In Exhibit 21, we compare the five-year annualized expected total returns published in our 2013 Outlook to what transpired over the last four years. Our forecasts for 1) fixed income returns including both investment grade and high yield, 2) hedge fund returns, and 3) EAFE equity returns were close to the mark. Directionally, we were also right about US equity returns but off in terms of magnitude. We were also struck by how close our US bank sector return forecasts were to the realized returns—approximately a quarter of which were realized after the November election.

Not surprisingly, we have not been right across the board. We underestimated Japanese equity returns by 11.4 percentage points on an annualized basis and we overestimated emerging market equity and emerging market local debt returns, by sizable 13.5 and 12.1 percentage points, respectively, on an annualized basis. Japanese equities realized an annualized 18% return and EM equity and local debt realized negative returns, at -2% and -5% annualized, respectively. While our forecasts were off the mark, our emerging market investment recommendations were on the mark. In mid-2013, we recommended clients reduce their strategic allocation to emerging market assets.
