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 (1,118), so no single holding dominates.
Industrials alone is 71%. This is effectively a bet on that one industry — if the sector falls, diversification will not help.
A plain 1x physical fund holding the shares themselves — no structural drift from how long you hold it.
We don't have cost, fund size for iShares Defense Industrials Active ETF yet, so those axes are excluded and the score is based on the other 3. Scoring a missing figure as zero would grade our data collection, not the fund.

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 1118 — moderate. The top 10 names carry 93.9% 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, Industrials alone is 71% — 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 46% of its holdings with FOWF (9 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 25 positions in total; this page lists the largest 12 and folds the rest into "Others".
Equities are 35.6% of the fund, the rest swaps and cash — index exposure built synthetically rather than by owning the shares, which adds counterparty risk.
