Individual Investing

How and why do individual U.S. investors diversify internationally? How significantly does this diversification affect their portfolio results? In their April 2007 paper entitled “Foreign Investments of U.S. Individual Investors: Causes and Consequences”, Warren Bailey, Alok Kumar and David Ng analyze the motivations and consequences of foreign equity investment by individual U.S. investors. Using personal characteristics and portfolio/trading data from tens of thousands of individual brokerage accounts at a major U.S. discount broker for the period 1/91-12/96, they conclude that: Keep Reading

Is individual investing an inevitable series of randomly spaced ups and downs, or do some investors persistently enjoy more success than others? In their August 2007 paper entitled “Performance Persistence of Individual Investors”, Limei Che, Øyvind Norli and Richard Priestley investigate performance persistence among individual stock market investors/traders. Using monthly stock portfolio data for all individual investors who traded at least six times every 24 months on the Oslo Stock Exchange during January 1993 through June 2003 (65,848 investors), they find that: Keep Reading

Do individuals understand their actual aggregate investing/trading performance? In their July 2007 paper entitled “Why Inexperienced Investors Do Not Learn: They Don’t Know Their Past Portfolio Performance”, Markus Glaser and Martin Weber measure whether individual investors can correctly estimate personal absolute and relative stock portfolio performance. Using the responses of 215 online investors to a 2001 internet survey and actual portfolio returns for these investors during 1997-2000 as calculated from their holdings during that period, they find that: Keep Reading

Readers recently requested evaluations of two different retail investment managers. Our reviews involve simply putting the information the firms make available on their web sites into the context of broad stock market research. Our findings for the two firms are similar, as follows: Keep Reading

What is the recent evidence on the performance of individual investors? Do some persistently outperform and, if so, why? In the February 2007 draft of their paper entitled “The Performance and Persistence of Individual Investors: Rational Agents or Tulip Maniacs?”, Rob Bauer, Mathijs Cosemans and Piet Eichholtz examine the performance and persistence of individual investors trading at a Dutch online broker. Using a database consisting of more than 68,000 accounts and eight million trades in stocks, bonds and derivatives during January 2000 to March 2006, they find that: Keep Reading

Is more investment information always better? Are there unintended consequences for individual investors/traders acquiring investment information? Specifically, do individual investors/traders systematically acquire information to support rational future decision-making, or do they focus on information that confirms (and builds overconfidence in) decisions already made? The following two recent studies examine these questions, with results as follows: Keep Reading

How do typical investors/traders process advice from others? Are they overconfidently dismissive, or underconfidently trading on the latest guru pronouncement? In their February 2006 paper entitled “Effects of Task Difficulty on Use of Advice”, Francesca Gino and Don Moore perform two controlled experiments to examine the tendencies of people to reject or accept advice depending on the complexity of the associated task. In one experiment, the 61 participants (mostly university students) must seek advice, and in the other they have the option of seeking advice. Since the advice came from other participants who were generally no better informed, the best strategy for each participant was to reduce noise by averaging own opinion and advisor’s opinion. Based on the results of these experiments, the authors conclude that: Keep Reading

Is success as an entrepreneur all luck, or is there a provable contribution from skill? Do winners win just because they are willing to roll the dice, or because they consistently bring innovative insights to the market? In their July 2006 paper entitled “Skill vs. Luck in Entrepreneurship and Venture Capital: Evidence from Serial Entrepreneurs”, Paul Gompers, Anna Kovner, Josh Lerner and David Scharfstein pit skill against luck by investigating the persistence of success among serial entrepreneurs. Focusing on the founders of companies listed by Venture Source as recipients of venture capital during the period 1975-2000, they conclude that: Keep Reading

Do mutual fund investors move their money into and out of the stock market at the right times, or the wrong times? In their August 2006 paper entitled “Mutual Fund Flows and Investor Returns: An Empirical Examination of Fund Investor Timing Ability”, Geoffrey Friesen and Travis Sapp examine the flows of funds to/from individual mutual funds to measure the timing ability of fund investors. They define a “performance gap” between the time-weighted (buy-and-hold) return and the dollar-weighted (actual investor average) return as the measure of investor timing ability. Using monthly data for 7,125 mutual funds over the period 1991-2004, they find that: Keep Reading

Do sophisticated (wealthy) investors chase hedge fund returns? If so, should they? In their March 2006 paper entitled “Do Sophisticated Investors Believe in the Law of Small Numbers?”, Guillermo Baquero and Marno Verbeek investigate whether sophisticated hedge fund investors exhibit “hot hands” bias by overreacting to small samples of fund performance. They hypothesize that investors who believe that hedge fund performance is predominantly skill (luck) are prone to overestimate the likelihood of performance persistence (mean reversion) in small samples, leading to an overly trend-following (contrarian) investing style. Using quarterly performance and funds flow data for 752 hedge funds between 1994 and 2000, they conclude that: Keep Reading
