Alternative Data Evaluation overview

Evaluates new alternative data sources for investable alpha signal — assessing data vendor delivery reliability and coverage, profiling data quality (missing values, staleness, survivorship bias), performing point-in-time correctness validation to prevent look-ahead bias, running univariate predictive tests against forward returns, estimating incremental information content versus existing factor library, and analyzing regulatory/compliance implications of data usage. Produces data evaluation scorecards with signal strength metrics, cost-benefit analysis, and integration recommendations. Excludes vendor contract negotiation and data infrastructure provisioning.
