Oil & Gas Majors & Pipelines

Integrated majors, producers, refiners and pipelines.

Oil and gas still funds a large share of the world’s dividends and moves with every geopolitical shock. This collection spans the integrated majors, exploration and production, refining, midstream pipelines and the services firms that drill the wells — ranked by market cap.

Why it matters

Integrated majors, producers, refiners and pipelines. These themes often connect to policy, commodity cycles, infrastructure spending and long investment lead times.

What to check next

Check backlog quality, project execution, input costs, balance-sheet resilience and sensitivity to commodity prices or government budgets.

Main risk

Cyclical demand, cost overruns, regulation and commodity volatility can overwhelm even a strong long-term infrastructure or energy story.

It is rebuilt from live market data, so the constituents and their rankings update as prices and company fundamentals change — there is no fixed, hand-edited list.

How should I use the Reward and Risk ratings?

Openbook's Reward rating combines a stock's growth, momentum, profitability and valuation into a single 0–100 score, and the Risk rating scores financial strength, volatility and size. Use them to compare names within this theme — broadly, a higher Reward alongside a lower Risk is more attractive. They are quantitative research signals, not investment advice.
