We have this ETF's holdings, but the prices for those particular listings are outside our quote coverage (currently Korea- and US-listed securities). So today's contribution and return are not computed — showing 0% would claim it did not move, which is a different statement. The holdings and weights below follow the calculation basis above.
Today's summary
Its top 10 holdings make up about 28.0% of the fund. The concentration index (HHI) is 219 — Low — evenly diversified, and the largest sector is Health Care (87%). The higher the concentration, the more one stock or sector drives the whole ETF's return.
Structural health
A five-axis read on how this fund is built. It is not a return forecast or a recommendation, and a low score does not mean a bad fund — leveraged products score low by design. Each axis shows the figure behind it.
Concentration is below 1,500 (219), so no single holding dominates.
Health Care alone is 87%. This is effectively a bet on that one industry — if the sector falls, diversification will not help.
0.45% a year is typical. Held ten years, roughly 4.5% goes to fees.
Net assets of KRW 208.7B — liquid enough to trade, and unlikely to be wound down.
A plain 1x physical fund holding the shares themselves — no structural drift from how long you hold it.

Where the weight sits — sector mix
Listed equity weights summed by sector and normalized to 100%. Each band is one sector's share.
Industry breakdown
HHI sums the squared weights. The more it leans on a few names, the higher it goes — and the more the whole ETF moves with them.
How concentrated is it
Concentration (HHI) is low at 219, with the top 10 holdings at just 28.0% of equity weight. No single name can dominate the fund.
Good for damping single-stock risk — and equally, a big winner inside gets diluted.
HHI squares each weight and sums them: 10,000 means one stock is everything, and the more evenly spread the holdings, the closer it falls to zero.
Where the sector weight sits
By sector, Health Care alone is 87% — whatever the fund is called, this is a bet on that industry.
Bad news for the sector moves the whole fund. Worth checking against anything else you hold in the same space.
Weights above sum the individually listed equities and normalize that equity total to 100%.
How much it overlaps others
It shares 47% of its holdings with 143860 (42 names in common) — close to half the same companies.
Own both and the diversification is thinner than it looks.
What it is made of
The fund holds 51 positions in total; this page lists the largest 48 and folds the rest into "Others".
The expense ratio is 0.45% a year. Funds tracking the same index tend to perform alike, which makes the fee one of the few things that reliably separates them over time.

Picked by how much their actual holdings overlap. The higher the overlap, the less diversification you get from owning both.
