These figures pool every individual call made by William Blair's analysts into a single sample — so a prolific analyst carries more weight than a low-volume one, exactly in proportion to the evidence available. All metrics are computed independently by 13Foresight from historical prices. Returns are measured in each stock's own trading currency, so for non-US listings the comparison against the S&P 500 does not account for currency moves — a US investor's dollar return would differ by however the exchange rate shifted.
