The second-by-second levels data availability of the indexes vary depending on when they were released to the public and consumed by IDC’s basket calculator.

Sector Indexes

  • Sector indexes were based at 1000 on a date in the series that is earlier than the date that we are starting the indexes in these files. The September 21 start date is used because it is as of this date that the current constraint methodology was finalized.

  • Total return index levels, while indexed to 1000 on the start of February 2, 2012, begin in the data files on December 7, 2012.
  • Exception: CRSP REIT price and total return indexes are indexed to 1000 on the start of April 1, 2011. This is because they were released with the Total Market and Capitalization Indexes.
