At the tail end of 2014, individual investors as well as financial web site editors asked me for predictions on a variety of assets heading into 2015. I answered as many folks as I could. I suggested that foreign developed stocks via iShares Currency Hedged EAFE (HEFA) or Vanguard Europe Pacific (VEA) would likely outperform U.S. stocks, due to perceived value, easing of monetary policy and four consecutive years of foreign equity underperformance. (When was the last time that U.S. equities outperformed foreign equities for a fifth consecutive year? I am going to guess, “Never.”)

Indeed, funds like HEFA and VEA have outperformed the S&P 500 year-to-date. However, most of the gains came in the first quarter. Since the beginning of April, the relative strength on foreign stocks has been eroding on euro-zone uncertainty and economic deceleration in Asia.

I also advocated on behalf of the largest of the large-cap companies over small-cap corporations. I anticipated that favorites like iShares S&P 100 (OEF) and Vanguard Mega-Cap Growth (MGK) would fare better than the Russell 2000 based on relative valuation, macro-economic weakness and latter-stage bull market allocation shifts. Historically, small caps tend to dominate early in bullish uptrends, yet fade toward the back end of a cycle.

Admittedly, small-caps had been surprisingly strong out of the 2015 gate. It wasn't until the last 30 days – a period typified by the possibility of a Greek tragedy as well as U.S. economic downgrades – that smaller companies began to drift lower.

In truth, calendar-year predictions do no mean very much. I often explain to “do-it-yourselfers” that they should pay more attention to the management of downside risk than the pursuit of upside outperformance.

Minding the store for the possibility of loss becomes particularly important when bull markets become “long in the tooth.” The current run represents the third longest in history and the other two did not make it past eight years. That said, the problem is not participating in latter-stage bull markets with extreme overvaluation and/or exaggerated exuberance. The issue is whether or not a do-it-yourself individual understands how to take action to avoid the bulk of eventual adversity.
