Total returns
100% reinvested · ex-date convention. Period returns use this fixed assumption, independent of chart settings. YTD and 1Y are cumulative period returns; 3Y, 5Y, and 10Y are annualized. The shared Since-start window is annualized only when it covers at least one year.
MAIN has outpaced O over the trailing twelve months, posting a -5.32% total return against -5.54%. The lead holds up over 10 years too: MAIN has compounded at 13.09% a year, against 3.28% for O. Figures are total returns: price change plus every distribution reinvested.
| Symbol | YTD cumulative | 1Y cumulative | 3Y annualized | 5Y annualized | 10Y annualized | Since Oct 2007 | Volatility | Sharpe | Sortino | Max drawdown |

Total return with all distributions reinvested on the ex-dividend date (a modeling convention, not the cash-settlement date), split-adjusted, as of October 2, 2026. YTD and 1Y are cumulative period returns; 3Y, 5Y, and 10Y are annualized. The shared Since-start window is annualized only when it covers at least one year. “Since Oct 2007” measures every fund from October 5, 2007 — the start of shared available history — so all funds share one comparison window. Volatility is the annualized standard deviation of daily total returns over the trailing 3 years. Sharpe and Sortino divide the annualized return in excess of the risk-free rate by, respectively, that volatility and the downside deviation (both over the trailing 3 years) — higher is better. Max drawdown is the largest peak-to-trough total-return decline over the same window — shallower is better.
