EWY vs MKOR: Weighing Passive Scale Against Active Flexibility in South Korea

Key Takeaways

• EWY is a large, passive, index-tracking fund with a low expense ratio and massive scale, while MKOR is a smaller, actively managed fund run by Matthews Asia.
• The two funds are highly concentrated in semiconductor leaders Samsung Electronics and SK Hynix, giving both meaningful exposure to the artificial intelligence (AI) memory-chip cycle.
• EWY carries a 0.59% expense ratio versus 0.79% for MKOR, a structural cost advantage that compounds over time.
• MKOR spreads its weight more evenly across single names and tilts toward industrials and smaller companies, while EWY leans more heavily into the two largest Korean tech giants.
• EWY offers far greater liquidity and roughly 80 holdings, whereas MKOR holds around 50 positions and a much smaller asset base.
• Tickeron AI Verdict: EWY is the favored ticker based on cost efficiency, scale, liquidity, and trend consistency in its core semiconductor exposure.

South Korea at a Crossroads

South Korea sits at the intersection of two dominant market narratives: the global AI build-out and a government-led push to improve corporate governance and shareholder returns. Two exchange-traded funds (ETFs) give U.S. investors direct access to this equity market: the iShares MSCI South Korea ETF (EWY) and the Matthews Korea Active ETF (MKOR). Although both target the same country, they represent fundamentally different investment approaches. EWY is a passive, index-replicating vehicle, while MKOR is an actively managed strategy that aims to outperform. Comparing them helps investors weigh cost, diversification, and management style within a single, concentrated market. I also checked this using Tickeron’s AI Screener to see how the holdings line up against broader industry peers.

The Passive Approach: EWY

EWY seeks to track the MSCI Korea 25/50 Index, a free-float-adjusted, market-capitalization-weighted benchmark covering the large- and mid-cap segments of the Korean equity market. Managed by BlackRock, it uses representative sampling and holds approximately 83 securities. Its top positions are Samsung Electronics and SK Hynix, which together account for roughly 45% of assets, followed by smaller weights in names such as SK Square, Samsung Electro-Mechanics, and KB Financial Group.

By sector, information technology dominates at about 54%, with industrials near 17% and financials around 11%. The fund's expense ratio is 0.59%, and its assets under management (AUM) run well into the tens of billions of dollars, making it among the most liquid and established single-country Korea funds. EWY is non-diversified and launched in May 2000.

The Active Approach: MKOR

MKOR is an actively managed ETF from Matthews Asia that seeks long-term capital appreciation by investing at least 80% of net assets in common and preferred stocks of South Korean companies. Launched as an ETF in July 2023, it adopted the track record of its predecessor mutual fund, the Matthews Korea Fund. The portfolio holds roughly 50 securities and is benchmarked against the MSCI Korea 25/50 Index, though it is not obligated to replicate it.

MKOR's largest holding, Samsung Electronics, sits near 20% of assets, but SK Hynix represents a much smaller weight of roughly 5%, reflecting the manager's decision to avoid mirroring the index's heavy concentration. Other notable positions include Samsung Electro-Mechanics, SK Square, PSK Inc., SK Inc., and KB Financial Group. Sector exposure is split between information technology at about 46%, industrials at roughly 24–26%, and financials near 10%. The expense ratio is 0.79%, and AUM is comparatively modest, in the range of $125–150 million.

Industry and Thematic Backdrop

Both ETFs are shaped by the same macro and sector forces. Korean equities have been propelled by the AI-driven surge in demand for high-bandwidth memory (HBM), a specialized chip used in advanced AI processors, which benefits Samsung Electronics and SK Hynix directly. Semiconductor export cycles, global data-center spending, and U.S. technology policy are therefore central drivers.

At the same time, Korea's "Corporate Value-up Program" has encouraged companies to improve capital efficiency, buybacks, and dividends, drawing investor attention to financial and industrial names. Risks include currency volatility in the Korean won, geopolitical tension on the Korean peninsula, and the market's dependence on a small number of mega-cap exporters. Sector rotation between semiconductors and value-oriented financial and industrial stocks remains a recurring theme affecting relative performance.

Performance and Positioning Comparison

In recent market cycles, both funds have benefited from the strong semiconductor rally, though EWY's larger combined weighting in Samsung Electronics and SK Hynix has amplified its sensitivity to memory-chip momentum. When AI infrastructure spending accelerated, EWY's concentrated tech exposure tended to move more decisively than MKOR's more balanced positioning. Conversely, MKOR's relative tilt toward industrials and its smaller single-name concentration can provide some cushion when mega-cap tech names correct.

Volatility profiles differ accordingly. EWY's scale and deep liquidity support narrow bid-ask spreads and efficient trading, while MKOR's smaller asset base can translate into wider spreads and less consistent liquidity. From a cost perspective, EWY's 0.59% expense ratio gives it a persistent edge over MKOR's 0.79%, a gap that matters for long-term, buy-and-hold investors. Both remain structurally exposed to the same underlying Korean equity beta, but they express that beta through very different risk and management frameworks.

Refining the View with AI Tools

In my own process, I frequently rely on Tickeron’s AI Screener to quickly filter ETFs and stocks by technical patterns, fundamentals, and AI-driven signals. It helps surface how different vehicles compare on volatility, trend consistency, and sector exposure without spending hours on manual screens. The tool’s customizable filters make it straightforward to isolate candidates that align with a specific thesis like Korea’s semiconductor cycle. I find it especially useful when cross-checking concentration levels or liquidity metrics across similar funds.

Tickeron AI Verdict

Based on observable structural factors, Tickeron's AI would currently favor EWY over MKOR. EWY combines a lower expense ratio, dramatically greater scale and liquidity, and a deeper holdings base, which support efficient execution and long-term cost efficiency. Its heavier concentration in Samsung Electronics and SK Hynix positions it to capture the prevailing semiconductor and AI-memory trend more directly, a factor consistent with stronger recent momentum in technology-led Korean equities. While MKOR offers active management and reduced single-name concentration, its higher cost and smaller footprint make it comparatively less compelling in the current environment. This probabilistic assessment favors EWY on structural strength, cost efficiency, and trend alignment.
