This is a screenshot from the top-level bond table on etrade.com, and I am having a hard time understanding it. I understand how bonds work, and what maturity/coupon/yield/etc are, but I'm not sure how to read the numbers here, because they don't make sense as percentages or as multipliers.
For instance, take the category CDs for 1Y-- the top-left cell. It can't be that the yield is 1.46x initial investment, that wouldn't make sense or nobody would really buy anything else. But it also can't be 1.46%, because that would imply that a 30Y US Treasury bond only yields 2.78%, which is nonsensically low.
I know I'm getting something wrong here, but I don't know what it is. What do these numbers mean?
