Has unchecked optimism inflated asset values?
“Irrational exuberance.” That phrase – uttered by Federal Reserve Chairman Alan Greenspan in 1996 and reputedly coined by economist Robert Shiller – has become part of the investment lexicon. Now and then, bears reference it – especially when the market turns red-hot.

As 2014 ends, the broad benchmark is poised for another double-digit annual gain. Asked to explain the difference, bearish market analysts might point to irrational exuberance.1
