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 79.2% of the fund. The concentration index (HHI) is 804 — Low — evenly diversified, and the largest sector is Unclassified (100%). 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 (804), so no single holding dominates.
Unclassified alone is 100%. This is effectively a bet on that one industry — if the sector falls, diversification will not help.
0.8% a year is on the high side — about 8.0% over a decade, so it needs a reason to earn that.
Net assets of $10M 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.
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 804, with the top 10 holdings at just 79.2% 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, Unclassified alone is 100% — 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
Even its closest peer, NDAA, overlaps only 25% (5 shared names).
Funds filed under the same label can hold quite different companies, so pairing this one with another may genuinely spread risk.
What it is made of
The fund holds 27 positions in total; this page lists the largest 21 and folds the rest into "Others".
The expense ratio is 0.8% a year, which is not cheap. Fees come out of returns every year you hold, so it is worth checking whether the same index is available for less.
