Quote from Vinny1:
These are US government bonds. Very safe investments. The reason I bought these is because long maturity zero coupon bonds are more volatile, which means big moves up and down. Worse case, I hold them until maturity and make back $1,000 per bond, which is 3.5 times my money invested.
Yes, but assuming it is 20 years until maturity, keep in mind this is about a 6.5% annual rate of return (assuming your figure of 3.5 is correct)
After inflation, which we can under-estimate at 4%, you are left with 2.5%.
I don't mean to be a downer but want to make sure you know what you're getting into.
