Key Summary
Rather than a recommendation to buy a specific stock (ticker), the question of how to divide your assets is a variable that, for the individual investor, drives long-term returns even more than stock selection. The 50% US, 30% Korea, 20% remainder framework proposed by Mirae Asset is designed to reduce the KOSPI's semiconductor concentration and diversify across currencies and asset classes, simultaneously drawing attention to adjusting the weighting of Samsung Electronics and SK hynix and to interest in bond-type assets.
What Happened
Park Hee-chan, head of product support at Mirae Asset, mentioned in an interview a composition that sets the baseline for asset allocation at 50% US equities, 30% Korean equities, and the remaining 20% in diversifying assets such as bonds. The key point is to place half the weighting in the US while keeping a separate buffer asset that can absorb volatility when markets are shaken.
What stands out is the rationale for capping the Korea weighting at around 30%. In the KOSPI, the share of market capitalization held by Samsung Electronics and SK hynix — the so-called "Samjeon-nix" — hovers above 50%. Holding the index as is amounts to effectively betting half your money on the two semiconductor stocks (tickers), so Mirae Asset's clients are reportedly observed to be adjusting their Korea weighting to around the 30% level to ease this concentration.
The leading candidate for the remaining 20% was cited as Australian government bonds. The logic is to expect them to play a buffering role by moving in a different direction from equities, given that they are bonds of a country with fiscal soundness and a resource-export base.
Background and Context
Underlying this proposal is the limitation of the KOSPI index's structure. In a structure where the entire index swings on a single cycle of the semiconductor business, passive investors are exposed to a single semiconductor bet regardless of their intentions. Raising the US weighting to half secures exposure to global growth and technology companies while also carrying the character of a currency hedge, diversifying household assets concentrated in won-denominated assets into dollar-denominated assets.
Impact on the Market and Stocks
- Mirae Asset Securities: As a provider supplying ETFs and asset-allocation solutions spanning the US, Korea, and bonds, it sits in a structurally favorable position to benefit — the greater the demand for diversification, the broader its base of management and brokerage revenue.
- Samsung Electronics and SK hynix: The message to lower the KOSPI weighting to 30% may be read in the short term as a burden signal for the two stocks (tickers), but in reality their share prices are tied far more closely to fundamentals — memory prices and HBM demand — than to any diversification recommendation.
- Domestic securities and asset-management sector: The more household assets shift from deposits into globally diversified portfolios, the larger the ETF-fee, wrap, and pension markets grow, so the greater the benefit for providers with a higher weighting in wealth management.
- Dollar and overseas asset classes: The recommendation of 50% US plays a buffering role through foreign-exchange gains during a phase of won weakness, but conversely carries a double edge, as it can come back as foreign-exchange losses when the won turns to strength.
Investor Checkpoints
- If you hold a KOSPI ETF, first check how much the combined weighting of Samsung Electronics and SK hynix accounts for within your Korean equities.
- For Australian government bond products, you need to watch both the path of Australia's benchmark interest rate and the Australian dollar exchange rate against the won. A rate-cutting cycle is favorable for bond prices, but the exchange rate can eat into returns.
- Since the timing effect of expanding US exposure varies with the won-dollar exchange rate level, decide in advance whether to make phased purchases during a period of a sharp gain (surge) in the exchange rate.
- Treat next quarter's memory price trends and US Big Tech earnings releases as the reference events for rebalancing your diversification weightings.
Outlook
Diversification itself is a proven strategy for reducing volatility, and given the KOSPI structure in which half is tied up in a single semiconductor group, the logic of cutting the Korea weighting is persuasive. That said, a composition that raises the US weighting to half is no cure-all, in that it takes on the elevated valuation of the US stock market and the exchange-rate variable as is. If US tech stocks correct or the won turns to strength, the diversification effect may not come through as much as hoped. Ultimately, 50-30-20 is more realistically viewed not as a fixed value but as a starting point to be adjusted to your own currency exposure and risk tolerance.
