Okay… so you think people should be buying bonds rn? Cant say I agree with the logic you posted being applied that way. Does it matter that your bond is stable if its yielding 5-7% less than your annualized return on index funds? I would say probably not…
you do you. I'm not talking about the timing of anything right now, although bond yields vs equity yields is something that would certainly suggest you should not ignore them. I'm saying mathematically you can have a lower returning investment in your portfolio and it can INCREASE your portfolio rate of return compared to going all in on the higher returning asset that has more volatility. It is not intuitive. It is difficult to wrap your head around. But it is important to understand if you are trying to construct a portfolio that will maximally return value to you over several decades.
I can't call it investing 101, maybe it's a 200 level course. But it's important to understand the math and why it applies to your portfolio. Simply jamming in the things with the highest predicted return is not the way to end up with the most money in the end. So to answer your question....yes it does matter if the bond is stable even if it is returning less than the annualized return on an index fund. The thing with an index fund is we don't know what it will return over the next 10 or 20 or 30 years so trying to pin down what percent more it will be than a bond or bond fund is inexact at best.
