How this is BUILT

How this roundup is built

This roundup is built only from the committed daily close packs for this period. For each symbol the table shows its single best recorded daily percent gain in the period, with the close price and volume from that same day. Nothing is interpolated: a session with no committed pack has no row here, and months with no packs have no roundup at all.
