Index Maintenance

PHOTON Consulting has developed survey criteria and methodologies that will ensure consistent price reporting. PHOTON Consulting also continues to refine the indexing and survey methodology to improve on the accuracy of the Index. On occasion, new survey participants may be added to the PCSPI and will be reflected in the PCSPI results as it is updated and published each month.

Index Calculation & Weighting

The PHOTON Consulting Silicon Price Index (PCSPI) is a weighted index in which silicon prices reported by each survey participant are weighted to reflect the nuances found in the length of reported silicon contracts, prepayments and price digression.

Index Universe (Participants)

The PCSPI relies on data gathered from survey participants with exposure to silicon contract and spot prices. The current organizational composition of the index includes both privately held and publicly traded buyer (consumers), seller (producers) and trader companies located in North America, Asia, and Europe.
