Do Commodity Trading Advisors (CTAs), generally associated with the “managed futures” hedge fund style, successfully time their chosen markets? These traders take long or short positions in investment vehicles with low transaction cost (such as futures contracts) to exploit trends in commodity prices, exchanges rates, interest rates and equity prices. In the February 2008 version of their paper entitled “Market Timing of CTAs: An Examination of Systematic CTAs vs. Discretionary CTAs”, Hossein Kazemi and Ying Li investigate the return and volatility timing ability of CTAs and examine whether there is a difference in market timing abilities between systematic and discretionary traders. To this end, they develop a set of risk factors based on returns from the most heavily traded futures contracts. Using monthly, net-of-fees return data for 1994-2004 (encompassing 278 live and 622 defunct CTA funds), they conclude that: Keep Reading

Does the Wall Street Journal’s SmartMoney Fund Screen help its readers beat the market? In the February 2008 version of their paper entitled “Do Mutual Fund Media Recommendations Hold Value? An Empirical Analysis of the Wall Street Journal’s SmartMoney Fund Screen”, George Comer, Norris Larrymore and Javier Rodriguez employ two methods to test the performance of mutual funds listed at the ends of the Wall Street Journal’s SmartMoney Fund Screen columns during the year before and the year after publication. These weekly columns flag top performing mutual funds based on criteria such as fund objective, historical returns and expense ratios. The authors collect and assign the funds in these lists to one of five fund categories: domestic equity, international equity, sector, hybrid (asset allocation and balanced funds) and fixed income. Using daily returns for 399 mutual funds (263 unique) listed during 2005, they conclude that: Keep Reading

In considering the stock ratings of expert analysts, should investors focus more on the level of the ratings or changes in ratings?

Using real-time analyst stock ratings from two databases spanning 1986-2006 (more than 1,000,000 ratings) and contemporaneous daily stock returns, they conclude that: Keep Reading

Mutual fund investors have two ways to beat the market: (1) pick the right funds, and (2) time their purchases and sales. How effectively does the average fund investor execute the latter goal? In their December 2007 paper entitled “Investor Timing and Fund Distribution Channels”, Mercer Bullard, Geoff Friesen and Travis Sapp examine the investment timing performance of equity mutual fund investors and the relationship of this performance to the fund distribution channel. Using data on returns and funds flows for 6,164 U.S. equity mutual funds during 1991-2004, they conclude that: Keep Reading
