The Mistake Eveyone Is Making About Fed Rate Hikes

With the Federal Reserve now indicating that they are "really serious" about raising interest rates, there have come numerous articles and analysis discussing the impact on asset prices. The general thesis is based on averages of historical tendencies as discussed recently by David Rosenberg in his daily commentary :

"Equity bull markets never die simply of old age. They die of excessive Fed monetary restraint - but the Fed hasn't even started to raise rates yet.

In the past six decades, the average length of time from the first tightening to the end of the business cycle is 44 months; the median is 35 months; and the lag from the initial rate hike to the end of the bull equity market is 38 months for the average, 40 months for the media."

So, why fear a Fed rate hike at this point? According to Rosenberg, there are still at least three years left to the current business cycle. Right? Maybe not.

First, averages and medians are great for general analysis but obfuscate the variables of individual cycles. To be sure, the last three business cycles (80's, 90's and 2000) were extremely long and supported by a massive shift in financial engineering and credit leveraging cycle. The post-Depression recovery and WWII drove the long economic expansion in the 40s, and the "space race" supported the 60s.
