• Bloomberg Open Symbology Project – Open ended project to create and evaluate possible methods to update current RIMES securities database with Bloomberg tickers. ---- Familiarized and worked with MIC exchange codes, SEDOL, ISIN, CUSIP security identifier structure; understanding permissioning problems with CUSIP identifier.---- Conducted quantitative review and evaluated effectiveness on a per method basis. Evaluated entire rimes database coverage and discovered effectiveness of using SEDOL as identifier: Above 80% coverage on Bonds, Fixed Income and other similar ABSs. Below 35% coverage for equities because issue of multiple exchanges. ---- Created multiple methods to obtain higher accuracy for equities: filtering on country and utilizing primary exchange MIC code. Method created showed above 90% coverage.---- Created full database mapping from primary MIC to Bloomberg tickers: Bloomberg Tickers are now fully integrated into current RIMES database based on created mapping.• Index data rollup project – Creating proprietary data checks to assess integrity of index data from data providers.---- Acquainted with how index levels are calculated: total return, gross return; how weights of indices are calculated and rebalanced. ---- Created rolled up checks to verify top levels of indices (calculating index levels using constituent data).---- Corrected miscalculated index data by manually recalculating weights and projecting index top level.
