To The Moon

AI hyperscaler capex is set to nearly triple to $1.4T by 2027, this might fueled a multi-year demand wave for semiconductors and infrastructure.

So in this article, I would like to share my thoughts about positioning for a multi-year AI/hyperscaler capex cycle. We will be looking at these three ETFs (SMH, SOXX, WTAI) with their key facts and exposures, also tried to see which practical pairing strategies (portfolio mixes), tradeoffs, and suggest guardrails (rebalancing, risk controls, implementation notes).

1) The Demand Thesis (What Is Driving The Idea)

Several institutional reports and news pieces project very large AI / data-center / hyperscaler infrastructure spending over the next few years — e.g., Bain and others argue the data-centre + AI hardware/software market could approach ~$1.4T by 2027, and Citigroup/others have similar multiyear trillion-dollar forecasts. This is the capex tailwind that would lift semiconductor manufacturers, equipment makers, memory vendors and infrastructure suppliers.

2) Quick, sourced snapshot of the three ETFs (load-bearing facts)

SMH — VanEck Semiconductor ETF $VanEck Semiconductor ETF(SMH)$

Strategy: concentrated exposure to the largest liquid semiconductor names (MVIS US Listed Semiconductor 25 index).

Expense ratio / AUM (approx): ~0.35% expense, AUM ≈ $33–34B. Top weightings heavily favor $NVIDIA(NVDA)$, $Taiwan Semiconductor Manufacturing(TSM)$, $Broadcom(AVGO)$; NVDA ~18–19% and TSM ~9–10% as of early Oct 2025. SMH also includes equipment makers (ASML, LRCX, AMAT).

SOXX — iShares Semiconductor ETF $iShares Semiconductor ETF(SOXX)$

Strategy: tracks a semiconductor index with ~30–35 holdings (more US-centric than SMH’s index construction differences).

Expense ratio / AUM (approx): ~0.34% expense, AUM ≈ $14–16B. Top holdings include Broadcom, NVIDIA, AMD, Micron, Qualcomm — generally slightly more evenly spread than SMH (NVDA weight notably lower vs SMH).

WTAI — WisdomTree Artificial Intelligence & Innovation Fund $WisdomTree Artificial Intelligence and Innovation Fund(WTAI)$

Strategy: thematic AI & innovation fund (broad mix across software/platforms, cloud, semis, memory vendors, and some international names). ~0.45% expense, AUM ≈ $400M, ~70–80 holdings. Top holdings include Alphabet, Broadcom, NVIDIA, Microsoft, Meta (each at low single-digit weights — it’s much broader).

3) How these ETFs complement each other (what each brings)

SMH = deep semiconductor concentration (chip designers + fabs + equipment). Great if you want direct exposure to chip makers and the supply chain that benefits when hyperscalers scale compute. (Higher single-name concentration risk — e.g., NVDA large weight.)

SOXX = semiconductor exposure with slightly different index rules / weights — often a bit more balanced across multiple chip companies (AMD, Broadcom, Micron, etc.). Good as a “core” chip sleeve with good liquidity.

WTAI = thematic AI & platform exposure — includes software, cloud, AI platform winners (Alphabet, MSFT, Meta) and some hardware names. This gives you demand-side exposure (hyperscalers and AI platform beneficiaries) rather than just supply-side.

Pairing semiconductors (supply) with WTAI (demand/platforms) is appealing because it captures both sides of the secular cycle: the companies buying and integrating AI (cloud + apps) and the companies building chips, memory and fabs those buyers need.

4) Concrete pairing / portfolio ideas (three risk profiles)

All mixes assume these are satellite positions inside a broader portfolio (i.e., not your entire portfolio). They also assume dollar-cost averaging (DCA) into a multi-year theme to reduce timing risk.

A — Growth / aggressive (aiming to capture the full AI capex upside)

• 50% SMH / 30% WTAI / 20% SOXX

• Rationale: overweight SMH to capture the manufacturing + equipment + Nvidia concentration (big wins if NVDA/TSMC & equipment makers keep executing), WTAI to capture platform upside, SOXX for additional chip diversification.

• Pros: highest upside if hyperscaler capex keeps accelerating.

• Cons: largest volatility & single-name concentration (NVDA, Broadcom, TSMC risk).

B — Balanced thematic (diversified AI exposure, lower single-name risk)

• 40% SOXX / 40% WTAI / 20% SMH

• Rationale: SOXX as the core semiconductor sleeve (less NVDA concentration vs SMH), WTAI as demand/platform exposure; smaller SMH allocation for extra equipment/foundry tilt.

• Pros: smoother ride with meaningful upside from both demand and supply.

• Cons: less direct leverage to a pure chip rally than the aggressive mix.

C — Conservative / hedge-aware (AI theme without extreme concentration)

• 60% broad market or large-cap tech (not asked but recommended) + 25% WTAI + 15% SOXX (or SMH)

• Rationale: keep core equities for stability, add AI thematic via WTAI and a smaller semiconductor sleeve to participate in capex growth with less overall portfolio beta.

• Pros: lower drawdown risk if AI capex disappoints.

• Cons: lower upside capture.

5) Tactical & Risk Management Rules (Implementation Notes)

Watch concentration (NVDA/AVGO/TSM): SMH can have very large single-name weights; if you dislike single stock risk, prefer SOXX or trim SMH allocation. (See SMH NVDA ~18–19% vs SOXX NVDA ~7%.)

Pair supply + demand: owning both semiconductor ETFs and WTAI captures capex from both sides — buyers (cloud, AI platforms) and suppliers (chips, fabs, equipment). That reduces one-sided risk (e.g., if hyperscalers pause purchases but platform revenues hold).

Valuation vigilance: thematic funds often trade at higher P/E multiples; review forward P/E and whether expectations are baked into prices (WTAI shows higher P/E metrics). Rebalance if thematic premium becomes extreme.

Rebalance on flows/news: big earnings / capex updates from hyperscalers (Microsoft, Google, Amazon) or supply shocks (TSMC capacity, export rules, ASML deliveries) should trigger reassessment. Use a rule like calendar rebalance (quarterly) + event rebalance (if allocation drifts >5–7%).

Execution: if AUM / liquidity matters, SMH and SOXX are very liquid; WTAI’s AUM (~$400M) and average volume are smaller — use limit orders or DCA to avoid market impact.

6) Potential risks & what could go wrong

Capex slows or front-loads: If hyperscalers push most spending into 2024–2025 then sharply slow, suppliers could see a cyclical downcycle. (Wall Street analysts have flagged downside scenarios.)

Single-name dominance: If NVDA (or another mega weight) underperforms, heavily concentrated ETFs (especially SMH) will suffer disproportionately.

Geopolitical / supply constraints: export controls, trade barriers (US-China semiconductor rules) and foundry capacity limits (TSMC) can change winners and losers quickly.

Thematic valuation risk: WTAI and other AI theme funds can reprice quickly if growth forecasts disappoint.

7) Quick Checklist Before Taking Action

1. Confirm current holdings & weights (ETF pages / fund facts — numbers above are as of Oct 2025).

2. Decide our risk bucket (Aggressive / Balanced / Conservative) and set target allocations and rebalancing rules.

3. Use DCA to enter a multi-year theme (e.g., weekly or monthly buys over 6–12 months) to avoid timing risk.

4. Monitor 3 signals: hyperscaler capex updates (earnings commentary), major inventory builds at chip makers, and regulatory/geopolitical headlines.

8) Short Recommendation Summary

If you believe hyperscaler capex truly goes multi-trillion over several years, a paired approach makes sense: use SMH or SOXX as the supply sleeve (chips, fabs, equipment) and WTAI as the demand/platform sleeve (cloud + AI software/platform winners).

For most investors we would favor SOXX + WTAI or a blended SMH+SOXX+WTAI mix rather than only SMH (to limit extreme single-name concentration). Size the theme as a satellite allocation (e.g., 5–15% of total portfolio depending on risk appetite), dollar-cost average, and rebalance on set rules.

In the next section, we ran a simple, transparent 3-year backtest using each ETF provider’s published 3-year annualized total return (so we used fund-level 3-yr CAGR numbers rather than raw daily series). That gives a clean, quick comparison of how a buy-and-hold portfolio composed of those ETFs would have performed over the last 3 years (no rebalancing).

Important — Methodology & Caveats

Inputs: 3-year annualized returns (CAGR) from the ETF issuers / fund factsheets as of 30-Sep-2025:

• SMH (VanEck) — 3-yr annualized NAV return 53.34%.

• SOXX (iShares) — 3-yr annualized NAV return 28.13%.

• WTAI (WisdomTree) — 3-yr annualized NAV/market return ~26.6%.

• For the conservative portfolio I used SPY 3-yr annualized ~24.58% (market proxy).

Calculation: assume an initial $1 split by each portfolio weight, buy-and-hold for 3 years. Each leg grows by (1 + annual_rate)^3; final portfolio value = sum(weight × leg_final). From that I compute the 3-yr cumulative return and the implied portfolio annualized return (CAGR).

Limitations: this is not a full daily-series backtest (so it does NOT compute exact historical max drawdowns, timing-based realized volatility, or path-dependent metrics).

To compute accurate historical drawdowns, intraday/daily price series (or monthly closes) are required.

Results — Buy-and-Hold Over the Last 3 Years (Based on 3-yr Annualized Returns Above)

Portfolios tested (weights) and results (per $1 initial):

Aggressive — 50% SMH / 30% WTAI / 20% SOXX

• Final value after 3 years: $1.4265

• 3-yr cumulative return: +183.22%

• Implied annualized return (CAGR): 42.65%

Balanced — 40% SOXX / 40% WTAI / 20% SMH

• Final value after 3 years: $1.3701

• 3-yr cumulative return: +137.42%

• Implied annualized return (CAGR): 37.01%

Conservative (thematic sleeve inside core) — 60% SPY / 25% WTAI / 15% SOXX

• Final value after 3 years: $1.3369

• 3-yr cumulative return: +98.29%

• Implied annualized return (CAGR): 33.37%

• (Used SPY 3-yr annualized ≈ 24.58% as the broad-market core).

Interpretation: the heavy-SMH portfolios (large SMH weight) would have delivered the largest historical returns over the past 3 years because SMH’s 3-yr CAGR was very high (driven by mega-cap winners).

The balanced mix reduces single-name / concentration upside but still produces strong 3-yr returns. The conservative mix (core + thematic sleeve) materially reduces portfolio CAGR while keeping participation in the AI theme.

About Drawdowns

Why we did not compute an exact historical max drawdown: published 3-yr CAGRs do not contain path information (peaks and troughs). Real drawdowns require daily (or monthly) price history for each ETF so we can build the combined time series and compute peak-to-trough losses.

Quick proxy note: semiconductors and AI theme ETFs have been volatile (3-yr SDs often in the 25–35% range; individual short-term drawdowns exceed 20–30% in stress months). For example, SOXX’s fact sheet shows elevated 3-yr vol and material short-term drawdowns in some periods.

Summary

With AI hyperscaler capital expenditure projected to surge towards $1.4 trillion by 2027, investors can strategically position themselves to capture this multi-year growth wave. A potent strategy involves pairing core semiconductor ETFs with more diversified AI funds to harness the explosive demand for both chips and the broader infrastructure.

This approach allows investors to build a foundational position in the "picks and shovels" of the AI revolution while gaining exposure to companies enabling AI across various sectors.

Analysis of Top AI-Related ETFs:

• VanEck Semiconductor ETF (SMH): A highly concentrated fund, SMH provides aggressive exposure to the largest global semiconductor companies. Its significant weighting in industry giants like NVIDIA and Taiwan Semiconductor Manufacturing Company (TSMC) makes it a direct play on the high-performance chips powering AI data centers. Its top-heavy nature offers high-beta exposure, ideal for capturing the core of the AI chip demand.

• iShares Semiconductor ETF (SOXX): Offering a broader, U.S.-focused approach, SOXX holds a more diversified portfolio of semiconductor companies, including those involved in design, manufacturing, and equipment. While still concentrated in top names like NVIDIA and AMD, its wider diversification can help mitigate single-stock risk compared to SMH, appealing to investors seeking robust but slightly less concentrated exposure.

• WisdomTree Artificial Intelligence and Innovation Fund (WTAI): This ETF provides a more thematic and diversified approach. WTAI invests not just in chipmakers but also in companies leveraging AI in software, hardware, and technology services. By including companies that use AI to innovate, it offers a broader capture of the entire ecosystem beyond just the foundational hardware. Pairing WTAI with SMH or SOXX can balance the direct semiconductor bet with exposure to companies applying the technology, potentially smoothing volatility.
