Update: S&P Dow Jones Indices Launches Additional Daily Proforma Files

Effective Monday, January 23, 2023, S&P Dow Jones Indices (“S&P DJI”) will begin launching additional daily proforma files (DPRO.SDC) for select S&P Indices. As previously announced, the DPRO.SDC is a file that displays rolling index compositions for day T+2 through T+6. Unlike a traditional rebalance proforma file (PRO.SDC) that is sent only during rebalance periods, the DPRO.SDC will be sent daily and reflect any and all upcoming changes due to rebalance or corporate events. Additional details on DPRO.SDC file format and behavior can be found via the original announcement concerning Float Market Cap Weighted (FMC) Indices.

The DPRO.SDC will automatically begin publishing to subscribers' SFTP (EDX) accounts beginning after the close Friday, January 20, 2023.
