03 · Prism readout

What the signals say—and what they do not

The headline share is normalized petroleum refining news attention across these five names. Partial community coverage and U.S.-scope patent records are displayed separately and are not blended into it.

Scale + attention

Chevron leads the conversation

It holds 53.6% of measured petroleum refining news attention and also carries the basket's largest revenue base at $184.43B.

Price path

Marathon Petroleum leads the available price paths

Its monthly-close return is +513.4% for the five-year window. At the other end, Chevron is +106.4% for its five-year window. Windows printed on each card must be compared carefully; price history is not a forecast.

Profitability

ExxonMobil has the widest latest margin

Its FY2021 net margin is 8.3%. Its revenue history in this snapshot spans only the periods printed on its card, so longer histories are not treated as equivalent.

Price vs operating signals

Marathon Petroleum shows why one ratio is not a verdict

It has the basket's lowest snapshot P/E at 12.8x while its five-year window price return is +513.4%. Valuation, price path and readiness answer different questions.

Explanations

Attention measures coverage volume, not quality

Chevron's 53.6% share says it appears most often in the matched Prism corpus. It does not score whether that coverage is favourable or whether the company is investable.

Different windows explain why signals can disagree

Revenue comes from the printed filing periods, price paths use the dated monthly-close windows, and Prism signals use their stated event windows. No causal attribution is made across them.
