The lecture is not boring and fun. It explains backtesting and visualization of asset allocation, and it is easy to understand because it is explained very well. These days, many people are saving pensions and doing personal IRP, so it would be good to try backtesting and invest directly. Since many good domestic ETFs have been released recently, I calculated the CAGR and MDD by applying the exchange rate to the corresponding overseas ETF and determined the investment ratio.
