Lesson 5 of 7
Spot APR against the 30-day mean
Why a yield far above its own recent average is more often a spike than a bargain.
Every pool's APR moves. Its 30-day mean is its own recent baseline, so comparing today's APR with it tells you whether you are looking at the pool's normal or at an unusual day.
vs 30d = (APR today − mean APR over 30 days) ÷ mean APR over 30 days
Reading the gap
- Near zero: the pool is behaving as it has been.
- Well above: usually a temporary incentive, a burst of trading, or a drop in capital. These tend to fade, and the capital that arrives to chase them thins the yield further.
- Below: the pool has cooled. Not necessarily bad, but the number you remember is out of date.
How Knowla shows it
The vs 30d column shows the gap in percent. A pool is marked Above recent average when today's APR is more than 1.8 times its 30-day mean (a gap above 80%), and the checklist treats a gap of 80% or more as a watch item. When a pool has no 30-day mean the column shows a dash, and you cannot tell whether its APR is normal.
