The Nasdaq Composite Index broke its all-time high at 16,800 points, extending the tech stock rally. Major tech companies delivered earnings that beat market expectations in Q3, with AI-related revenue growth particularly standout. TQQQ (ProShares UltraPro QQQ), which tracks the Nasdaq 100 at 3x leverage, gained +12% for the month, drawing the attention of aggressive investors. The semiconductor sector ETF SOXX rose +8%, with NVIDIA and AMD posting strong gains on surging AI infrastructure demand. Tech investors should use the asset allocation calculator to ensure their technology weighting hasn't grown excessive, and use the rebalancing calculator to manage valuation risk.
Big Tech Q3 Earnings and Market Impact
Big tech companies delivered Q3 earnings that far exceeded market expectations. Microsoft posted revenue of $56.5 billion (+13% year-over-year) and net income of $22.1 billion (+27%), with Azure cloud revenue surging +29% as AI service demand exploded. Copilot AI service subscriptions surpassed 1 million, accelerating the AI transition in productivity software. Apple achieved revenue of $89.5 billion (+6%) and net income of $22.9 billion (+11%), with iPhone 15 series sales surpassing expectations, China market recovery exceeding forecasts, and services revenue growing +16%—expanding the share of high-margin business to improve overall profitability. Google reported revenue of $76.3 billion (+11%) and net income of $19.6 billion (+42%): search ad revenue grew +12%, holding firm despite economic slowdown concerns, YouTube ad revenue increased +12%, and cloud revenue surged +22%, reflecting benefits from AI infrastructure investment. Amazon posted revenue of $143.1 billion (+13%) and net income of $9.9 billion (+344%), with AWS cloud revenue growing +12% on rising AI training infrastructure demand, and advertising revenue exploding +26% as the value of Amazon's advertising platform is being re-rated. Meta reported revenue of $34.1 billion (+23%) and net income of $11.7 billion (+164%), with ad revenue surging +24% on improved AI-driven targeting efficiency, and Reels ad monetization fully ramping up—proving the profitability of short-form content.
A common thread across big tech earnings was a surge in AI revenue: cloud AI services (Azure, AWS, GCP) grew +25–30% year-over-year, generative AI services such as Copilot and Gemini are spreading among enterprise customers, and demand for AI chips (NVIDIA H100/H200) has exploded, keeping semiconductor supply tight. Profitability also improved: operating margins rose to Meta 40% (from 36%), Google 28% (from 24%), and Microsoft 48% (from 46%), as AI investment efficiency and cost reduction proceeded simultaneously to improve margins, with the growing share of high-margin businesses (cloud, advertising) lifting overall profitability. On valuation, the average P/E for big tech is 30x—a 43% premium over the S&P 500 (21x)—but the PEG ratio (P/E divided by growth rate) remains at a reasonable 1.5 given AI growth expectations. Historically, P/E was 60x during the 2000 dot-com bubble and 40x during the 2021 pandemic bubble, making the current level relatively stable by comparison.
Use the rebalancing calculator to sell a portion of your position if big tech-heavy ETFs (QQQ, TQQQ) exceed your target weighting to lock in gains, and use the asset allocation calculator to simulate valuation risk and expected returns under tech weighting scenarios of 50%, 60%, and 70% to maintain a technology allocation suited to your personal risk tolerance.
TQQQ Leveraged ETF Investment Strategy and Risks
TQQQ is an ultra-aggressive ETF that tracks the Nasdaq 100 at 3x daily leverage. How TQQQ works: if the Nasdaq 100 rises +2%, TQQQ gains +6%; if it falls -2%, TQQQ drops -6%, amplifying volatility by a factor of three. The fund resets its leverage ratio to 3x every day at midnight, so holding it long-term can cause its returns to diverge from a simple Nasdaq 100 × 3 due to compounding effects. It uses derivatives (futures, swaps) to achieve leverage, resulting in a higher expense ratio of 0.95% and additional financing costs.
Recent performance: the Nasdaq 100 is up +28% year-to-date in 2025, while TQQQ has surged +95%—exceeding 3x returns due to the compounding effect. Monthly volatility is 45% for TQQQ versus 15% for the Nasdaq 100, and daily maximum swings are ±9% for TQQQ versus ±3% for the Nasdaq 100, placing enormous psychological pressure on investors. In the 2022 bear market, the Nasdaq 100 fell -33% while TQQQ dropped -79%, wiping out 80% of principal; recovery took 18 months for the Nasdaq 100 but 24 months for TQQQ—leveraged ETFs take longer to recover.
TQQQ suitability: it is appropriate for short-term traders (1 day to 1 week) who have a strong directional view on the Nasdaq, for high-risk-tolerant investors who can withstand principal losses of -50% or more, and for allocations of 5% or less of total portfolio value. It is not appropriate for long-term investors (1 year or more), as compounding drag and high costs cause long-term returns to fall short of Nasdaq 100 × 3; for retirement savings investors aged 50–60 who need principal preservation (avoid entirely); or for investors who do not understand daily rebalancing and compounding effects and may suffer unexpected losses.
Alternatives to TQQQ: QQQ (1x Nasdaq 100 ETF) has a low expense ratio of 0.20%, volatility one-third that of TQQQ, is suitable for long-term investing with no compounding drag, and is recommended for conservative tech investors with a possible allocation of 30–40% of portfolio. The TQQQ Cash-Secured strategy involves investing only 30% of your intended TQQQ exposure and holding the remaining 70% in cash or short-term Treasuries (SHY), capping the total portfolio loss at -24% (30% × -80%) even in a TQQQ -80% crash. Add to the position with cash on sharp declines to lower the average cost basis—capturing the leverage benefit while avoiding insolvency risk. The QQQ + TQQQ combination strategy—80% QQQ and 20% TQQQ—moderates the leverage effect while seeking additional return; total portfolio volatility increases roughly +30% versus QQQ alone but decreases roughly -60% versus TQQQ alone. This is suitable for balanced-aggressive investors who rebalance quarterly to maintain the weighting.
Practical TQQQ principles: apply strict stop-loss rules—sell unconditionally if TQQQ falls -20% after purchase to limit further declines (when the Nasdaq 100 drops -7%, TQQQ falls -21%, so early warning is needed). Follow profit-taking rules: sell 50% on a +30% gain to lock in profits, sell another 30% on a +50% gain to recover principal, and hold the remaining 20% long-term to capture further upside. Limit TQQQ to 5% or less of total assets, allocating the other 95% to stable assets such as QQQ, SPY, and AGG; if TQQQ exceeds 10%, sell immediately to manage risk.
Use the rebalancing calculator to set a target TQQQ weighting (e.g., 5%) and sell the excess if a Nasdaq surge pushes it above 8%. Use the asset allocation calculator to simulate your total portfolio loss under a Nasdaq -30% crash across TQQQ scenarios of 0%, 5%, and 10% to determine a TQQQ allocation suited to your personal risk tolerance and manage leverage risk rigorously.
Semiconductor Sector Outlook and SOXX ETF Analysis
The semiconductor industry has entered a super cycle driven by explosive AI demand. SOXX (iShares Semiconductor ETF) invests in 30 U.S. semiconductor companies; its top holdings are NVIDIA 20.5%, Broadcom 5.8%, Intel 5.2%, AMD 4.9%, and Texas Instruments 4.5%. The expense ratio is 0.35%, and SOXX has gained +42% year-to-date in 2025, far outpacing the Nasdaq 100 (+28%). The dividend yield is a low 0.8%, but as a growth-oriented holding, price appreciation is the primary return driver.
Growth drivers for the semiconductor sector: AI chip demand is exploding—NVIDIA H100/H200 GPUs cost $30,000–$40,000 each and supply shortages are expected to persist through 2026, while Microsoft, Google, and Amazon each invest over $10 billion annually in AI infrastructure, fueling explosive GPU demand. AMD's MI300 GPU is also gaining market share, emerging as an alternative to NVIDIA. In automotive semiconductors, the spread of EVs and autonomous driving is raising semiconductor content per vehicle to $1,000 (versus $500 in traditional vehicles); Tesla, BYD, and others are deploying AI chips in autonomous driving systems, increasing demand for high-performance chips, and NVIDIA leads the automotive AI chip market (Drive Orin). On 5G and data centers, the expansion of 5G base stations is boosting demand for communications chips; data center expansion is driving solid demand for server semiconductors (Intel Xeon, AMD EPYC); and Broadcom's networking chips are benefiting from cloud infrastructure expansion. On supply chain diversification, U.S.-China tensions are spurring growth in domestic U.S. chip fabrication to reduce China dependence, with Intel and TSMC building major fabs in Arizona, Arizona and $50 billion in government subsidies from the CHIPS Act.
Semiconductor sector risks: valuation pressure is a concern—SOXX at 35x P/E carries a 67% premium over the S&P 500 (21x), NVIDIA at 65x P/E is near historical highs and faces significant correction risk if AI expectations become excessive, and the semiconductor cycle has pronounced boom-bust swings with a correction possible at the current boom peak. On economic sensitivity, semiconductors are a leading economic indicator: IT spending is the first to decline in a slowdown; semiconductor stocks crashed -40% during the 2022 PC and smartphone demand slump; and if AI demand decelerates, NVIDIA and AMD share prices could plunge sharply. On competitive intensity, AMD is eating into NVIDIA's market share and intensifying pricing competition; Intel is re-entering the foundry business to compete with TSMC; and Chinese chipmakers (SMIC) continue to grow despite U.S. technology restrictions.
SOXX investment strategy: allocate 10–15% of the portfolio for semiconductor sector exposure to capture growth opportunities while recognizing elevated valuation risk. Since the Nasdaq 100 (QQQ) already includes NVIDIA and Broadcom, avoid double-counting and limit combined QQQ + SOXX exposure to 50% or less. Reassess valuation at each quarterly earnings announcement: take some profits if P/E rises above 40x, and consider adding if P/E falls below 25x. If recession signals appear (declining PMI, rising unemployment), cut SOXX exposure by 50% to protect against losses; exit immediately if AI demand decelerates (NVIDIA guidance lowered) to avoid further downside.
Alternative ETFs to SOXX: SMH (VanEck Semiconductor ETF) has the same 0.35% expense ratio, includes global semiconductor companies such as TSMC and ASML for superior global diversification, and shows a 0.95 correlation with SOXX—nearly identical performance. XSD (SPDR S&P Semiconductor ETF) uses equal weighting, giving NVIDIA a 3.3% weight (versus 20.5% in SOXX), diversifying away from large-cap concentration risk; exposure to small- and mid-cap semiconductor names raises volatility but also increases upside potential.
Use the rebalancing calculator to set a target SOXX weighting (e.g., 10%) and sell the excess if a semiconductor rally pushes it above 15% to lock in gains. Use the asset allocation calculator to simulate your total portfolio loss in a semiconductor cycle correction (-30%) across SOXX scenarios of 5%, 10%, and 15% to determine a semiconductor sector allocation suited to your personal risk tolerance and manage elevated valuation risk rigorously.
AI Infrastructure Investment and the Cloud Sector
The AI revolution is accelerating investment in cloud infrastructure. Global AI infrastructure spending is projected at $200 billion in 2025—up +50% year-over-year—driving explosive demand for data centers, GPUs, and networking equipment, with annual growth of +35% expected through 2030 to expand the market to $1 trillion.
Big tech AI investment overview: Microsoft is investing $50 billion annually in AI, focused on expanding Azure data centers and purchasing more than 100,000 NVIDIA GPUs in partnership with OpenAI. Google is investing $45 billion annually in AI, developing its own TPUs (Tensor Processing Units) to reduce NVIDIA dependency, and using TPU v5 to train its Gemini AI models. Amazon is investing $40 billion annually in AI to expand AWS AI services (SageMaker, Bedrock), and has strengthened its entry into the generative AI market through its investment in Anthropic (Claude AI). Meta is investing $30 billion annually in AI, focused on developing its open-source Llama AI models and using AI-driven recommendation algorithms for Reels and Instagram to maximize advertising revenue.
Key AI infrastructure beneficiaries: NVIDIA holds a 90% share of the AI GPU market, maintaining a near-monopoly position; margins exceed $10,000 per H100 GPU, driving high profitability; and 2025 revenue is forecast at $120 billion (+100%), sustaining explosive growth. Broadcom is enhancing data center connectivity speeds with AI networking chips (Jericho, Tomahawk), diversifying into custom AI chip production (manufacturing partner for Google's TPU), and forecasting AI-related revenue of $20 billion in 2025—up +80% year-over-year. AMD has emerged as a credible NVIDIA competitor with its MI300 GPU, leveraging price competitiveness (MI300 is roughly 30% cheaper than the H100) to gain market share, and forecasts AI-related revenue of $4 billion in 2025—a +300% surge year-over-year. TSMC holds a 60% share of the AI chip foundry market, producing AI chips for NVIDIA, AMD, and Apple under near-exclusive arrangements, advancing chip performance with 3nm process technology, and expects AI-related revenue of $50 billion in 2025 (50% of total revenue).
AI investment ETFs: BOTZ (Global X Robotics & AI ETF) invests in 40 global AI and robotics companies; top holdings include NVIDIA 12%, Intuitive Surgical 8%, and ABB 6%; expense ratio 0.68%; up +35% year-to-date in 2025. ROBO (ROBO Global Robotics and Automation ETF) is broadly diversified across 80 robotics and automation companies, covering manufacturing, healthcare, and logistics automation—a broader scope than pure AI; expense ratio 0.95%; up +28% year-to-date in 2025. CLOU (Global X Cloud Computing ETF) invests in 30 cloud infrastructure companies; top holdings include Amazon (AWS) 10%, Microsoft (Azure) 9%, and Salesforce 8%; expense ratio 0.68%; up +32% year-to-date in 2025.
AI ETF investment strategy: allocate 5–10% of the portfolio to AI themes to capture long-term growth opportunities while recognizing elevated valuation risk. Since QQQ already includes NVIDIA, Microsoft, and Amazon, avoid double-counting and limit combined QQQ + AI ETF exposure to 60% or less. Take partial profits to manage risk if AI bubble concerns arise (P/E above 50x); reduce the weighting if AI earnings momentum decelerates (big tech AI revenue growth slows). From a long-term investment perspective (5+ years), AI is a general-purpose technology like electricity or the internet with certain long-term growth prospects—hold through short-term volatility, and check AI revenue growth rates at each quarterly earnings release; maintain the position as long as growth stays above +20%.
Use the rebalancing calculator to set a target AI ETF weighting (e.g., 8%) and sell the excess if an AI surge pushes it above 12% to lock in gains. Use the asset allocation calculator to simulate your total portfolio loss in an AI bubble collapse (-50%) across AI ETF scenarios of 5%, 10%, and 15% to determine an AI sector allocation that matches your personal risk tolerance and conviction in AI growth, and manage thematic investment risk accordingly.
Tech Stock Valuation and Rebalancing Strategy
The sustained tech rally has increased valuation pressure. The Nasdaq 100 at 33x P/E is 32% above its historical average (25x)—below the 2000 dot-com bubble (60x P/E) and the 2021 pandemic bubble (40x P/E), but carrying correction risk nonetheless; if interest rates rise, high-valuation growth stocks face sharp price declines as discount rates increase. On a sector-by-sector basis: big tech (FAAMG) at 30x P/E commands a premium on AI growth expectations, but a PEG of 1.5 when accounting for an earnings growth rate of +20% is a reasonable level. Semiconductors (SOXX) at 35x P/E are justified by exploding AI demand, but carry significant crash risk in an economic slowdown. Software (IGV) at 40x P/E faces overvaluation concerns due to slowing SaaS growth and is the sector most vulnerable to rising interest rates.
Valuation risk indicators: the Buffett Indicator (market cap / GDP) is at 200%, near its historical high of 220% in 2021, signaling that the broad equity market has entered an overheated zone—a drop below 150% would represent a buying opportunity. The Shiller CAPE ratio (cyclically adjusted P/E) is at 32x, 88% above its historical average of 17x, pointing to lower long-term return expectations; a drop below 25x would improve long-term investment attractiveness. The Fear & Greed Index is at 75 (Extreme Greed), indicating overheated investor sentiment—a sign of an impending correction. A drop below 25 (Extreme Fear) would signal a bottom-buying opportunity.
Tech stock rebalancing strategy: setting target allocations is critical. Investors in their 40s (growth-oriented) should allocate 60% to tech: QQQ 50% and SOXX 10%. Those in their 50s (balanced) should allocate 40%: QQQ 35% and SOXX 5%. Those in their 60s (stability-oriented) should allocate 20%: QQQ 20% and SOXX 0%. Rebalancing triggers: on a weighting deviation of ±10 percentage points, if QQQ surges from its 50% target to 60%, sell 10 percentage points and reallocate to bonds or defensive sectors. On a valuation basis, if the Nasdaq 100 P/E exceeds 40x, cut tech weighting by 10 percentage points to avoid overvaluation risk. On recession signals (unemployment rate up +0.5 pp, PMI below 48), cut tech weighting by 20 percentage points to reduce economic sensitivity.
Practical rebalancing example: starting portfolio of ₩100 million (QQQ ₩50M / 50%, SOXX ₩10M / 10%, AGG ₩25M / 25%, XLP ₩15M / 15%). Six months later—QQQ +20%, SOXX +25%, AGG -1%, XLP +3%—the portfolio grows to ₩109.95M (QQQ ₩60M / 54.6%, SOXX ₩12.5M / 11.4%, AGG ₩24.75M / 22.5%, XLP ₩15.45M / 14.1%). QQQ's weighting has risen 4.6 pp from its 50% target, but it remains within the ±10 pp band, so no rebalancing is required mechanically—however, with the Nasdaq 100 P/E rising to 36x and valuation pressure increasing, a preemptive rebalancing to cut QQQ to 45% is executed: sell QQQ to ₩49.48M (45%), buy AGG up to ₩30.24M (27.5%) and XLP up to ₩16.48M (15%), and reserve ₩4M in cash for bottom-buying on further corrections. The rebalancing effect: reducing tech weighting (66% → 56%) provides a proactive defense against valuation risk; expanding bonds and defensive sectors (40% → 42.5%) strengthens portfolio stability; holding cash (3.6%) enables opportunity capture on further corrections; and in a tech -20% correction, total portfolio loss decreases from -13.2% (before rebalancing) to -11.2% (after rebalancing).
Use the rebalancing calculator to set your target tech weighting and band, and check quarterly for weighting deviations. Use the asset allocation calculator to simulate total portfolio losses and long-term returns in a Nasdaq -30% correction across tech weighting scenarios of 40%, 50%, and 60% to maintain an optimal technology allocation suited to your age, risk tolerance, and valuation outlook—rebalancing regularly to manage overvaluation risk.
Conclusion
The tech rally continues, but valuation pressure and interest rate risk must not be overlooked. TQQQ should be used only as a short-term trading instrument, with long-term investing done via QQQ instead. The semiconductor sector is growing on AI demand, but its high cyclical sensitivity requires careful allocation management. Use the rebalancing calculator to check that your technology weighting has not grown excessive, and use the asset allocation calculator to simulate portfolio losses from a tech correction to proactively manage valuation risk.
