+309.77% in total, which works out to +15.15% a year over the 10 years to 2026-10-02. Both figures assume dividends were reinvested and the fund's own fees were already deducted, so they are what an investor would have kept — before tax.
2022 — its calendar-year return was -18.27% (net of fees, dividends reinvested). Its best year was 2019 (+30.93%).
-33.83%, from a peak on 2020-02-19 to a trough on 2020-03-23. From that trough it took 142 days (about 4.7 months) to climb back to the earlier peak.
Over the last 12 months it distributed 15.08% of its share price (as of 2026-10-02). That is a past distribution, not a promise of future income, and it is already counted in every return figure on this page.
It does not say BTIIX is a good or bad fund, and it is not a forecast. Returns above are history: they already include dividends and already exclude the fund's own fees. A drawdown of -33.83% means an investor who bought at the peak would have watched that much value disappear before it recovered — how long that takes is the part most tables leave out.
