Here we go again, creating another asset bubble for the third time in a decade and a half, is how Monument Securities' Paul Mylchreest begins his latest must-read Thunder Road report. As Eckhard Tolle once wrote, “the primary cause of unhappiness is never the situation but your thoughts about it," and that seems apt right now. After Lehman, policy makers went “all-in” on bailouts/ZIRP/QE etc. This avoided an “all-out” collapse and bought time in which a self-sustaining recovery could materialize. The Fed’s tapering threat showed that, five years on from Lehman, the recovery was still not self-sustaining. Mylchreest's study of long-wave (Kondratieff) cycles, however, leaves us concerned as to whether it ever will be. More commentators are having doubts; and the problem looming into view is that we might need a new "plan." The (rhetorical) question then is "Have we really got to the point where it's just about more and more QE, corralling more and more flow into the equity market until it becomes (unsustainably) 'top-heavy'?"
