What is the PVCI?
The PVCI measures the performance of public stocks, tracking VC-backed companies beginning at the time when they go public.
Companies remain in the index for 10 years from the IPO launch date or until price data is no longer available, they are acquired or 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.
