Stock Market Today: Dow, S&P 500, Nasdaq Climb as Chip Stocks Rebound Ahead of Big Tech Earnings
## After last week's brutal selloff sent the semiconductor sector into a bear market, chip stocks roared back on Monday—just in time for the most anticipated earnings week of the quarter.
---
### Introduction: The Calm After the Storm
Just five trading days ago, the semiconductor sector was in freefall. The PHLX Semiconductor Index (SOX) had tumbled more than 20% from its late-June record high, officially entering a bear market. The Nasdaq Composite had given back 2.9% for the week, its worst performance in months. Investors were spooked by a Chinese AI breakthrough, mounting concerns about hyperscaler spending, and the violent unwind of leveraged positions in memory stocks.
Then came Monday.
The three major U.S. indexes climbed higher as chip stocks mounted a broad-based recovery, with memory names leading the charge. The Dow Jones Industrial Average rose 0.28%, the S&P 500 gained 0.66%, and the Nasdaq Composite advanced 0.99%. Futures had signaled the rebound earlier in the day, with Nasdaq-100 E-minis up 0.82% and S&P 500 E-minis gaining 0.37%.
The catalyst? A combination of bargain hunting after an oversold condition, a pullback in oil prices after Iran signaled it remained open to negotiations, and a market pivoting its focus to this week's slate of megacap earnings—the first real test of whether the AI trade can deliver on its promises.

### The Chip Rebound: Memory Stocks Lead the Charge
The semiconductor sector's recovery was broad-based, but memory chipmakers were the standout performers.
**Micron Technology** jumped more than 4% in premarket trading, with some sources reporting gains of up to 4.07%. The stock had been crushed nearly 14% the previous week after Chinese memory maker CXMT announced plans for an $8.5 billion IPO and reports surfaced about potential HBM export restrictions. Yet Micron's underlying fundamentals remain extraordinary: Q3 fiscal 2026 revenue of $41.46 billion, up 345.7% year-over-year, with gross margins of 84.9%. The company has already shipped more than $1 billion in HBM4 revenue and locked in 16 strategic customer agreements covering roughly **$100 billion** in remaining performance obligations.
**SK Hynix**, which recently made its Nasdaq debut, surged more than 5% in premarket trading. **SanDisk** gained over 3%, while **Western Digital** and **Seagate Technology** each rose between 2.5% and 4.7%.
Other chip heavyweights joined the rally. **AMD** jumped 4% after Rosenblatt selected it as a "top pick" and raised its price target to $665, while UBS also raised its target to $700. **Nvidia** rose more than 1%. **Broadcom** and **Intel** were poised to gain, while equipment makers like **ASML**, **Applied Materials**, and **Lam Research** edged higher.
The coordinated rally added more than **$30 billion** in pre-market value to the memory chip sector alone. As semiconductor analyst Rachel Kim put it: "The market is repricing memory names after overcorrecting on CXMT's IPO fears. The structural shortage thesis hasn't changed — if anything, Q3 guidance from Micron and SanDisk confirmed it".

### Why the Recovery Matters: A Sector at a Crossroads
The chip rebound comes at a critical juncture. Last week's selloff was driven by a confluence of fears:
1. **The Moonshot Effect**: Chinese startup Moonshot unveiled Kimi K3, a 2.8 trillion-parameter open-weight model that runs at a much lower cost than U.S. models. This raised existential questions about whether the industry's current capex trajectory is sustainable if similar performance can be delivered more cheaply.
2. **The Leveraged ETF Unwind**: South Korean retail investors had piled into leveraged ETFs tracking SK Hynix and Samsung, which grew to about $9.1 billion within a month. The largest had fallen more than 40% since its debut, triggering margin calls and forced selling.
3. **Valuation Concerns**: The SOX had more than doubled in just three months. Even after the pullback, it remained up about 65% year-to-date.
But the fundamental AI demand story remains intact. Micron CEO Sanjay Mehrotra has warned that the structural memory shortage will persist "beyond calendar 2027". JPMorgan strategists led by Mislav Matejka argued that the semiconductor selloff was overdone, noting that "meaningful" chip supply additions are not likely before 2028. They see support coming from strong earnings and evidence that these stocks are worth their share prices.

### The Divide on Wall Street: JPMorgan vs. Morgan Stanley
Not everyone agrees on what comes next. Two of Wall Street's biggest banks offered diverging views on Monday.
**JPMorgan** sees a summer buying opportunity. The strategists believe semiconductors "should soon start to find a bid," driven by strong earnings and the unwinding of the momentum factor that had driven investors to pile into those stocks. If hyperscaler capital expenditure guidance remains strong, "we think investors should step back into the space over summer".
**Morgan Stanley** takes a more cautious view. While acknowledging that a bounce is likely after a 20% correction, Mike Wilson's team doesn't think chips will "regain their leadership position in the second half of this year". Instead, they believe the broadening rally has legs, with consumer discretionary goods and transports poised to lead the market higher. Morgan Stanley prefers hyperscalers over semiconductors for the next several months, though the former has already gained a 30% edge over chips in three weeks, making the risk/reward "less attractive".

### The Earnings Week Ahead: All Eyes on Big Tech
If chip stocks are the appetizer, this week's megacap earnings are the main course. The second-quarter earnings season will pick up pace with reports due from several of the market's most influential companies.
**Alphabet and Tesla** report after the close on Wednesday, July 22. With valuations for mega-cap tech looking stretched, any missteps in forward guidance could spark rapid sector rotations. Investors will closely watch Alphabet's outlook for AI spending and cloud growth. The Street expects Alphabet to post adjusted EPS of $2.88, up 24.7% from a year ago.
**Intel** also reports this week, providing a crucial signal on whether the semiconductor sector can regain momentum. **IBM** rounds out the slate of major reports.
Markets 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 Geopolitical Wildcard: Oil and Iran
The chip rally wasn't the only story on Monday. Oil prices briefly topped **$90 a barrel** for the first time since early June, reaching their highest level in over a month. The surge came as the U.S. entered its ninth consecutive day of strikes against Iran.
But oil pulled back after Iranian Foreign Ministry spokesman Esmail Baghaei stated publicly that back-channel communications had persisted and that the two sides could still pursue a negotiated outcome. Brent crude retreated to around $88.25, and U.S. crude futures traded near $82.25.
The market broadly doubts Washington has the appetite for a significant military build-up in the region, and without such a step, a negotiated end to the conflict looks unavoidable.

### The Fed Factor: Quiet Before the Storm
This week offers little in the way of economic catalysts, as Fed officials have entered a communications blackout before their rate decision the following Wednesday.
Markets are pricing in about a **12% chance** of a quarter-point rate hike at the July meeting and a roughly **53% chance** of another hike in September. The Cboe Volatility Index (VIX) slipped to 18.22, a decline of roughly 2.93% on the session, pointing to diminishing short-term fear in the market.

### Conclusion: A Market at an Inflection Point
July 20, 2026, was a day of recovery—but also a day of anticipation. Chip stocks bounced back from a bear-market scare, adding more than $30 billion in market value as investors looked past last week's fears and refocused on the structural AI demand story. Oil prices eased after Iran signaled openness to negotiations. 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.
As Jack Herr, senior investment analyst at GuideStone Funds, put it: "There's just a little less room for error in the market at this point. Any sort of events or earnings news could probably move the market down".
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.
