Methodology#
Weekly returns are total returns (dividends reinvested), computed from XBI's split- and dividend-adjusted weekly (ISO week) closes. The table shows the most recent 260 weeks and the bar chart the most recent 104. See the year-by-year returns for the annual view. Past performance does not predict future returns; not investment advice.
