David is designed to mirror the breadth of a real market-data vendor while remaining fully synthetic.

​
Universe size

David covers 16,143 real public US symbols, sourced from SEC and Nasdaq listings, and every scenario can address the full set.
Company facts, prices, fundamentals, filings, news, events, and ownership are generated deterministically from the scenario and ticker, giving broad real-symbol coverage across the universe.

​
Horizons

Scenarios deliberately mix time horizons rather than forcing one length:
HorizonTypical span
Full panel~30 years
Business-cycle panelseveral years
Annual event study~1 year
Focused event windowweeks to months
A scenario’s actual span is given by its start_date and end_date. Trading days are synthetic calendar days. See Date semantics.

​
Coverage map

David implements a Financial Datasets–style endpoint surface, native endpoints plus derived compatibility views (as-reported statements, segments, screeners, KPI/non-GAAP metrics, index funds, interest rates, market snapshots). The live coverage map is available at GET /metadata/financial-datasets-coverage.
