Validation universe relevance

The headline validation result was measured on a curated 336-symbol Yahoo validation universe selected for financially relevant, liquid, high-attention market coverage.

That universe is intentionally enriched for financially important, liquid, high-attention market symbols, including major ETFs, index proxies, mega-cap technology, semiconductor names, and other widely followed U.S. equities. Examples from the validation universe include SPY, QQQ, VTI, VOO, IVV, DIA, IWM, AAPL, MSFT, AMZN, GOOGL, NVDA, AMD, AVGO, QCOM, TXN, TSLA, and other high-importance market names.

This matters for interpretation: the 336-symbol result is commercially meaningful because the selected symbols are closer to the liquid instruments that many quant, brokerage, and portfolio workflows care about.
