Berkshire Hathaway (BRK.B, total return)benchmark · total return (same basis)25%55%75%
S&P 500 (price return)benchmark · price return12%25%84%

Two benchmarks, and we’re careful about the basis. Company returns are total returns (dividends reinvested). Berkshire Hathaway (BRK.B, total return) is on the same total-return basis — the fair, like-for-like comparison (Berkshire pays no dividend, so its dividend-adjusted and price series coincide). The S&P 500 (price return) is a price index that excludes dividends and so understates the market by roughly its dividend yield — shown for reference, not as a fair bar. A “—” is an unfinished forward window or a name without joined returns, never a zero. Where a name stopped trading mid-window it reports null with a note, never a guessed return.

The caveats, in the engine’s own words

  • Point-in-time reconstruction: each score uses only SEC filings on file by Dec 31 of the cohort year; restatements filed later are ignored, and filers with December fiscal year-ends are scored off the prior fiscal year (their 10-K arrives the following spring).
  • Survivorship bias: unless delisted companies were ingested explicitly by CIK, the cohort is drawn from companies still filing with the SEC today — names that failed or delisted since are missing, which flatters any forward-looking comparison. Companies whose filings had already gone stale at the cutoff are computed but excluded from the ranking (the stale count). The same caveat extends to returns: a name that stopped trading mid-window reports null with a note, never a guessed return through its delisting. Price histories are keyed by each company's ticker symbol as of today; a symbol that changed hands between issuers during a window can misattribute price history.
  • Scores are business-quality only: no prices feed them, so valuation, margin of safety, and price-dependent verdicts are absent. Forward returns are a separate join of market data made after scoring and never influence any score.
  • Forward returns start strictly after the information cutoff: entry is the first trading close on or after Jan 1 of the year following the cohort year, and each 1y/3y/5y window runs anchor-to-anchor to the first trading close of the corresponding later year. Windows that have not fully elapsed are null — never annualized or extrapolated from a partial period.
  • Return basis honesty: company returns are total returns (split-adjusted closes with dividends reinvested at the ex-date); the S&P 500 benchmark is the ^GSPC price index, which excludes dividends and therefore understates the index by roughly its dividend yield in any comparison. A second benchmark, Berkshire Hathaway (BRK.B), is computed on the SAME total-return basis as the companies — Berkshire pays no dividend, so its dividend-adjusted series equals its price series, and the same code path is used so the comparison is strictly like-for-like. Each record labels its own returnBasis.
  • Educational, not investment advice. Hindsight makes every backtest look wiser than anyone could have been at the time.
