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.

71/ 100
BSound structure
DiversificationHHI 244100

Concentration is below 1,500 (244), so no single holding dominates.

Sector balanceEnergy 96%0

Energy alone is 96%. This is effectively a bet on that one industry — if the sector falls, diversification will not help.

Structural simplicityPhysical, 1x100

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 State Street SPDR S&P Oil & Gas Exploration & Production 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.

Concentration at a glanceHHI 244well spread

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 244, with the top 10 holdings at just 28.7% 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

By sector, Energy alone is 96% — 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 61% of its holdings with PXE (24 names in common) — close to half the same companies.

Own both and the diversification is thinner than it looks.
