Aims for twice the daily return of an index of Nasdaq-listed biotechnology and drug companies, using swaps. Because it resets daily, its return over longer periods can differ a lot from twice the index.

Year by year
Total return in each calendar year; this year is year to date. A year appears only if BIB traded for all of it.
Total return on the market price, with each distribution reinvested on its ex-date. Not the NAV return the issuer publishes; the two differ when the ETF trades above or below the value of its holdings. The narrative is the asset-weighted return of the unlevered ETFs that carry it. The market is the asset-weighted return of broad US index ETFs. Past performance is no guarantee of future results.
