol, and dairy goods. The White House exempted Canadian oil imports from the tariffs, which come as crude prices trade near their highest levels since mid-June. The Financial Times also reported that Trump is expected to impose fresh tariffs on dozens of countries as soon as this week, with his 10% global tariff poised to expire on Friday.

### The Big Tech Earnings Specter

The main event for investors this week is the slate of megacap earnings, which could determine whether the AI trade has further room to run.

**Alphabet (GOOG, GOOGL)** reports on Wednesday, and investors will closely scrutinize its AI spending plans and cloud computing demand. The Street expects Alphabet to post adjusted earnings per share of $2.88, up 24.7% from a year ago.

**Tesla (TSLA)** also reports on Wednesday, providing a window into the health of the EV market and the company's margins.

**Intel (INTC)** and **IBM** are also scheduled to report this week, offering crucial signals on the semiconductor sector's momentum and the broader tech landscape.

Investors are expecting S&P 500 earnings growth of **26%** for the second quarter, year-over-year, up from an earlier estimate of 23.7%. That's a high bar—and one that leaves little room for disappointment.

### The Fed Factor: A Hawkish Shadow

While earnings and AI have been the primary drivers of the market, the Federal Reserve remains a key consideration. Traders now see a roughly 14% chance of a quarter-point rate increase at the Fed's July meeting and a 55% chance of a similar move in September, according to CME's FedWatch tool.

"Higher interest rates could be a real Achilles' heel for the market," said Chris Zaccarelli, chief investment officer for Northlight Asset Management. "If that were to happen, you have to question valuations, and that could impact the durability of this rally".

### Conclusion: A Market at an Inflection Point

July 21, 2026, was a day of recovery and anticipation. Chip stocks bounced back from a bear-market scare, adding billions in market value as investors looked past last week's fears and refocused on the structural AI demand story. Strong earnings from 3M and GM reinforced the narrative that corporate America is delivering. And the market turned its attention to the week ahead: the most closely watched slate of megacap earnings this quarter.

The stakes couldn't be higher. Alphabet and Tesla will test whether AI spending is translating into revenue growth. Intel will signal whether the semiconductor sector can regain momentum. And with markets expecting 26% S&P 500 earnings growth, there's little room for disappointment.

But the headwinds remain. Geopolitical tensions in the Middle East keep oil prices elevated. The Trump administration's tariff policies add another layer of uncertainty. And the Federal Reserve's hawkish stance looms over the market like a shadow.

As Chris Zaccarelli of Northlight Asset Management put it: "It's just a little bit harder to tell if they will be better than expected because there's such a high bar at this point".

The chip rebound was a promising start to the week. But the real test begins Wednesday, when the earnings season's main event gets underway.
