Oil is it a buy or sell

The deep research logic is organized as follows: 

Okay, let's tackle this question: "Oil is it a buy or sell." The user wants to know whether to buy or sell oil-related investments. First, I need to look through the provided references and background to gather relevant data.

Starting with the latest oil prices, reference 20 shows Brent crude at $64.86 per barrel on June 5, 2025. That's a key point. Then, looking at the ETF and stock prices, reference 11 mentions the USO ETF at $69.34 with a slight drop of 0.79%. The oil stocks listed in reference 12 all have negative changes, ranging from -1.41% to -3.41%. This suggests recent downward pressure on oil-related assets.

The geopolitical factors are crucial. References 1, 3, 15, 16, 17, 22, 25, 26, 27, 28, 29, and 30 discuss trade wars, sanctions, and production increases. For example, OPEC+ is increasing production, which could lead to oversupply. The US-China trade deal in May 2025 (references 28 and 29) temporarily reduced tariffs, boosting oil prices, but the long-term impact is uncertain. Also, the IEA report (reference 15) mentions a record $3.3 trillion in energy investment, mostly in clean energy, which might shift focus away from oil.

Market sentiment is mixed. Recent price drops (references 6,
