I think you should read https://personal.vanguard.com/pdf/ICRIBI.pdf

You generally seem to be conflating face (static) value with market (dynamic) value. You're not wrong but your article makes a number of statements implying a ladder is better/safer simply because you refuse to recognize that the current value will deviate from par.

Cool. I will read that. I'm trying to address the practical case of buying something, earning interest, then selling it and/or having it mature, not holding into perpetuity. Maybe I can be more clear about this in the post so after I read this I can make an update. Thanks for linking!

I added: Some readers have pointed out that over the long term there isn't a difference between building a ladder and using a similar bond fund. This strategy assumes that eventually you'll want to move your principle out of bonds and into something else like a down payment (while rates are still rising), but you don't have a well-defined timeline. If you are planning on keeping your principle invested in bonds into perpetuity then a bond fund might be a more suitable investment.

Thoughts?
