Notebooks checking the performance of the MAXIS S&P 500 & All Country ETFs launched in January 2020 against their mutual fund equivalents (eMAXIS Slim S&P 500 & All Country funds).
These calculations are inspired by ones on the Shintaro Money website: S&P 500 & All Country. They account for Japanese taxes on ETF dividends and for the lag between the dividend date and the pay date. The performance assumes you reinvest the dividends on the pay date. The calculations are applicable for ETFs (or mutual funds) held in taxable accounts.
To run the 2559 All Country notebook, ACWI ticker data (Gross & Net) must first be downloaded from MSCI and saved into a TSV file using column headers "Date Gross Net". I could not find an API for this data. If anyone knows of one, please let me know.
