Weekly Market Analysis, April 26, 2026
## This Week's Key Theme: Semiconductor Rally Created by Intel's 'AI CPU Boom'
This week (ended April 20-24), the keyword for the U.S. stock market was an explosion in demand for AI server CPUs.
- Intel's Q1 earnings significantly exceeded market expectations, sending a message that demand for data center and AI CPUs has surged dramatically. Intel announced that data center and AI revenues increased more than 20% year-over-year, and accordingly, its stock price recorded the largest single-day gain since 1987.(ts2.tech)
- This news spread to competitors and allies alike in semiconductor and AI infrastructure stocks such as AMD, ARM, and ON Semiconductor. In particular, Intel emphasized that "AI workloads are shifting from GPU-centric 'training' to inference with higher CPU content," bringing renewed focus to the importance of server CPUs.(reddit.com)
So what does this mean?
It signals that in the AI era, it's not just about "buying graphics chips (GPUs)," but rather entering a phase where system-wide investments including CPUs, memory, and networks accompany overall spending. From an investor perspective:
- Opportunities can expand not just in individual AI star stocks, but across the entire semiconductor value chain (design, equipment, materials),
- At the same time, volatility risk for stocks whose valuations have already increased significantly could be seen as growing.
Looking at this week's 10-day (10D) performance, 9 out of 11 sectors recorded gains, indicating generally positive investor sentiment. However, Utilities (-2.25%) and Healthcare (-0.14%) showed slight or meaningful weakness despite their defensive nature.
Additionally, looking at 30D/120D trends:
- Technology: 10D +11.61%, 30D +14.51%, 120D +13.96%, with this week's rally accelerating the strong trend already underway over the past 1-3 months.
- Energy: 120D +36.38% shows long-term strength, but 10D is only +1%, and on a sector portfolio basis, it's in a mild rebound phase after a significant correction (-12.37%) since March 27, followed by recent recovery (from April 17 onward).
- Communication Services and Healthcare are relatively underperforming on a 120D basis, with this week's rebound being limited or even continuing the downtrend.
In summary, this week is less a shift to a new phase and more a continuation of the existing 1-3 month trend of "AI and semiconductor-led strength."

## Sector Performance: Technology Leads, Defensive Stocks Take a Break
### 1. Technology: AI Servers and Semiconductors Drive a Second Week of Acceleration
- 10D Return: +11.61% (Ranked #1 among 11 sectors)
- 30D: +14.51%, 120D: +13.96% — The sector leading the market over the medium to long term
- Representative Strong Performers: ARM (+57.8%), ON (+43.3%), AMD (+42.2%)
The primary driver of technology sector strength this week is semiconductors, particularly AI server chips.
- Following Intel's earnings surprise, CPU and AI-related stocks including Intel, AMD, and ARM surged in tandem. Intel, on the back of strong AI server CPU demand, even raised its revenue guidance, stating that "the CPU-to-GPU ratio in data centers could rise to 1:1 levels with AI 'agent' utilization."(reddit.com)
- ARM hit an all-time high (around $210 as of April 23) on a six-day winning streak and has risen roughly 80% or more year-to-date. In its Q3 earnings, ARM's revenue increased 26% year-over-year, with license and royalty revenues growing together, strengthening its position as "the foundation of the AI CPU era."(moneycheck.com)
- AMD is being re-evaluated as a "beneficiary of surging AI server CPU demand" thanks to Intel's earnings, with analysis suggesting its market cap is approaching $500 billion.(ts2.tech)
Looking at sector trends (piecewise):
- The technology sector has been on a +19.19% rally from March 27 through April 24, so this week's strength is an extension of an upward trend running for about a month.
What this means for investors:
In the short term, overheating debates about technology and semiconductors (valuation burden) could intensify. However, given that AI infrastructure investment is a structural, multi-year phenomenon rather than a one-off event,
- The ability to distinguish specific subsectors (foundry, design IP, equipment, testing, etc.) and
- Stocks that can defend valuations through earnings and cash generation
becomes critical during this period.

### 2. Financial Services: Quiet Beneficiary of Interest Rate and Capital Market Recovery
- 10D: +3.50%, 30D: +8.06%, 120D: +3.41%
- Weekly Top Performers: HOOD (+22.7%), APO (+19.2%), COIN (+19.0%)
This week, the financial services sector reflected both expectations of peak interest rates passing and capital market recovery.
- U.S. 10-year Treasury yields have fluctuated in the 4.3% range since April, but markets have already formed the perception that "additional spikes are limited." This creates a favorable environment for financial stocks broadly, including banks, asset managers, and private equity (PE) firms.(sentinelwealthgroup.com)
- Trading and cryptocurrency-related platforms such as COIN and HOOD showed strength, bolstered by improved risk-on sentiment and recovery in trading volumes.
Looking at sector trends (portfolio basis):
- Financial services bounced roughly +9.8% from March 30 through April 21, then entered a mild adjustment phase (-1.8%) after April 21. In other words, it's taking a breather after a short-term rally.
What this means for investors:
If interest rate peak-out signals continue, traditional financial stocks such as banks, brokerage firms, private equity, and insurance may continue their gentle recovery.
However, given that they have already risen more than 8% over the past month, earnings, dividend, and share buyback policies may determine individual stock prices in the short term.

### 3. Communication Services: Short-term rebound followed by pullback amid long-term underperformance
- 10D: +2.75%, 30D: +1.78%, 120D: -2.03%
- Top performers: TTD(+19.3%), MTCH(+15.9%), APP(+14.2%)
While some digital advertising, entertainment, and social platform companies rebounded on earnings expectations, the overall sector remains in a state of medium- to long-term underperformance (120D -2.03%).
Sector trend (portfolio basis):
- After an adjustment in early January-February, there was a rebound through March 5th, followed by an additional decline in the -8% range through late March, a +8.48% rebound from late March through April 22nd, and a -2.7% pullback from April 22nd onward.
- In other words, it's close to fluctuations within a wide range, with profit-taking appearing in the latter half of this week.
Implications for investors:
Given the sector's sensitivity to economic and advertising cycles, future consumption and advertising spending indicators and big tech advertising revenue guidance will likely determine sector direction. For now, it's a period when investor interest is relatively less compared to technology and semiconductors.

### 4. Real Estate: 'Gradual recovery' amid rate peak expectations vs. short-term adjustment
- 10D: +2.41%, 30D: +4.24%, 120D: +6.84%
- Top performers: ARE(+11.2%), BXP(+8.9%), EQIX(+7.6%)
The real estate sector is maintaining a plus performance (+6.84%) on a 120D basis, bolstered by expectations for long-term interest rate stability.
Looking at sector portfolio trends:
- Late January to mid-February: Gradual increase (+4.3%)
- February to late March: -7.9% adjustment
- March 27 to April 20: +11.4% strong rebound
- After April 20: -2.0% adjustment
In other words, a strong rebound has already occurred since late March, and this week can be viewed as a partial pullback from that rebound.
Implications for investors:
As long as interest rate peak-out expectations continue, a medium- to long-term recovery story may remain valid for quality REITs (data centers, logistics centers, prime office spaces). However, highly leveraged stocks remain sensitive to interest rate and liquidity risks.

### 5. Energy: Technical rebound level during adjustment period after long-term strength
- 10D: +1.06%, 30D: +1.86%, 120D: +36.38% (Ranked #1 among 11 sectors on 120D basis)
- Top performers: BKR(+9.7%), SLB(+8.1%), HAL(+7.4%)
With ongoing Middle East geopolitical risks, tensions related to the Strait of Hormuz, and concerns about reduced crude oil supply, the energy sector has shown clear strength this year.(media.licdn.com)
Sector portfolio trends:
- After rising more than +20% from late January through late March, it underwent an adjustment in the -12% range between March 27 and April 17.
- With a +4.9% rebound appearing in the week after April 17, this week's 10D performance (+1.06%) can be viewed as a continuation of the technical rebound following the adjustment.
Implications for investors:
Given that it has already risen more than +36% on a 120D basis, it is exposed to volatility from oil prices and geopolitical news in the short term. Energy stocks typically have relative defensive characteristics during periods of economic slowdown, but at this stage when prices have already risen significantly, timing management for buying and selling is crucial.

### 6. Consumer Sector: 'Ambiguous' period for both defensive and cyclical consumption
#### Consumer Defensive
- 10D: +0.43%, 30D: -1.68%, 120D: +5.67%
- Top performers: KDP(+10.0%), EL(+7.1%), TGT(+5.9%)
- Sector portfolio basis: The overall return is slightly negative at -1.97%, and while there has been a rebound (+2.0%) since March 20, it has yet to recover to previous highs.
Defensive consumer stocks are positive on a long-term basis due to steady demand despite inflation and interest rate pressures, but the recent one-month (30D) performance is relatively weak at -1.68%.
#### Consumer Cyclical
- 10D: +1.45%, 30D: +2.85%, 120D: +2.63%
- Top performers: CVNA(+21.6%), DASH(+15.9%), DHI(+12.1%)
- Sector portfolio basis: -3.6% adjustment after April 20, with a +10.8% rebound from late March to April 20 prior.
Implications for investors:
- Defensive consumer stocks have a strong perception of being "expensive but safe," and stocks without a growth story (e.g., premium brands, structural market share expansion) may lack clear direction.
- Consumer cyclical stocks can still move sensitively based on interest rates, employment, and wages, so an approach that considers individual industry cycles such as housing, automobiles, and travel may be more advantageous than short-term trading.

### 7. Healthcare and Utilities: The paradox of traditional 'defensive stocks'
- Healthcare 10D: -0.14%, 30D: +0.37%, 120D: +0.59% (essentially flat)
- Utilities 10D: -2.25%, 30D: -0.36%, 120D: +5.95%
Healthcare has remained in a consolidation range with alternating ups and downs since Q1. Looking at the sector portfolio:
- Late February to mid-March: Sharp decline of -7.8%
- Late March to April 17: +5.45% rebound
- After April 17: -2.26% re-adjustment
Utilities, after a strong rally in January-February (+9.4%), have seen increased volatility since March and have been in a -2.97% downtrend from April 9 to present.
Implications for investors:
Traditionally, healthcare and utilities have played a defensive role during economic slowdowns and crisis periods. However, now:
- With capital flowing to growth stories like artificial intelligence, semiconductors, and big tech,
- 'Growth' is being prioritized over 'safety.'
From a portfolio perspective, it's also time to check whether the weighting of these defensive sectors has been set too low. Considering dividends and defensive characteristics while prices have been sluggish, it could be an opportunity to gradually increase weightings from a medium- to long-term diversification investment perspective.

## Key Stock Trends: ARM·AMD·ON — AI Infrastructure Trio
### 1. Arm Holdings (ARM): ‘AI CPU Era Design Standard’ Premium
- This week's 10-day return: +57.8%
- With six consecutive trading days of gains, the stock price hit an all-time high (in the $210 range) on April 23rd. (moneycheck.com)
- ARM has a business model of licensing CPU designs (IP) used in various devices such as smartphones, servers, and automobiles.
- Recent results showed a 26% increase in revenue year-on-year, with demand for AI and data center CPUs exploding, leading to growth in royalties and license revenue. (moneycheck.com)
Investment Points:
ARM doesn't manufacture chips directly, but it occupies a position similar to the 'standard language' of chip design worldwide. As the scope of AI servers, edge computing, and automotive electronics expands, the leverage effect (earnings sensitivity) of companies holding design standards could increase.
---
### 2. AMD: Intel Tailwinds 'Paradoxically' Raised Expectations
- This week's 10-day return: +42.2%
- After Intel's earnings announcement, the market interpreted it not as a simple competitive landscape but as a signal that "the overall pie (market size) of CPUs is growing."
- AMD was already expected to grow in AI GPUs (e.g., MI300 series) and data center CPUs (EPYC), so Intel's earnings acted as verification that "structural demand for AI server CPUs is right." (coincentral.com)
Investment Points:
- Short-term price increases may lead to adjustment risks.
- However, in the long term, if AI infrastructure investment continues, AMD remains a key player as a company with growth engines on both CPU and GPU sides.
---
### 3. ON Semiconductor (ON): 'Quiet Winner' in Power and Sensors
- This week's 10-day return: +43.3%
- While there is relatively less specific weekly news compared to mega-caps, the company is exposed to structural growth areas such as electric vehicles, industrial power semiconductors, and image sensors. It sits at the intersection of three long-term themes: AI, electric vehicles, and industrial automation.
Investment Points:
AI data centers consume enormous amounts of power, and electric vehicles and industrial robots require sophisticated power control. In this environment, power semiconductor and sensor companies are likely to see robust long-term demand as 'essential components' rather than 'platforms'.

## Next Week's Key Points: From 'AI Expectations' to 'Earnings Verification'
1. Big Tech and Semiconductor Earnings Season Begins in Earnest
- Intel's signal this week was very strong, but the market's focus is now shifting to whether other big tech and semiconductor companies can back up these expectations with actual earnings.
- AMD's earnings, along with guidance on AI infrastructure investment from major cloud providers (hyperscalers), will determine whether the current technology and semiconductor rally continues or takes a breather.
2. Bond Market and Interest Rate Reactions
- If inflation and employment figures come in stronger than expected, concerns about "delayed/reduced Fed rate cuts" could resurface. This could put pressure on growth stock valuations and accelerate sector rotation back into financials, energy, and defensive stocks.
3. Continued Geopolitical and Energy Risks
- If geopolitical risks in the Middle East and other regions have a tangible impact on crude oil supply, the already-rising energy sector could see further rallies and volatility.
4. Sectoral 'Overheating vs Opportunity' Check
- Technology and Semiconductors: Short-term overheating signals (RSI, valuation, etc.) are increasing, so a strategy of considering entry/additional purchases after earnings and guidance confirmation may be more rational.
- Healthcare, Utilities, Real Estate: This could be a good time to consider a long-term diversification strategy of gradually buying high-quality stocks with dividend payouts and defensive capabilities in these relatively neglected defensive sectors.
In summary, this week was driven by the AI CPU boom sparked by Intel's announcement. Next week will likely be a 'time of verification' to see how much of this expectation is actually reflected in earnings.
