Invesco DB Oil Fund is a commodity-focused investment fund that seeks to track the economic performance of crude oil by investing in crude oil futures contracts through a rules-based strategy designed to optimize roll yield—the gains or losses generated when rolling from one futures contract to the next. The Fund targets institutional investors through Authorized Participants and generates returns primarily from futures trading activity, supplemented by income from holdings in Treasury obligations and money market securities used for collateral management. The Fund charges investors a fixed annual management fee calculated on assets under management, along with per-contract trading commissions, and is managed by Invesco Capital Management LLC under CFTC and NFA regulatory oversight.
