Date

Entries in the Date column must conform to the relevant date format string in the project’s configuration file (see Setting up the configuration file).

Data may be supplied at any frequency you wish, including daily, weekly or monthly. We recommend daily data for most accurate results. If a few days are missing, FIA will use the most recent data available up to that point for attribution.

Each portfolio file must have data from at least two dates. The first can be a single line with zero holdings.

If you are using a benchmark file, it must have data at the same dates as in the portfolio file.
