Year by year
Total return in each calendar year; this year is year to date. A year appears only if SEMI 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.
