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 63.0% of the fund. The concentration index (HHI) is 1326 — Low — evenly diversified, and the largest sector is Information Technology (60%). 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 (1,326), so no single holding dominates.
Information Technology alone is 60%. This is effectively a bet on that one industry — if the sector falls, diversification will not help.
At 0.02% a year this is a low-cost fund — little drag over a long hold.
Net assets of KRW 39.2B are small. Thin funds trade at wider spreads, and very small ones get closed or merged.
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) sits at 1326 — moderate. The top 10 names carry 63.0% of equity weight, so the fund is spread out but its largest holdings still steer it.
That is the usual shape of a cap-weighted index fund: broad, yet tilted toward the biggest companies.
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, Information Technology alone is 60% — 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
Its closest neighbour is 227830 at 96% overlap — effectively the same basket.
Holding both is not diversification, it is buying the same companies twice. Pick whichever is cheaper.
What it is made of
The fund holds 735 positions in total; this page lists the largest 309 and folds the rest into "Others".
The expense ratio is 0.02% 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.
