How the accounts work
- Each market has its own account, funded on the first trading day of every month — $1,000 for the US funds, ¥5,000 for the A-shares, never converted
- Buy only, never sell; dividends are reinvested at the ex-date close
- Starts in January 2000. ICBC (listed October 2006) and 515080 (listed November 2019) start on their first trading day; earlier years are left blank
How returns are measured
- Total return: current value ÷ total contributed − 1
- Annualized: money-weighted (XIRR) — every contribution earns only for the time it was actually invested
- Yearly return: Modified Dietz — the year’s gain ÷ (opening value + that year’s contributions weighted by days invested). A DCA account takes in new money every month; comparing year-end to year-start would count contributions as profit
Data
Daily bars and dividends come from Yahoo Finance, using completed sessions only. When the data falls behind the latest close, visiting this page fills the gap in the background.
Limits
- A backtest, not a live account
- No commissions, slippage or taxes
- Fractional shares — the 100-share board lot on A-shares is ignored
- Past performance says nothing about the future
