Key Takeaways
A momentum-style ETF that screens for and holds only winning stocks dropped Tesla and concentrated on large-cap semiconductor names such as Samsung Electronics and SK hynix, gaining roughly 64% this year. Because it is a concentration-driven product that dilutes an ETF's original character as a diversified investment, both the source of returns and the risks have grown at the same time. For investors, it matters not just to look at the headline return, but to understand what drove this performance — and how sharply losses could be amplified if that momentum reverses.
What Happened
The ETF drawing attention tracks an underlying index but overweights stocks with strong price momentum while screening out laggards. Names whose profitability or share-price trends have weakened are dropped from inclusion — and it is symbolic that Tesla, once an emblem of growth stocks, was pushed out of the weighting on the grounds that it was no longer making money. Conversely, Samsung Electronics and SK hynix, whose earnings and share prices have improved together on artificial intelligence (AI) demand, rose to become core holdings.
With leverage layered on top, the fund delivered performance more than three times that of the underlying index. In other words, the 64% return is the combined result of a stock-selection effect and a leverage-amplification effect, and cannot be explained by the pure rise in the underlying stocks alone.
Background and Context
As the memory semiconductor industry recovered this year, led by high-bandwidth memory (HBM) for AI servers, the earnings momentum of SK hynix and Samsung Electronics strengthened. Because a momentum strategy is structured to chase stocks that have already risen, it is strong in the early-to-middle stages of a bull market but also carries the weakness of being the last to exit at inflection points where the trend breaks.
Impact on the Market and Stocks
- Samsung Electronics: As a core holding of the momentum ETF, it is a direct beneficiary of fund inflows as long as expectations for HBM and foundry hold up. That said, it is sensitive to foreign investor order flow and the exchange rate.
- SK hynix: With its lead in HBM, it is the stock with the greatest earnings leverage. Positioned among the ETF's top weights, its share-price volatility drives the ETF's performance.
- Semiconductor materials, parts and equipment: If memory capital spending expands, warmth could spread to back-end and equipment names such as Hanmi Semiconductor, but volatility is higher than for large caps.
- Tesla: As a case of being dropped on momentum criteria, it shows that growth stocks with weakening profitability and share-price trends can face fund outflows from these strategy-driven products.
Investor Checkpoints
- Leveraged ETFs track daily returns, so compounding losses (volatility drag) occur in sideways markets. Investors should first check whether they view their holding period as short or long.
- Confirm whether the momentum can be sustained through SK hynix's and Samsung Electronics's next-quarter earnings, HBM supply-contract disclosures, and trends in DRAM fixed transaction prices.
- Investors should check the concentration of holdings (the weight of the top 2–3 names) and the rebalancing cycle directly in the ETF's composition to assess how much diversification benefit actually remains.
- The won-dollar exchange rate and foreign net buying flows should be monitored as leading indicators of order flow for large-cap semiconductor stocks.
Outlook
If the AI investment cycle continues and memory prices keep rising, improving earnings at the large-cap holdings could underpin the ETF's performance. However, since a substantial part of the 64% return came from leverage and concentration, any debate over a peak in the semiconductor cycle or a wave of profit-taking would amplify the downside by the same multiple. As a product whose diversification — the ETF's safety net — has been weakened, investors need to understand the high return as the result of layering leverage on top of a sector bet, and to approach it only within a range of volatility they can tolerate.
