Common questions

How much has MBB returned over the last 10 years?

+8.3% in total, which works out to +0.8% a year over the 10 years to 2026-09-29. 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.

What was MBB's worst year?

2022 — its calendar-year return was -11.7% (net of fees, dividends reinvested). Its best year was 2025 (+8.4%).

How deep was MBB's worst drawdown?

-17.6%, from a peak on 2021-02-09 to a trough on 2023-10-19. From that trough it took 740 days (about 24.3 months) to climb back to the earlier peak.

Does MBB pay dividends?

Over the last 12 months it distributed 4.51% of its share price (as of 2026-09-29). That is a past distribution, not a promise of future income, and it is already counted in every return figure on this page.

What this page does not say

It does not say MBB 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 -17.6% 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.
