Memory Semi Tug-of-War: Retail Ants vs Foreign Institutional Selling

March 15, 2026

MUAs the primary U.S.-listed competitor in the memory semiconductor industry, Micron is the most direct proxy for the 'supercycle' and High Bandwidth Memory (HBM) demand trends affecting Samsung and SK Hynix.
NVDANVIDIA is the leading consumer of the HBM capacity mentioned as being 'sold out through 2026,' making it a central beneficiary of the structural growth in the memory market.
AMATAs a top provider of semiconductor manufacturing equipment, Applied Materials benefits from the capital expenditure and capacity expansions undertaken by Samsung and SK Hynix to meet supercycle demand.

Now let me search for a few more specific data points to round out the analysis.Now I have comprehensive data to write the report. Let me compile this into a thorough analysis.

1. πŸ”‘ Key Points

  • Korean retail investors ("Donghak Ants 3.0") have deployed over β‚©8.5 trillion ($6+ billion) into Samsung Electronics and SK Hynix in a single week during the March 2026 oil crisis, directly absorbing massive foreign institutional selling of β‚©10.2 trillion ($7.3 billion) β€” creating the starkest retail-vs-institutional standoff in Korean market history.

  • The memory semiconductor supercycle fundamentals remain intact despite the oil shock: forward P/E ratios of ~4.5x for SK Hynix and ~7x for Samsung suggest the selloff has disconnected prices from earnings trajectories that Bank of America calls "a supercycle similar to the boom of the 1990s," with HBM capacity sold out through 2026.

  • Historical precedents from the 1990 Gulf War, 2020 COVID crash, and 2022 Russia-Ukraine energy shock consistently show that oil-driven macro selloffs in fundamentally sound semiconductor stocks resolve within 30–90 days β€” and that retail investors who buy during panic (as the Donghak Ants did in March 2020) tend to be vindicated when geopolitical catalysts fade.


2. The Tug-of-War: Korean Retail Conviction vs. Foreign Institutional Retreat

This section maps the epic capital flow divergence between Korea's domestic retail investors and global institutional money managers during the March 2026 oil shock.

  • Korean retail investors bought a record β‚©7.543 trillion in a single day (February 27) to absorb the largest-ever single-day foreign selloff of β‚©7.03 trillion.
  • Foreign investors dumped approximately β‚©10.2 trillion ($7.3 billion) from the KOSPI in just the first nine days of March 2026.
  • The government deployed a historic β‚©100 trillion ($68.3 billion) financial market stabilization fund, the largest emergency intervention in Korean history.

2.1 The Scale of Foreign Selling

The foreign institutional exodus from Korean equities during the early March 2026 oil shock was staggering. According to the Korea Exchange, foreign investors recorded net sales of approximately 10.2 trillion won ($7.3 billion) on the KOSPI from the start of March through March 9. The selloff reflects global investors reducing exposure to risky assets as Middle East tensions escalated.

This was not unprecedented in isolation β€” foreign investors had previously unloaded a record 7.12 trillion won ($5 billion) worth of shares in a single day in late February β€” but the velocity and concentration into memory semiconductor names was historically unusual. Samsung and SK Hynix both dropped by around 20% since U.S. strikes on Iran began.

The selling pattern reveals a critical dynamic: as Samsung Electronics and SK Hynix rose during the rally, foreigners exceeded their required Korea allocation and sold the excess, and with the exchange rate jumping, investors with profit-taking motives likely sold as well.

2.2 The Retail Wall of Money

Against this wave of foreign selling, Korean retail investors β€” the modern incarnation of the "Donghak Ants" β€” mounted an extraordinary defense. Retail investors purchased approximately 4.31 trillion won ($3.1 billion) worth of Samsung Electronics shares and about 1.93 trillion won ($1.4 billion) of SK Hynix during the week of March 6-13, making them the top two net purchases by individuals.

On February 27, foreign investors recorded their largest-ever single-day net selling on the KOSPI at 7.03 trillion won, while individual investors net bought 7.543 trillion won, supporting the index. Retail investors' average daily net purchases on the KOSPI market reached 819.1 billion won ($566 million) in February.

Even during the worst of the crash, the retail conviction held firm. On the day war and oil price concerns triggered panic in KOSPI, with both markets triggering program trading curbs and the KOSPI activating a circuit breaker, retail investors alone bought 4.6 trillion won.

2.3 How Today's "Smart Ants" Differ from 2020

Securities analysts say today's retail investors differ qualitatively from the "Donghak Ants" who drove the market rebound during the COVID-19 pandemic crash in 2020. Individual traders have evolved into "Smart Ants" who analyze global trends and use ETFs for diversified investing, moving beyond short-term bets on individual stocks.

The new wave is not just buying blindly. Analysts interpret the robust buying by individual investors as a reflection of expectations for structural improvements in the Korean stock market, driven by pro-capital market policies under the Lee Jae-myung administration and improved earnings at semiconductor companies. This represents a more sophisticated thesis than mere patriotic fervor.


3. The Oil Shock: Korea's Achilles Heel

This section examines why South Korea is uniquely vulnerable to Middle Eastern oil disruptions and how this vulnerability amplifies the divergence between retail and institutional investor behavior.

  • South Korea relies on the Strait of Hormuz for ~70% of its crude oil and ~30% of its natural gas imports.
  • The KOSPI suffered a historic 12.64% single-day crash on March 4, 2026 β€” the worst in its entire history.
  • Circuit breakers were triggered twice in March, a frequency not seen since August 2024.

3.1 The Strait of Hormuz and Korea's Energy Dependency

The country imports 70% of its crude oil from the Middle East, and 95% of those shipments pass through the Strait of Hormuz. South Korea, with its high dependence on imported energy (approximately 70% of its oil and 20% of its LNG), is particularly exposed to sustained spikes in oil prices.

This dependency creates a vicious feedback loop for Korean equities. The nation's manufacturing sector, contributing 40-45% of GDP, is energy-intensive. The Korean won experienced significant depreciation, weakening past 1,500 per U.S. dollar for the first time since the 2009 financial crisis, which exacerbates import costs and fuels inflation fears. The combination of higher energy prices and a weaker currency creates a challenging environment for the Bank of Korea.

3.2 The March 2026 Crash Sequence

The timeline of destruction was devastating:

DateEventKOSPI Impact
Feb 27Record foreign selling β‚©7.03T; KOSPI peaks near 6,347-1.0%
Mar 3Markets reopen after holiday; Hormuz blockade confirmed-7.2%
Mar 4"Black Wednesday" β€” worst day in KOSPI history-12.6%
Mar 5Government deploys β‚©100T stabilization fund+9.6%
Mar 9Second circuit breaker triggered-5.96%
Mar 10Trump signals Iran war will "end soon"+5.35%

South Korea's benchmark KOSPI index suffered a cataclysmic 12.1% collapse on March 4, marking the single worst trading day in the nation's history. The "Black Wednesday" rout was triggered by a rapid military escalation in the Middle East, culminating in the closure of the Strait of Hormuz.

3.3 The Semiconductor-Oil Nexus

The connection between oil prices and Korean memory stocks runs deeper than most investors appreciate. South Korea's semiconductor fabs run 24/7, and a significant portion of the electricity they consume comes from LNG-fired power plants. When natural gas prices spike, the operating costs for these energy-intensive facilities follow. This is the direct link between the Middle East turmoil and the chipmakers.

Beyond direct energy costs, the "high dependency" of the U.S. on crude oil "indicates significantly higher costs for AI datacenters" which are roughly three-to-five times "more power-hungry than regular data centers." This "could significantly increase the total cost of ownership (TCO) for hyperscalers, thereby posing a threat towards AI infrastructure adoption."

Additionally, more than 25% of the world's helium supply would be taken off the market by an extended shutdown of the Strait of Hormuz, and helium is irreplaceable in semiconductor lithography.


4. The Memory Supercycle Thesis: Why Retail Investors May Be Right

This section analyzes the fundamental case for Samsung and SK Hynix, explaining why the structural demand story may ultimately override macroeconomic headwinds.

  • Bank of America defines 2026 as a "supercycle similar to the boom of the 1990s," forecasting global DRAM revenue to surge 51% year-over-year.
  • SK Hynix's forward P/E of ~5.5x is 81% below the semiconductor industry median of ~29x.
  • HBM production capacity is completely sold out through 2026, with multi-year contracts already locked in.

4.1 The Unprecedented Supply-Demand Imbalance

The memory semiconductor market is experiencing what many analysts describe as the most severe supply crunch in history. Macquarie's Kim stated that the industry is experiencing "the worst memory crunch in history and see no signs of easing supply in the next 2 years."

Bank of America defines 2026 as a "supercycle similar to the boom of the 1990s," forecasting global DRAM revenue to surge by 51% and NAND by 45% year-over-year, with Average Selling Prices (ASP) rising by 33% and 26%, respectively. BofA estimates the 2026 HBM market to reach $54.6 billion, a 58% increase from the previous year.

The supply constraint is structural, not temporary. SK Hynix reported during its October earnings call that its HBM, DRAM, and NAND capacity is "essentially sold out" for 2026, while Micron recently exited the consumer memory market entirely to focus on enterprise and AI customers.

4.2 Valuations: The Disconnect That Favors the Bulls

Even after the extraordinary rally through early 2026, Korean memory stocks trade at valuations that are dramatically cheap relative to their earnings power.

According to Goldman Sachs, SK Hynix's price-to-earnings ratio (PER) stands at 4.5 times and price-to-book ratio (PBR) at 1.7 times based on next year's projected earnings, making the valuation still attractive. KB Securities raised its target price to 1.7 million won, a 21% increase, stating: "Despite earnings growth of four times, the price-to-earnings ratio remains at 4.3 times, suggesting high potential for revaluation as a high-growth value stock."

SK Hynix's forward P/E ratio is 5.56, while the Semiconductors industry median Forward PE Ratio is 28.86. SK Hynix's value of 5.56 is 80.7% below this industry median.

Forward P/E Ratio Comparison (March 2026)

4.3 The Price Hike Engine

Memory pricing continues to accelerate despite the geopolitical turmoil. TrendForce expects conventional DRAM contract prices to rise around 55–60% in Q1 2026, with NAND flash contract prices up about 33–38% over the same period. Server DRAM is forecast to climb by more than 60%.

Samsung Electronics and SK Hynix have reportedly hiked prices for fifth-generation high-bandwidth memory by nearly 20% for 2026 deliveries, as soaring demand for AI accelerators outstrips supply.

Goldman Sachs raised its operating profit forecast for Samsung Electronics this year from 18.1 trillion won to 23.9 trillion won β€” more than five times last year's operating profit. Goldman Sachs projected Samsung Electronics' return on equity would reach a historical high of approximately 37%.

4.4 Why the Oil Shock May Not Derail AI Capex

The key bull argument is that AI datacenter spending β€” the primary driver of HBM demand β€” is not meaningfully sensitive to temporary energy price spikes. As Hana Securities analyst Kim Rok-ho noted: "Macro issues caused sharp declines in domestic markets and memory stocks. This is profit-taking unrelated to fundamentals, and the investment cycle for semiconductor equipment and materials companies remains intact."

CLSA maintained a positive outlook on the memory sector, raising price targets for both Samsung and SK Hynix. CLSA expects limited impact on memory supply chains and demand despite Middle East tensions, forecasting continued earnings improvements as pricing momentum persists.

Hyperscalers have committed hundreds of billions in AI infrastructure spending, and these commitments are contractually locked in. Samsung Electronics and SK Hynix struck a deal with OpenAI for the eventual supply of 900,000 DRAM wafers a month to meet the memory demands of its Stargate project.


5. Historical Precedents: Who Wins the Retail-vs-Foreign Tug-of-War?

This section examines every major instance of retail-vs-institutional divergence in Korean markets, with specific focus on oil-driven episodes.

  • In March 2020, Donghak Ants bought β‚©47.4 trillion as foreigners sold β‚©50 trillion β€” retail investors were massively rewarded as KOSPI more than doubled.
  • The 1990 Gulf War saw global stocks recover within months of the conflict's resolution, with semiconductor demand barely dented.
  • Academic research suggests Korean retail investors historically underperform institutions, but the 2020 and 2025–2026 cycles represent structural breaks from that pattern.

5.1 The 2020 Donghak Ants: Retail's Greatest Victory

The closest parallel to the current situation is March 2020. In March 2020, foreign and institutional investors sold off a combined $46 billion (50 trillion won) of the benchmark KOSPI, pushing the market down to 1,457.64 points. Ants countered, buying $43.58 billion (47.4 trillion won), propelling the KOSPI index over the 3,000 mark for the first time in history in January 2021.

The parallel is striking: foreign panic selling meets a wall of domestic retail conviction, with the market recovering to new highs. While foreign investors dumped some 7.23 trillion won of Samsung shares over two months in 2020, retail investors purchased 7.43 trillion won worth β€” five times more than institutional investors.

The critical difference today: the 2020 Donghak Ants were driven primarily by patriotic sentiment and the belief that COVID was temporary. Today's retail buyers have a concrete, quantifiable earnings thesis β€” the memory supercycle.

5.2 The Gulf War Playbook (1990-1991)

Wall Street is explicitly referencing the 1990 template. In 1990, oil surged roughly 135% to around $46 per barrel, the S&P 500 fell 16–18%, and then rebounded 26–29% in 1991 once the conflict ended and crude collapsed. The recession was mild and short-lived. Markets recovered quickly once the geopolitical trigger was removed.

Two events that prompted oil shocks resulted in double-digit stock market losses: the 1973 Yom Kippur War and Arab oil embargo, and in 1990 when Iraq invaded Kuwait. The S&P 500 traded down by 16.1 percent and 15.9 percent, respectively. During the Russia-Ukraine oil shock, the stock market declined "only" 7.4 percent.

The pattern is clear: oil shocks tied to military conflicts create V-shaped recoveries once the geopolitical catalyst resolves. Stocks regained their losses before the Gulf War was even over. Oil prices fell back to pre-war levels by April.

5.3 Academic Evidence: The Retail Investor Track Record

Here, intellectual honesty demands acknowledging the other side. Acadian Asset Management research shows that "Korean retail investors have an uncanny ability to buy securities that are about to crash." Individual investors incur substantial losses historically, while institutional ones gain from trade.

However, analysts note that while foreigners piled into large semiconductor names on expectations of a memory chip recovery during 2025, local investors chased internet and secondary-battery stocks that underperformed. This time is different in one crucial respect: Korean retail investors are buying the same semiconductor thesis that foreign institutions themselves built their KOSPI bull case on. The retail-institutional disagreement is not about what to own β€” it's about when to sell during a geopolitical shock.

5.4 The Pattern in Korean Market Crises

CrisisForeign ResponseRetail ResponseWho Won?Recovery Time
1997 Asian CrisisMassive sellingForced sellingForeigners (rebought cheap)~2 years
2008 GFCβ‚©28T net sellMixedForeigners (better timing)~18 months

2025 Tariff Shockβ‚©10B net sell AprilMissed initial rallyForeigners (led recovery)~3 months
2026 Oil Shockβ‚©10.2T net sellβ‚©8.5T+ net buyTBDOngoing

The key insight: retail investors win when the underlying asset has strong fundamentals and the shock is exogenous and temporary. They lose when the shock reveals genuine fundamental deterioration.


6. The Institutional Backstops: Government and NPS as Wildcards

This section examines the unprecedented government and pension fund interventions that tilt the balance in favor of the bulls.

  • President Lee Jae-myung deployed a β‚©100 trillion ($68.3 billion) market stabilization fund β€” the largest in Korean history.
  • The NPS, managing ~β‚©1,458 trillion ($1 trillion), raised its domestic equity allocation and is a natural buyer of any dip.
  • Corporate governance reforms β€” including mandatory treasury share cancellation β€” provide structural support for Korean stock prices.

6.1 The β‚©100 Trillion Stabilization Fund

South Korean President Lee Jae Myung ordered the rapid deployment of a 100 trillion won ($68.3 billion) financial market stabilization fund and urged officials to consider temporary fuel price caps. Speaking at an emergency Cabinet meeting, Lee warned that worsening geopolitical risks are undermining global economic stability.

However, the Korean Economic Daily reported the president as saying that the program was not designed to artificially prop up stock prices, warning that authorities must avoid purchasing equities in a way that distorts the market.

This fund is enormous β€” roughly equivalent to 4.5% of Korea's GDP β€” and its mere existence provides a floor under market sentiment. The fund's design focuses on preventing systemic financial stress (credit markets, corporate bond markets) rather than direct equity purchases, but the confidence effect is substantial.

6.2 The National Pension Service: The Elephant in the Room

The NPS, which managed about 1,427.7 trillion won ($990 billion) as of October 2025, lowered its target for overseas equities to 37.2% from an earlier goal of 38.9%. The fund raised its domestic stock allocation to 14.9% from 14.4%.

This seemingly modest reallocation translates into tens of billions of dollars flowing into Korean domestic equities. The NPS posted its strongest-ever annual return in 2025 as a semiconductor- and AI-driven stock rally boosted performance.

The NPS also began contributing to won stabilization. The NPS started doing "tactical hedging" in early December, which helped stabilize the market. Bloomberg reported that "South Korea's National Pension Service has recently started selling dollars to bolster the won."

6.3 Governance Reforms as a Structural Floor

Corporate governance reforms have helped fuel the rally, with parliament approving a bill requiring companies to cancel treasury shares. These reforms are not reversible by geopolitical events. These changes extended directors' fiduciary duties to all shareholders β€” not just the company itself. Minority investors gained legal standing to challenge harmful board decisions for the first time. This reform marked the most significant governance change in Korean history.


7. Risk Scenarios: What Could Go Wrong for the Retail Thesis

This section stress-tests the bull case, identifying the scenarios where foreign sellers would be vindicated.

  • A prolonged Hormuz closure (3+ months) could fundamentally alter Korea's GDP trajectory and earnings estimates.
  • Helium supply disruption could physically constrain semiconductor manufacturing capacity.
  • Consumer electronics demand destruction from rising memory prices could create a paradoxical demand cliff.

7.1 Scenario 1: Extended Energy Crisis

If the Strait of Hormuz remains closed for an extended period, the impact goes beyond stock prices. If the Strait of Hormuz remains closed for weeks or months, and oil prices climb past $100 a barrel, $68 billion may not be enough.

Korea's stock market plunged 18 percent in just four trading days β€” the worst drop since the 2008 financial crisis β€” and wiped out more than $500 billion in market value. In a prolonged crisis, even record earnings from memory chips could be overwhelmed by currency depreciation and energy cost inflation.

7.2 Scenario 2: Material Supply Chain Disruption

A prolonged regional conflict could "potentially disrupt chipmakers' manufacturing operations regarding sourcing materials like Helium and Bromine." For now, the impact "appears to be limited. However, a prolonged conflict could eventually lead to disruptions or require adjustments in the sourcing of key materials."

Energy disruptions also ripple directly into the semiconductor supply chain. Qatar alone ships roughly 30 percent of Taiwan's liquefied natural gas through the Strait of Hormuz. Taiwan currently holds only about 11 days of reserves. This matters because TSMC produces roughly 90% of the world's most advanced chips and consumes nearly 9% of the island's electricity.

7.3 Scenario 3: AI Capex Pullback

The bear case hinges on whether hyperscaler capex commitments hold under stagflationary pressure. The AI boom relies on aggressive datacenter investment. Such capital spending is potentially sensitive to economic shocks like higher energy costs. That could be especially true when it's financed by heavy borrowing.

IDC warned that the global smartphone market faces its largest year-on-year decline on record in 2026, with volumes forecast to fall 13% to their lowest level in a decade, driven by a "tsunami-like shock originating in the memory supply chain." However, this consumer demand destruction actually tightens the supply situation for AI-grade memory, paradoxically benefiting Samsung and SK Hynix's most profitable product lines.


8. The Verdict: Who Wins This Tug-of-War?

This section synthesizes all evidence to present a clear, opinionated assessment of the risk-reward setup.

  • The weight of historical evidence favors the retail thesis: oil-driven selloffs in stocks with strong fundamentals recover, typically within 90 days of resolution.
  • SK Hynix at a forward P/E of 5.5x during the strongest memory supercycle in 30 years represents a generational entry point β€” if the geopolitical shock is temporary.
  • The most probable outcome is a V-shaped recovery once conflict de-escalation becomes credible, with retail investors earning outsized returns.

8.1 My Assessment: Retail Wins (With Caveats)

The retail investors are likely right, but for the wrong timeline. The memory supercycle fundamentals are virtually unassailable β€” AI capex is not going to stop because of an oil shock. South Korea is dominant within the global market for DRAM. Together, Samsung and SK Hynix control 67% of the global DRAM market. Global demand for DRAM is so high right now that even if high oil prices forced them to increase their chip prices, it probably wouldn't dent their memory-chip businesses much.

The problem for retail is the path. Foreign institutional selling can create devastating drawdowns that wipe out leveraged retail positions. The introduction of single-stock leveraged ETFs β€” Korea's FSC approved single-stock leveraged ETFs for Samsung Electronics and SK Hynix β€” means that some retail investors face amplified losses that could force margin calls before the thesis plays out.

8.2 The Historical Pattern Speaks Clearly

Every oil-related military conflict since 1973 has followed the same pattern for non-energy sectors:

  1. Sharp initial selloff (weeks 1-4)
  2. Volatile bottoming process (weeks 4-8)
  3. Recovery to pre-crisis levels once resolution becomes visible
  4. New highs driven by pent-up demand and rate cuts

As Mirae Asset Securities analyst Kim Seok-hwan noted, "historically war has delivered only temporary shocks to financial markets and has not damaged the fundamental value of companies over the long term."

Historical data shows Korean markets typically recover within 30 days after circuit breakers trigger.

8.3 The Unique Risk-Reward Setup

What makes this episode unique is the magnitude of the valuation discount at which the selloff is occurring. Korean memory stocks were already cheap relative to their earnings trajectory before the crisis. The selloff has pushed them to absurd valuation levels.

Consider: Goldman Sachs projected SK Hynix would achieve operating margins in the high-70% range for DRAM and high-40% range for NAND this year. A company with 70%+ operating margins trading at ~5x forward earnings during a structural supply shortage is historically exceptional.

The risk-reward is asymmetric: if the conflict resolves (the base case, given Trump's comments about a quick resolution), the upside is 30-50% from current levels. If the conflict drags on, the downside is perhaps another 15-20%, but cushioned by the government stabilization fund and NPS buying.

KOSPI Index 2026 β€” Rally, Crash, and Recovery

9. The Structural Lesson: Chips Are the New Oil

This section examines the deeper irony of the current crisis β€” that memory semiconductors may be more strategically important than the oil that disrupted their stock prices.

  • Memory semiconductor revenue is projected to reach $200 billion in 2026, roughly 25% of all semiconductor revenue globally.
  • DRAM prices have been compared to precious metals in terms of scarcity, with prices surging 172% year-over-year.
  • The AI infrastructure buildout dwarfs anything in the energy sector in terms of capital deployment.

9.1 The Irony of the Selloff

There is a profound irony at the heart of this crisis. The world has learned that the price of chips is inextricably linked to the price of oil, and the security of one cannot exist without the security of the other.

Yet the very AI infrastructure that demands these memory chips is reducing the economy's long-term dependence on fossil fuels by enabling smart grids, autonomous systems, and clean energy optimization. The oil shock hurts memory stocks in the short term, but the AI revolution that drives their demand is a structural force that will outlast any geopolitical crisis.

Revenues for memory in 2026 are likely to be about US$200 billion, or 25% of total semiconductor revenues for the year. DRAM prices have surged 171.8% year-over-year as of Q3 2025, marking one of the sharpest price escalations in semiconductor memory history.

9.2 Why Foreign Sellers May Regret Their Timing

The foreign selling, while rational from a risk-management perspective, may prove to be the wrong trade. In 2025, foreign investors initially flooded out of Korean equities before flooding back in, turning the country from one of the most heavily sold markets earlier in the year into the most actively bought since September.

After dumping some $10.5 billion worth of Korean shares earlier in 2025, offshore investors purchased about $9.2 billion since autumn β€” the largest inflow among all surveyed markets. This pattern β€” panic sell first, panic buy back later β€” has been the consistent foreign institutional playbook in Korea.

Many in the market believe this episode may not significantly affect corporate earnings, leaving room for foreign investment to return and for the KOSPI to rebound. When the exchange rate approaches a peak, foreigners tend to reenter Korea seeking foreign-exchange gains.


10. Practical Implications for Investors

This section distills actionable insights for different investor types navigating the current setup.

  • Memory semiconductor fundamentals remain the strongest they have been in 30 years, making this selloff a potential generational buying opportunity.
  • Position sizing and avoiding leverage are critical β€” the volatility can destroy leveraged positions even when the thesis is correct.
  • The won/dollar exchange rate offers an additional alpha opportunity for foreign investors buying at depressed won levels.

10.1 For Aggressive Investors

The case for buying Samsung and SK Hynix during this panic is compelling. Forward P/E ratios of 5-7x during a supercycle are historically anomalous. With SK Hynix expected to maintain its leadership in AI memory products and ROE projected to exceed 80%, Goldman Sachs viewed positively the company's share buybacks and dividend expansion.

However, avoid leveraged products. The introduction of 2x leveraged ETFs on Samsung and SK Hynix creates the illusion of opportunity but dramatically increases the risk of permanent capital loss during a volatile recovery.

10.2 For Conservative Investors

The RISE Samsung Electronics SK Hynix Bond Mixed 50 fund attracted 121.5 billion won. This bond-hybrid ETF allocates 25% each to Samsung Electronics and SK Hynix, with the remaining 50% invested in high-quality bonds including short-term treasury securities. This product offers memory semiconductor exposure with a built-in buffer.

10.3 The Currency Dimension

Foreign investors face an additional consideration: the Korean won's extreme weakness. The Korean won weakened past 1,500 per U.S. dollar for the first time since the 2009 financial crisis. Buying Korean equities at depressed won levels creates a double-alpha opportunity β€” stock price recovery plus currency appreciation β€” when the crisis abates. This is exactly the pattern that drove massive foreign returns in late 2025.
