Method and limits

  • Returns use us_price:adj_close, adjusted for splits and dividends where available.
  • Excess returns use world_index:^GSPC as the S&P 500 benchmark proxy.
  • Quarterly fundamentals are aligned to SEC filing dates before daily valuation studies.
  • The promoted universe starts from active NYSE/NASDAQ common stocks, then applies price and dollar-volume gates.
  • Snapshot-only tables such as analyst consensus, DCF, us_ratios, and us_key_metrics are intentionally excluded from historical evidence.
  • Overlapping event windows are descriptive distributions, not independent samples.
  • This is an American depositary receipt (ADR). The data does not say how many ordinary shares each ADR represents, so per-share and market-value metrics (P/E, price/book, free-cash-flow yield, EPS growth and earnings surprises) are not computed.
  • ADRs listed on NYSE or NASDAQ are covered as a separate group selected by dollar volume, in addition to the common-stock universe; the 6-month momentum signal ranks each ADR against the liquid US common stocks.

This page is for historical data analysis and education only. It is not investment advice. Backtests and historical return distributions do not predict future performance; evaluate risk independently before trading.
