Fellow Shareholders,
I am pleased to present the semiannual report for The Oakmark Family of Funds. This past quarter was one which generally rewarded the patient investor. The individual fund results, as well as the portfolio managers commentaries, are presented in the following sections of this report.
MARKET TIMING
As value investors, we firmly believe that over time security prices and underlying company values converge. Experience has taught us that while the time frame for this convergence is very uncertain, inevitably patience is rewarded. But what is the potential cost of not being patient and staying the course during volatile periods? As a long-term investor, the short-term decision to temporarily get out of the market requires two correct decisions.
The first relates to identifying the right time to sell, with its attendant costs and tax implications; and, the second relates to choosing the right time to buy back in. Several years ago the folks at the University of Michigan looked at one of the best bull market periods, 1982-1987, and did a piece on The Penalty for Missing the Market which is summarized in the following table:
| The Penalty for Missing the Market (1982-1987 Bull Market)* |
|
|
|
|
| Period of Investment | S&P 500 Annualized Return |
| Full 1,276 Trading Days | 26.3% |
| Less the 10 Best Days | 18.3 |
| Less the 20 Best Days | 13.1 |
| *Aug 12, 1982-Aug 25, 1987 | |
Similarly, we tested the performance of The Oakmark Fund for the period since inception, August, 1991 through April 30, 1997. The results presented below are remarkably similar to the University of Michigan study.
| The Potential Penalty for Trading In and Out of The Oakmark Fund |
||
|
|
||
| The Oakmark Fund | Annualized | Total |
| Full 1,447 Trading Days | 29.6% | 342% |
| Less the 10 Best Days | 18.7 | 167 |
| Less the 20 Best Days | 14.8 | 121 |
Both of the above studies show that a significant part of the long-term result may be affected by being out of the investment for a very short period. The elimination of less than 2 percent of the trading days reduced the cumulative return by nearly 65%!
While no one expects to be unlucky enough to miss all these days, the potential penalty for missing just a few is very high. As we have learned from recent experience, there will be times when increased market volatility will test your resolve to be long-term investors. Once you have made the appropriate asset allocation to stocks and own a fund you have confidence in (hopefully one of The Oakmark Family!), dont sabotage the potential return by short-term trading.
In our ongoing efforts to upgrade our level of service and reduce costs, we have created our own Web site, www.oakmark.com. The Funds prospectus, application, quarterly report, and daily net asset values are available on the site. We have also enhanced our audio response system and are enclosing a brochure that describes its use, including all the new features.
Thanks for your support and confidence in us.Very truly yours,

VICTOR A. MORGENSTERN
