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.
  • Financial statements are reported in TWD. Operating margin, ROE and revenue growth are computed within TWD; no figure divides the USD share price by TWD amounts.
