In a recent post (see Why this is not the start of a bear market), I raised the question of how a maturing economic cycle might pressure margins. My thesis was mainly based on analysis from Jim Paulsen of Wells Capital Management who believed that operating margins face a lose-lose situation in 2016 (emphasis added):

Earnings performance is well past its best for this recovery and investors need to consider whether earnings growth will prove sufficient to support current stock market valuations. The rapidly aging earnings cycle is perhaps best illustrated by an economy nearing full employment with corporate profit margins near record highs. Should global growth remain tepid and overall sales results modest, since profit margins are unlikely to rise much, earnings trends will also likely prove disappointing. Conversely, should global growth and corporate sales results accelerate, because the U.S. is nearing full employment, companies may soon face cost-push pressures and margin erosion which will likely off set improved sales results.

Essentially, it is difficult to see how earnings growth will be adequate during the rest of this mature recovery to support current price/earnings multiples. Is a relatively modest earnings growth against a backdrop of rising inflation and higher interest rates sufficient to support
