Methodology#
Trailing returns measure from the closest close about N years before the latest close (2026-10-16). Cumulative return is the total change over the window; annualized return is the compound annual growth rate (CAGR), shown for windows of a year or more. Price return is the change in RGEN's closing price; total return reinvests dividends (from its split- and dividend-adjusted closes); the dividends column is the difference between the two. The worst drop is the largest fall in the closing price from a high to a later low inside the window, the way a drawdown is usually quoted. See the year-by-year returns for the calendar breakdown. Past performance does not predict future returns; not investment advice.
