System uses funds' prior performance as investing guide


	Market observers have long noted that hot stocks tend to stay hot for a reasonably long time. Similarly, good performance in mutual funds tends to persist. The No-Load Fund Investor, a newsletter, has been tracking its Persistence of Performance strategy since 1991. The premise is simple: Each year, invest in the no-load fund that has had the best performance in the previous year. ("No-load" means that the fund charges no commission, or load.)
