No dividends recorded.
All calculations use split-adjusted closing prices. Dividends are reinvested on the ex-dividend date at that day's closing price.
For each rolling window, returns are calculated at every possible starting point:
return = (value[i] ÷ value[i − windowSize] − 1) × 100
- Windows
- 1-month = 21 trading days, 1-year = 252 trading days, 3-year = 756 trading days.
- Statistics
- Average: arithmetic mean. Median: middle value when sorted. Best / Worst: max and min. % Positive: share of windows with return > 0.
The series is segmented by calendar year:
return = (endValue ÷ startValue − 1) × 100
startValue is the last value of the prior year (or the first value for the initial year). Partial first/last years are flagged. Dividends, taxes, and transaction costs are scaled proportionally to the initial investment.
