Mid-Year and Year-End Reviews Back to top

2009 Mid-Year Review Only time will tell whether we are experiencing a true turnaround, but the typical exchange-listed stock is up over 27% for the year, and many of the AAII stock screens have turned in performances that dwarf the broader market.

2008 Year-End Review For many investors, 2008 cannot end soon enough, with the S&P 500 index down 40.3% for the year (through early December). During periods like this, very few long-only stock selection strategies generate gains, including AAII’s stock screens. However, one screen proved to be the exception--the low price-to-book-value strategy developed by Joseph Piotroski gained 32.6% through December 5.

2008 Mid-Year Review So far this year, the market has been unable to overcome a series of obstacles, and as of the first week of June, the S&P 500 was down 7.3% This has carried over to the AAII stock screens: of the 56 screens tracked at AAII.com, only 20 are up for the year, although 43 are outperforming the S&P 500.

2007 Year-End Review The fiercest battle in 2007 was not among the strategists, but against the market itself. Nonetheless, the top strategist's win was decisive: The O'Shaughnessy Small Cap Growth and Value methodology closed the year up 43.9%.

2007 Mid-Year Review Most AAII stock screens are outperforming the broad market indexes. The Benjamin Graham Defensive Non-Utility screen is at the top of the first-half performance list, with a year-to-date gain of 35.4%. The O'Shaughnessy Tiny Titans screen tops the long-term list, with a cumulative gain of 3,290.9% since the start of 1998.

2006 Year-End Review It had its ups and downs, but the market had a thrilling end, as did most strategies during 2006. Of the 58 strategies tracked on AAII.com, only four failed to generate positive returns for the year. The value-oriented Enterprising Investor methodology of Benjamin Graham was the leading strategy for the year, while James O’Shaughnessy’s Tiny Titans growth and value strategy was the long-term winner.

2006 Mid-Year Review A mid-year review of the screens tracked on AAII.com shows a reversal of last year’s trend, with value strategies topping growth approaches, and small-cap screens outperforming mid- and large-cap strategies.

2005 Year-End Review It was a rocky start, but the market, as well as most strategies, finally found their footing in 2005, with 43 of the 54 strategies AAII tracks turning in a positive performance for the year. For the second year in a row, the Michael Murphy value-priced technology screen led the way, while the growth-and-value Zweig approach held its long-term standing.

2005 Mid-Year Review The year has been rough for value-oriented strategies relative to growth approaches, while strategies investing in smaller-cap companies have outperformed strategies that focus on larger firms.

2004 Year-End Review It was a mixed field on a changing track during the 2004 stock strategy performance derby. The top performer for the year was the only strategy during 2003 to show a loss. But the growth-and-value Zweig approach maintained its long-term lead.

2004 Mid-Year Review Thirty-four of the 54 strategies tracked on AAII.com showed positive gains for the first half of 2004. A look at the year-to-date winners.

2003 Year-End Review The Piotroski small-cap value approach and the Zweig growth and value strategy are the two big winners in AAII's annual comparison of major stock screening strategies tracked on AAII.com.

2003 Mid-Year Review The Foolish Small Cap 8 strategy shot past all of the other strategies in the first half of 2003, while the long-term leader in the growth category continues to be the O'Neil CAN SLIM approach.

2002 Year-End Review The S&P 500 experienced its third consecutive calendar-year loss. While in the past few years investors could take some solace from gains in small-cap stocks, it appears likely that small, medium and large companies will finish down on average for the year. Overall, smallercap stock indexes did perform better than larger-cap indexes and value strategies faired better than growth strategies.

2002 Mid-Year Review So far the top-performing screens during 2002 were also the leading strategies during 2001: The Joseph Piotroski screen led the value strategies, the Philip Fisher screen was the best growth and value approach and William O'Neil's CANSLIM approach led the growth group.

2001 Year-End Review For the last four years we have presented and discussed a new monthly stock screen on the Stock Screens segment of AAII.com, while simultaneously tracking the success and updating the results of all the previous screens. We now have 50 screens that cover the full spectrum of investment approaches, ranging from small-cap growth to large-cap value.

2000 Year-End Review The Stock Screens segment of AAII.com site has grown into a popular stopping point for association members. Over the last three years we have presented and discussed a new screen every month, while also updating and tracking the success of past screens.

1999 Year-End Review As 1999 wound down, we felt that it was a good time to look back at the performance of the market and the various stock screening strategies presented on our site. As is often the case, the year produced a number of big winners and losers.
