Pluris Valuation Advisors collects data on trading activity in the secondary markets for illiquid securities. This data, included in our LiquiStat database, is completely unique and proprietary to Pluris. However, we often provide an analysis of market evidence for publication in articles, white papers, etc. Our white paper titled “The Secondary Market For Auction Rate Securities” provides you with ARS trading data on auction rate securities that has never been published prior to now.
