# DAT Companies by Asset

> Holdings of a digital asset treasury company in one crypto asset: units held, their USD value and units bought that day. Each series is one company and asset pair, keyed by ticker and asset symbol.

One row per company and crypto asset held in a digital asset treasury, keyed by ticker and asset symbol: company ticker, asset symbol and the asset's native chain. The id is the series key of the dat-companies-by-asset timeseries model.
