Summary
- Historic capital inflows continue to flood into major ETFs tracking the Philadelphia Semiconductor Index, further intensifying the global concentration of capital into the AI hardware value chain.
- In April 2026 alone, the SMH and SOXX ETFs saw a combined record-high inflow of $5.5 billion, maintaining their upward rally in May and solidifying their place at the absolute center of global passive liquidity.
- The domestic Korean market is also reacting sensitively to changes in the external liquidity environment, driven by the launch of single-stock leverage ETFs focused on large-cap semiconductor stocks and anticipation of inclusion in global indices.
Market Overview
As of June 2, 2026, the global semiconductor market maintains strong upward momentum driven by accelerated AI data center investments and a severe supply shortage of High Bandwidth Memory (HBM).
On this day, the domestic Korean financial market closed with the KOSPI at 8,801.49 and the KOSDAQ at 1,026.03. The Nasdaq closed at 27,086.81, and the USD/KRW exchange rate finished at 1,519.30 won.
Recently, the newly launched single-stock leverage ETFs for Samsung Electronics and SK Hynix in Korea quickly absorbed market capital upon listing, acting as a "liquidity black hole" that drove short-term volatility in the KOSPI.
As the indices continue to run high, Daily Stock's proprietary Fear & Greed Index analysis showed a 'Neutral (59.1)' reading for the KOSPI and a 'Neutral (59)' reading for the Nasdaq, reflecting cautious investor sentiment.

Financial Analysis
The landscape of the global semiconductor ETF market in the first half of 2026 is clearly divided between economies of scale and niche market targeting.
SMH (VanEck Semiconductor ETF), the most representative semiconductor passive vehicle, maintains its industry leadership with assets under management (AUM) reaching approximately $68 billion.
SOXX (iShares Semiconductor ETF) follows with an AUM of about $38.4 billion. The record inflows into these two ETFs in April further consolidated liquidity within the semiconductor sector.
Additionally, the newly listed pure-play memory ETF 'DRAM', which launched in April, showed rapid growth by surpassing $5 billion in AUM just five weeks after its release.
| ETF Name | Tracking Index & Characteristics | Assets Under Management (AUM, as of late May 2026) | Expense Ratio | Key Areas of Focus |
|---|---|---|---|---|
| **SMH** | MVIS US Listed Semiconductor 25 Index | Approx. $68 billion | 0.35% | Global large-cap semiconductor stocks & heavy Nvidia weight |
| **SOXX** | ICE Semiconductor Index (formerly tracked Philadelphia Semi Index) | Approx. $38.4 billion | 0.34% | Diversified investment in US-listed semiconductor firms |
| **DRAM** | World's first pure-play memory semiconductor thematic ETF | Surpassed approx. $5 billion | 0.65% | Concentrated investment in Micron, SK Hynix, and Samsung Electronics |
Valuation
The Philadelphia Semiconductor Index (SOX) showed some of its strongest overbought signals since historical bubble bursts, with its Relative Strength Index (RSI) temporarily surpassing 85 in late May.
As the 10-year US Treasury yield (US10Y) fluctuates amid uncertainty over global monetary policy, the sensitivity of high-multiple tech stocks to rising risk-free rates remains at an all-time high.
While annual CAPEX projections by Big Tech firms—a key indicator of global AI infrastructure investment—remain robust, high valuations make them increasingly sensitive to interest rate volatility.
Ultimately, the justification for current valuation multiples depends on whether Nvidia's next-generation chip revenues and the guidance of major foundries can consistently meet the high expectations of the market.
Expert & Institutional Analysis
Global investment institutions interpret the powerful flow of funds into semiconductor ETFs as a reflection of a structural paradigm shift rather than mere speculative demand.
According to J.P. Morgan, retail investors in 2026 have overwhelmingly preferred semiconductor ETFs over cryptocurrency ETFs, emerging as a leading force in the market.
Domestically, Mirae Asset Securities estimated that if SK Hynix successfully completes its US ADR listing and is included in the Philadelphia Semiconductor Index (PHLX), it could trigger approximately $2.79 billion in new passive buying.
Han Ji-young, a researcher at Kiwoom Securities, raised concerns over short-term volatility due to concentrated capital in the recently listed single-stock leverage ETFs, but noted that they could serve as a positive channel to inject liquidity into the market over the long term.

Risk Factors
The most significant risk is the potential for a "delay in AI monetization" among Big Tech companies that are currently deploying astronomical sums of capital.
If actual business model profitability fails to support the scale of AI infrastructure investments, it could lead to downward guidance revisions across the entire hardware supply chain.
Additionally, bottlenecks in semiconductor manufacturing and packaging processes resulting from global geopolitical tensions remain an ongoing risk that could trigger abrupt passive capital outflows.
Lastly, if the US 10-year Treasury yield (US10Y) breaks new highs and higher interest rates persist, downward multiple compression for growth stocks will be inevitable.
Investment Perspective
The unprecedented volume of liquidity flowing into Philadelphia Semiconductor ETFs serves as a sturdy backstop, demonstrating the robust expansion of the AI hardware ecosystem.
However, given the short-term overbought RSI signals and the high volatility of domestic and international leveraged products, a staggered dollar-cost averaging approach is more appropriate than aggressively chasing the rally.
For investors who trust the long-term growth trajectory, utilizing large-cap passive ETFs (SMH, SOXX) to offset the earnings volatility of individual stocks could be an excellent alternative.
It is essential to monitor shifts in macroeconomic indicators like the US Dollar Index (DXY) and the Volatility Index (VIX) to gauge the continuity of these capital inflows.
Investor Checklist Q&A
Q1. Which ETF is better to choose between SMH and SOXX?
A1. Because SMH has a higher concentration in specific leading companies like Nvidia, its performance tends to be maximized during rallies of leading stocks. On the other hand, SOXX offers relatively diversified exposure across the US semiconductor value chain, making it more suitable for stability-seeking investors.
Q2. What is the key driver behind the recent record-breaking inflows into semiconductor ETFs?
A2. As Big Tech companies sharply increased their capital expenditures (CAPEX) for AI infrastructure, their earnings performance improved visibly. This prompted global passive and retail capital to concentrate heavily on the semiconductor sector, which is backed by concrete tangible profits.
Q3. What is the impact of the large-cap semiconductor leverage ETFs listed in the Korean market?
A3. In the short term, they have amplified index volatility by heavily drawing capital into top market-cap stocks like Samsung Electronics and SK Hynix. However, they have also contributed to bringing new liquidity into the market and increasing the number of educated investors.
Q4. Why does a rise in the US 10-year Treasury yield (US10Y) put downward pressure on semiconductor stock multiples?
A4. Rising Treasury yields increase the discount rate used to calculate the present value of future corporate earnings. This leads to downward revisions of fair stock prices for high-valuation growth sectors like semiconductors.
Q5. How does anticipation around SK Hynix's inclusion in the Philadelphia Semiconductor Index affect liquidity?
A5. If the company successfully lists US ADRs and gains index inclusion, it will trigger mechanical buying demand (estimated at around $2.79 billion) from global passive funds tracking the index, creating a highly stable liquidity base.
