PVC index –

The Thomson Venture Economics Post-Venture Capital Index (PVCI) is a market-valued index that measures the performance of public stocks of companies that have received venture capital or buyout financing. The index, which at present comprises 667 companies, seeks to track the universe of venture-backed stocks from the point of going public until publicly traded for 10 years, at which time they are removed from the index. 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 Aug. 31, its market capitalization was $660.9 billion, down from $672.5 billion on July 31.
The PVCI defines “venture-backed” companies as public companies that have received financing from a U.S. venture capital firm or buyouts limited partnership prior to going public. Companies remain in the index for 10 years from the IPO date or until price data is no longer available. Companies are taken off the index if they are acquired, merged to form a new corporate entity or are removed from a publicly traded exchange.
