# Performance (by reporting entity)

Daily and accumulated performance metrics for a reporting entity over
a date range. Default is one row per (date, currency) for the entity
as a whole; `expand` breaks the totals down by portfolio, depository,
instrument, or instrument class.

A separate endpoint, /private-markets, returns point-in-time
private-market metrics (NAV, multiples, IRR, cash-flow summary).
