| HAUGEN SYSTEMS PORTFOLIO BACKTESTS | ||||||||||||||
| In these backtests, we started with a universe consisting of the top 1,000 U.S. stocks (by market capitalization). | ||||||||||||||
| Starting with data from January 1996, we sorted based on the indicated methodology and took the top 50 | ||||||||||||||
| stocks, which ranked highest under the methodology being tested. For the following month and for each month thereafter, | ||||||||||||||
| we rebalanced the portfolio by selling the four stocks with the lowest ranking. The four exiting position's value was | ||||||||||||||
| then calculated. We distributed the proceeds evenly among the four new stock picks, again which ranked | ||||||||||||||
| highest under the methodology being tested. | ||||||||||||||
| Once the backtest was complete, we linked the returns to get annualized results. Then we ran 11 more tests, | ||||||||||||||
| with each test beginning in a different month. For example, to see how the strategy would do if the test began in | ||||||||||||||
| February, we formed a portfolio of 50 stocks beginning in February, 1996; rebalanced four stocks each month, and | ||||||||||||||
| linked the returns. | ||||||||||||||
| The example worksheet shows how portfolios were compiled in the backtests. | ||||||||||||||
| The following two worksheets present the results from all 12 backtests for each methodology. In all the tests, except | ||||||||||||||
| for the ranking procedure, the exact same parameters were employed: the population consisted of the top 1,000 stocks, | ||||||||||||||
| 50 stocks were held each month, and four stocks were rebalanced each month. | ||||||||||||||
| The cumulative worksheet graphically shows how four selected methodology's portfolios did over time. | ||||||||||||||
| Note: We have not made an attempt to replicate Greenblatt's strategy; for example our return on assets factor | ||||||||||||||
| does not include earnings before interest and taxes, but is rather the ratio of operating income to assets. In addition, | ||||||||||||||
| our earnings yield does not use enterprise value, but is rather the ratio of most recently reported 12 months earnings per | ||||||||||||||
| share to the current market price. | ||||||||||||||
| Differences in stock populations, numbers of stocks included in portfolios, ranking and rebalancing procedurecs betweeen | ||||||||||||||
| ours and those published in the Greenblatt book are due to differences in stock populations, ranking procedures, and time- | ||||||||||||||
| periods. | ||||||||||||||
