The Globe and Mail reports in its Saturday edition that Investing.com publishes the daily closing value of the S&P/TSX Capped Composite Total Return Index, which can be found by entering the full index name into the search box or using the symbol TRSPTSECP3. The Globe's John Heinzl writes that a total return index assumes that all dividends were reinvested, unlike the regular S&P/TSX index, which reflects price changes only and excludes dividends. The Globe columnist says that to calculate the change in the total return index for 2023, click on "historical data" and expand the date range to look up the index's closing values for 2022 (87,332.43) and 2023 (97,594.53). The difference between these two numbers is 10,262.10, which works out to an increase of 11.8 per cent. That was the S&P/TSX's total return last year, compared with a gain of 8.1 per cent for the index without dividends. He adds that you can use this method to calculate the index's total return for any time period If you want to find total returns for individual Canadian stocks, check out the compound returns calculator at CanadaStockChannel.com.
