Jeffrey Gundlach, founder of Doubleline, and considered by many to be the “Bond King” has talked about his “hit rate” in various places of being a little over 70%. He talks about this in an interview here.

76% of my calls have been correct in the last year (28 of 37) and 70% of them on my entire website (39 of 56). Since I created my Lantern Daily Economic Index in March of this year, 79% have been correct (23 of 29).

The calls are usually counter to the consensus and often counter to the bond market’s direction at the time. My guiding principle is that interest rates, particularly at the front-end of the yield curve, are driven mostly by trends of aggregate economic data and their interplay with the Fed’s narrative and policy bias. Economic data is understood best on an aggregate basis, the so-called “totality of the data” as the Fed says. I created an index earlier this year to show this, the Lantern Daily Economic Index (LDEI) which gauges economic data growth (real and inflation data) on the day it is released. It is the first of its kind. Back tested to 1998, it helps describe interest rates throughout its history.
