Equity investors around the world had a disappointing year in 2011 as  thirty-seven out of forty-five markets tracked by MSCI posted negative  returns. The US did well on a relative basis and was the only major  market to achieve a positive total return, although the margin of  victory was slim. Total return for the S&P 500 Index was 2.11%, and  the positive result was a function of reinvested dividends—the index  itself finished the year slightly below where it started.   
Throughout the year, investors seeking clues regarding the strength  of business conditions or the prospects for stock prices were confronted  with ample reason to rejoice or despair. Optimists could cite the  strong recovery in corporate profits and dividends, the substantial  levels of cash on corporate balance sheets, low interest rates and  inflation, a booming domestic energy sector, continuing strength in auto  sales, and record-high share prices for leading multinationals such as  Apple, IBM, and McDonald's. Pessimists could point to persistently high  unemployment, slumping home prices, tepid growth in retail sales,  worrisome levels of government debt at home and abroad, and political  gridlock in both Congress and various state legislatures. 
  Although the broad market indices showed little change for the year,  there were opportunities to make a bundle—or lose one. Among the thirty  constituents of the Dow Jones Industrial Average, thirteen had  double-digit total returns, including McDonald's (34.0%), Pfizer  (28.6%), and IBM (27.3%). But losing money was just as easy: The three  worst performers in the Dow were Hewlett-Packard (–37.8%), Alcoa  (–43.0%), and Bank of America (–58.0%). If nothing else, the substantial  spread between these winners and losers discredits the argument we  often hear that all stocks are now marching in lockstep and that  diversification is ineffective.
  Achieving even modest results in the US market required more  discipline than many investors could muster, since investor sentiment  fluctuated dramatically throughout the year and the temptation to  enhance returns through judicious market timing often proved  irresistible.
  For fans of the "January Indicator," the year got off to a promising  start as stock prices jumped higher on the first trading day, pushing  the Dow Jones Industrial Average to a twenty-eight-month high. Bank of  America shares jumped 6.4% that day, the top performer among Dow  constituents. With copper prices setting new records and factory  activity worldwide perking up, the biggest worry for some was the  potential for rising prices and higher interest rates that might choke  off the recovery. "Overheating is the biggest worry," one chief  investment strategist observed. By April 30, the S&P 500 was up  8.4%, reaching a new high for the year. 
  Stocks wobbled through May and June but strengthened again in July.  On July 19, the Dow Jones Industrial Average had its sharpest one-day  increase of the year, jumping over 200 points, paced by strong  performance in technology stocks. Just a few days later, however, stocks  began a precipitous decline that took the S&P 500 down nearly 17%  in just eleven trading sessions. The century-old Dow Theory—a  sentimental favorite among market timers—flashed a "sell" signal on  August 3, and on August 5, Standard & Poor's downgraded US  government debt from AAA to AA+.  As investors sought to assess the  implications of sovereign debt problems in both the US and Europe, stock  prices fluctuated dramatically, with the S&P 500 rising or falling  over 4% on five out of six consecutive trading days in early August.  Rattled by the sharp day-to-day price swings, many investors sought the  relative safety of US Treasury obligations in spite of the rating  downgrade, pushing the yield on ten-year Treasury notes to a record low.  Stock prices hit bottom for the year on October 3 as some market  participants apparently lost all confidence in equity investing. A Wall Street Journal  article cited a number of individual investors as well as professional  advisors who had recently sold all their stocks and did not expect to  repurchase them anytime soon. "I feel like a deer in the headlights,"  said one.
  As it turned out, the article appeared in print on the second day of a  powerful rally that sent the Dow Industrial Average surging over 1,500  points during the next 19 trading days, putting it back into positive  territory for the year. 
  What can we learn from a difficult year like 2011? As Dimensional  founder David Booth is fond of saying, the most important thing about an  investment philosophy is that you have one. Many investors (as well as  some allegedly professional advisors) apparently decided to switch from a  buy-and-hold philosophy to a market timing strategy in the midst of an  unusually stressful period in the financial markets. We suspect few of  those adopting the change would have been able to clearly articulate  their investing beliefs and why they had shifted.  
  Legendary investor Benjamin Graham offered the following observation  nearly forty years ago: "There is no basis either in logic or in  experience for assuming that any typical or average investor can  anticipate market movements more successfully than the general public,  of which he himself is a part."
  Good advice then, good advice now.
