In late 2015 and early 2016, as oil crashed, a curious divergence emerged: as crude was dropping, junk bonds crashed with a far greater beta to the drop in the underlying commodity than equities, which remained persistently sticky, stubbornly refusing to drop to a “fair value” implied by oil. The same phenomenon was even more obvious on the way up, as once oil had found a “bottom” energy stocks surged, at times approaching record forward P/E multiples.
