Dividend History

Date Per Share Yield %
Total 0 payments
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.
