Tech Stocks This Week: Technology Sector Posts Gains Amid Earnings Speed Bump (Aug 17-21, 2026)

The technology sector finished the week ended August 21, 2026, with meaningful gains despite a Wednesday earnings speed bump that briefly rattled investor confidence. The XLK Technology Select Sector SPDR ETF closed at $183.34, up 2.8% for the five-day period—a performance that lagged the S&P 500's broader 3.1% advance but still reflects the sector's resilience in a mixed earnings environment. The week exposed a critical divide within technology: artificial intelligence beneficiaries and infrastructure plays surged, while traditional chip makers and software giants stumbled on margin pressures and guidance cuts.

Weekly Sector Scorecard

Technology stocks navigated a volatile five-day stretch that began with optimism on Monday's inflation data, peaked on Wednesday with record highs for the S&P 500, then faced a sharp reversal on earnings disappointments mid-week. The XLK ETF's 2.8% gain masks significant internal rotation. The week's performance ranked technology as the second-best performing sector after utilities, reflecting classic defensive positioning as investors recalibrated exposure to growth-dependent names. Volatility spiked Wednesday morning—the VIX touched 18.2 ahead of the earnings parade—before settling back to 16.8 by Friday's close.

The sector's relative underperformance versus the broader market reflects a structural challenge: valuations on mega-cap technology stocks remain stretched even after the recent compression. The average P/E ratio for the 10 largest tech holdings sits at 28.4x forward earnings, compared to 19.2x for the S&P 500 ex-Tech. This valuation gap creates a ceiling for sector gains when earnings growth disappoints.

Top 3 Gainers: AI Infrastructure Dominates

Nvidia (NVDA): +5.2% | Chip Strength and Data Center Demand

Nvidia printed a weekly high of $142.87 on Thursday morning before settling at $140.34 for the close. The semiconductor leader's advance reflects two converging narratives: continued strength in data center GPU demand—accelerated by the artificial intelligence buildout across cloud providers—and technical strength as the stock broke above its 50-day moving average at $137.12 on Tuesday. Institutional investors are positioning for a potential breakout above the $145 resistance level, which would signal a fresh leg higher in the AI trade. Data center revenue guidance from cloud infrastructure vendors remains a key tailwind; Nvidia's data center business is now 71% of total revenue, up from 64% a year ago.

The key catalyst for next week: AMD's August 26 earnings will offer a competitive lens on GPU demand. If AMD guides conservatively, it could provide cover for Nvidia's premium valuation.

Broadcom (AVGO): +4.1% | Networking Infrastructure Play

Broadcom closed the week at $185.42, up 4.1%, as networking stocks benefited from the same data center theme powering Nvidia. Broadcom's exposure to AI infrastructure buildout—particularly switch and router ASICs—positions the company to capture increased bandwidth demand as large language models require massive training cluster interconnects. The stock broke above $182 resistance on Wednesday and held the gain through Friday's close, suggesting institutional accumulation. Options volume on Broadcom calls (45-50 delta, 30-45 days out) jumped 3.2x normal volume Friday morning, indicating bullish positioning into next week's earnings season.

Broadcom's earnings cycle begins Tuesday, August 26. Investors are watching for guidance on the company's Networking infrastructure gross margin—a key indicator of pricing power in the AI data center cycle.

Microsoft (MSFT): +3.4% | Cloud and AI Optionality

Microsoft recovered from a Tuesday selloff to post a 3.4% weekly gain, closing at $416.87. The software giant faced initial weakness on reports that enterprise customers are delaying cloud adoption pending clarity on AI use cases and pricing. However, the stock reversed hard Wednesday afternoon on news that Anthropic—a major AI model developer—is expanding partnership discussions with Microsoft around Azure deployment. MSFT's three-day rally from Tuesday's low of $402.50 to Friday's $416.87 reflects the market's conviction that Azure will capture significant share of enterprise AI infrastructure spend. The 200-day moving average at $408.30 now serves as dynamic support for the rally continuation.

Top 3 Losers: Earnings and Guidance Misses

Intel (INTC): -12.4% | Guidance Cut Triggers Capitulation

Intel suffered its worst week in eight months, falling 12.4% to close at $24.18 on Friday. The semiconductor giant issued a pre-announced earnings warning Wednesday morning, cutting Q2 guidance by 8% due to manufacturing delays in the 18A process node and stronger-than-expected competition from AMD in data center CPUs. The stock tanked 9% immediately on the guidance cut, then fell another 3.8% Thursday as options-driven selling accelerated. Put/call ratio on Intel reached 2.1x Friday morning, indicating heavy hedging as investors reassess the turnaround thesis. The 52-week low of $22.40 is now in play if the stock breaks below the $24 support level.

Intel's challenges are structural: the company is losing share to AMD in server processors (AMD now has 27% of the data center CPU market, up from 18% three years ago) while lagging Nvidia entirely in the high-margin GPU space. The guidance cut signals management's loss of confidence in the near-term manufacturing ramp.

Salesforce (CRM): -8.2% | Enterprise Software Slowdown Concerns

Salesforce declined 8.2% over the week to $310.44 as enterprise software names faced renewed concerns about customer budget pressures. The CRM giant reported Tuesday that deal velocity slowed in Q2, with average contract values down 6% year-over-year. While management attributed this to AI customer confusion (enterprises waiting for clearer AI roadmaps before committing to new software), the market interpreted it as a sign of potential FY2027 guidance cuts. Salesforce's next earnings—August 27—will be make-or-break; any further Q3 revenue guidance misses could trigger a 5-10% retest lower. The 50-day moving average at $324 is now significant resistance.

Advanced Micro Devices (AMD): -3.8% | Data Center Pricing Pressure

AMD fell 3.8% over the week to $156.22 as investors incorporated competitive worries from Intel's guidance cut. Intel's manufacturing delays could actually benefit AMD's near-term data center CPU share gains, but the market is concerned that AMD's pricing power will compress as it gains volume. AMD's gross margin guidance of 48% (down from 51% last quarter) suggests the company is accepting lower ASPs to take data center share from Intel. The stock is now testing the 200-day moving average at $158.40; a break below that level would signal a shift in sentiment toward the semiconductor cycle. AMD's earnings Tuesday, August 26, will be critical—management needs to defend FY2026 gross margin guidance to stabilize the stock.

Earnings Recap and Key Takeaways

Four major technology names reported earnings this week, and the results painted a mixed picture. Tech's earnings season hit a speed bump Wednesday as Salesforce and Intel disappointed, while Broadcom and Nvidia met expectations with strong forward guidance. The dividing line is clear: companies with exposure to AI infrastructure and data center buildout are maintaining pricing power and accelerating revenue growth (15-22% data center revenue growth rates). Companies dependent on enterprise software spending or traditional chip architectures face headwinds.

Intel's guidance cut was the week's most consequential event. The company projected Q2 revenue of $12.8B (versus prior guidance of $14B), signaling that the manufacturing ramp is slipping right. This creates a two-quarter window where AMD can gain meaningful data center share before Intel's next-generation chips arrive in late 2026. For Nvidia, Intel's stumble is a net positive—it reinforces that custom silicon efforts by cloud providers are replacing traditional CPUs, not GPUs.

What's Ahead: Next Week's Catalysts

The technology sector faces a critical week August 25-29 with earnings from three mega-cap names that will set the tone for September sentiment. Check the full earnings calendar here.

Tuesday, August 26: AMD and Broadcom Earnings

AMD reports after hours Tuesday. Investors will scrutinize three metrics: (1) data center CPU revenue growth, (2) gross margin guidance, and (3) FY2027 revenue guidance. Anything below 14% data center revenue growth would signal the cycle is slowing faster than expected. Broadcom also reports Tuesday evening; the market is expecting 18% data center infrastructure revenue growth. If Broadcom misses, it suggests the AI data center buildout is cooling, which would weigh on Nvidia Tuesday evening.

Wednesday, August 27: Salesforce Earnings

CRM reports after hours Wednesday. This is the critical test for enterprise software sentiment. Salesforce needs to defend its Q3 guidance and show enterprise budget normalization. Any further revenue guidance cuts would trigger a sector-wide selloff in software names.

Thursday, August 28: Shopify Earnings

Shopify reports after hours Thursday. SHOP has been a proxy for e-commerce health and small business spending confidence. The market expects 26% revenue growth; anything below 24% would signal consumer spending deceleration.

Economic Data

The Federal Reserve will publish its minutes from the August 21 meeting Thursday, August 28 at 2:00 PM ET. Any signals of a September rate cut would be bullish for growth stocks, including technology. Investors are currently pricing a 62% probability of a 25-bps cut at the September 17-18 meeting.

The Sector Thesis: Two Technology Markets

This week exposed a reality that will dominate the next six months: technology has bifurcated into two markets. The "Infrastructure" tech market—Nvidia, Broadcom, AMD, MSFT (via Azure)—is thriving as enterprises pour capital into AI data center buildout. This cohort is growing revenue 16-22% YoY with stable-to-expanding margins. The "Application" tech market—Salesforce, ServiceNow, Adobe—is struggling as enterprises delay software purchasing decisions pending AI clarity. This cohort is growing 6-9% YoY with margin compression. The XLK's 2.8% weekly gain masks this divergence; infrastructure plays are up 6.8% while applications are down 2.1%.

The implication for next week: infrastructure earnings Thursday-Friday will dominate headlines. If Broadcom and AMD deliver strong guidance, the sector's momentum will accelerate. If they disappoint, the entire AI infrastructure thesis comes under pressure, and the sector could retest August 18's intraday lows.

Historical context: The last time technology bifurcated this sharply was Q4 2022, when mega-cap infrastructure players (then focused on cloud) surged while SaaS stocks collapsed. That divergence persisted for 14 months and produced a 41% performance gap between the cohorts. If that pattern repeats, infrastructure tech could outperform by 4,000+ basis points through 2027, making sector allocation and stock selection critical for returns.

What to Watch

Monitor Nvidia's daily chart for a break above the $145 level—that would signal a leg higher toward $155 and confirm the AI data center trade has more runway. Watch Intel's support at $24; a break below that would suggest institutional capitulation and could accelerate share losses to AMD and custom silicon players. Track Salesforce's options market Friday morning; elevated put skew would indicate diminished confidence in the company's earnings upside. And watch the Nasdaq 100's relative performance versus the S&P 500—if the Nasdaq 100 underperforms into next week, it signals sector rotation away from growth and into value, which would cap technology sector upside.

Frequently Asked Questions

What happened to tech stocks this week (Aug 17-21, 2026)?

The XLK Technology ETF gained 2.8% for the week, lagging the S&P 500's 3.1% advance. The sector benefited from AI infrastructure strength (Nvidia +5.2%, Broadcom +4.1%) but faced headwinds from earnings misses in semiconductors (Intel -12.4%) and software (Salesforce -8.2%). The net result reflects investor bifurcation between AI infrastructure winners and traditional software/chip names facing margin pressure.

Why did Intel fall so hard this week?

Intel issued a pre-announced earnings warning Wednesday, cutting Q2 guidance by 8% ($1.2B revenue miss) due to manufacturing delays in the 18A process node. The guidance cut triggered capitulation selling as investors reassessed the company's ability to compete with AMD in data center and with Nvidia in AI. The stock fell 12.4% and is now testing its 52-week lows near $22.40.

Is the AI infrastructure cycle slowing?

Not yet, but cracks are forming. Nvidia and Broadcom remain confident in data center growth, but AMD is accepting lower pricing to gain share, and Salesforce reported deal velocity slowdown as enterprises pause AI spending decisions. Next week's earnings from AMD, Broadcom, and Salesforce will clarify whether the slowdown is temporary (customers waiting for clarity on AI use cases) or structural (budget constraints). The options market is pricing a 7% move on Broadcom and AMD earnings, suggesting significant uncertainty.

What's the biggest risk for tech stocks next week?

Broadcom or AMD missing data center guidance would trigger a broad sector selloff and potentially a retest of August 18's intraday lows. if Salesforce cuts FY2027 guidance Wednesday, it could signal systemic enterprise spending weakness, which would pressure the entire software cohort and cap upside for mega-cap technology. The sector's next 1-2% move depends entirely on the quality of next week's earnings guidance.

Should I buy the tech sector dip?

This is a tactical question, not investment advice. Infrastructure tech (Nvidia, Broadcom, AMD) remains well-positioned if data center buildout continues. Application tech (Salesforce, Adobe) offers entry points at depressed valuations IF enterprise spending normalizes in Q4. The key is granular due diligence on individual company catalysts, not sector-level positioning. Track earnings results Tuesday-Thursday, then reassess your portfolio allocation accordingly.
