The Thomson Financial Post-Venture Capital Index (PVCI) is a market-valued index that measures the performance of public companies that have received financing from a U.S. venture capital firm or buyouts limited partnership prior to going public. The index, which at present comprises 644 companies, seeks to track the universe of venture-backed stocks from the point of going public until publicly traded for 10 years. Companies are taken off the index after 10 years or if they are acquired, merged to form a new corporate entity, or are removed from a publicly traded exchange. The index is calculated daily and does not take into account dividends. It began in January 1986 with an initialized index value of 100.

As of Sept. 29, the index value of the PVCI was 637.8, up from 608.04 a month earlier. Separately, the PVCI had a market capitalization of $637.81 billion on Sept. 29, up from $599.4 billion on Aug. 31. —Lawrence Aragon
