Analysis

How it works:

The tool establishes the 1-Month Treasury yield as the baseline (0 years duration).

In evidence-based investing, Larry Swedroe’s "20 basis points" rule of thumb suggests that, for taxable bonds, you should demand an additional 0.20% (20 basis points) in yield for each additional year of duration you take on.

If a longer duration offers a higher premium than required, it becomes the optimal choice. If no durations meet the required premium, the optimal strategy is to stay at the baseline (1 Month) and keep your cash highly liquid.
