Its top 10 holdings make up about 40.8% of the fund. The concentration index (HHI) is 400 — Low — evenly diversified, and the largest sector is Energy (40%). 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 (400), so no single holding dominates.
Energy is 40%, a clear tilt. That industry's swings will drive the fund.
0.62% a year is on the high side — about 6.2% over a decade, so it needs a reason to earn that.
Net assets of $1.3B — 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 400, with the top 10 holdings at just 40.8% 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 Energy(40%) · Consumer Discretionary(20%) · Health Care(16%). At 40%, 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
Even its closest peer, FNK, overlaps only 32% (15 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 454 positions in total; this page lists the largest 25 and folds the rest into "Others".
Equities are 10.3% 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 0.62% 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.
