This article includes a speculative grade corporate bond which lets you compute the total realized returns of CCC and below rated corporate debt, as tracked by the Bank of America Merrill Lynch US Corporate Master Index. We are using CPI as our tool inflation measure, and have single day return resolution built into the calculator back to the beginning of 1997.
(Please allow the large dataset to load before closing the window – there is a lot of data behind a daily return calculator.)
Sources and Methodology for the Speculative Grade Corporate Bond Return Calculator
CPI methodology, including interpolation and extrapolation, is available on our original any day inflation calculator. We have inflation data back to 1913, and interpolate (and extrapolate) to give the inflation for any individual day in the last 100+ (and counting) years.
This data is, of course, for research purposes only and should be used as a jumping off point for your investment decisions and own investment research. We believe it to be accurate, but can make no exact claims to the numbers produced.
Even if it is perfectly accurate, your mileage may vary due to tax consequences, slippage, timing, management fees and purchasing costs (among infinite other factors). Even then, it is meant as a representative sample of a large basket of CCC (and below) rated debt, so returns would vary for an individual issue.
Even with those issues in mind, the speculative grade corporate bond calculator should be directionally sound and give an excellent idea of asset class performance in a range once you allow for the errors. If you enjoy it, please give our other calculators a try!
