Prologue Industry Indices.
Internally developed decision-support frameworks that track input-cost environments in specialty chemicals, industrial metals and textile raw materials, built from public price references and read two ways: for buyers and for investors.
Current index readings
Indicative readings as of October 2026. Use the tabs or the arrow keys to switch index.
Two reads, one index.
Each index distils a complex cost environment into a level and directional signal, interpreted separately for buyers and investors.
Buyer and sourcing signal
Whether the moment favours locking in prices, buying as you go, or holding course. For buyers, sourcing teams and procurement managers deciding on timing.
Lock in soon · Good time to buy · Hold steady
Investor and margin signal
What the cost environment means for producer margins: whether input costs are building pressure or giving relief. For investors and corporate development teams.
Margin pressure · Margin relief · Neutral
Built on public data, refined by experience.
Grounded in public data
Inputs are drawn from publicly available commodity and chemical price references.
Internally developed
Composition, weighting and signal frameworks are developed by PROLOGUE for strategy, sourcing and investment analysis.
Designed for decisions
A directional read that translates raw price inputs into sourcing and margin signals.
Rules-based
A consistent framework is applied at each update, supporting comparability over time.
The Prologue Industry Indices are internally developed analytical products constructed from publicly available price references. Component prices are indicative and for market-intelligence purposes only; they are not transacted prices and not for trading decisions. Ranges are projections under stable conditions, not guarantees. Signals are interpretive guidance, not investment advice. Indices are updated periodically.
Bespoke cost indices and sourcing intelligence.
PROLOGUE builds bespoke cost indices, sourcing intelligence and decision frameworks for buyers, investors, trade agencies and industry associations.
