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 34.7% of the fund. The concentration index (HHI) is 202 — Low — evenly diversified, and the largest sector is Information Technology (45%). 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 (202), so no single holding dominates.
Information Technology is 45%, a clear tilt. That industry's swings will drive the fund.
0.64% a year is on the high side — about 6.4% over a decade, so it needs a reason to earn that.
Net assets of KRW 134.9B — liquid enough to trade, and unlikely to be wound down.
An inverse fund. It rises when the index falls, but daily resetting means it does not mirror the index exactly over long holds.

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.
Leverage / inverse caveat
This fund tracks 1x the inverse of its index — it rises when the index falls, and vice versa.
That 1x applies to a **single day**. Held longer, the daily reset makes the period return drift from 1x the index: if the index chops up and down and returns to where it started, this fund is still down. That is volatility decay.
It bites hardest in sideways markets and compounds with holding time. These are built for short directional trades.
How concentrated is it
Concentration (HHI) is low at 202, with the top 10 holdings at just 34.7% 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
Sector weights run Information Technology(45%) · Health Care(27%) · Industrials(9%). At 45%, the leading sector is a clear tilt.
Expect it to ride that industry's cycle — ahead of the index in good stretches, behind in bad ones.
Weights above sum the individually listed equities and normalize that equity total to 100%.
How much it overlaps others
It shares 56% of its holdings with 233740 (3 names in common) — close to half the same companies.
Own both and the diversification is thinner than it looks.
What it is made of
Equities are -100.0% of the fund, the rest swaps and cash — index exposure built synthetically rather than by owning the shares, which adds counterparty risk.
The expense ratio is 0.64% 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.

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