James Dines: A Living Legend? (Last Updated 5/9/08)

As suggested by reader Todd Saunders of Miami FL, we evaluate here the public stock market forecasts of James Dines since the second quarter of 2002. Evaluated predictions/recommendations come indirectly via MarketWatch columns, which have tracked his commentary occasionally in recent years. James Dines is editor of the The Dines Letter investing newsletter, published since 1960, which promises: "insights into investing and the economy, including timely stock, and precious-metals recommendations; economic forecasts; bull-and-bear market strategies and details that clarify today’s markets and economy..." The table below presents highlights from his public stock market forecasts and shows the performance of the S&P 500 index over the 21, 63, 126 and 254 trading days after the publication date for each item. Red plus (minus) signs to the right of specific items indicate those that the market has subsequently proven right (wrong). We conclude that:

• Much of James Dines' commentary focuses on gold and other precious metals, not covered in this assessment.
• A crucial element of his forecasting approach is mass psychology: market fluctuations derive from oscillations between mass fear and mass greed on the part of investors/traders. He also uses fundamental and technical analyses in constructing forecasts.
• Based on subsequent stock market performance and our judgments about his forecasts for overall stock market direction, James Dines' overall stock market forecasting accuracy rate is 50%, about average. However, his forecast sample size is very small, as is therefore our confidence in this conclusion.

James Dines offers a self-assessment of his forecasting track record, somewhat more positive than ours.

To augment the tabular summary below, we note that:

Peter Brimelow in MarketWatch (12/23/07) writes: "...[O]ne of 2006's top 10, The Dines Letter, comes in 12 from the bottom, down 11.4% vs. 7.51% for the dividend-reinvested Dow Jones Wilshire 5000."

Peter Brimelow in MarketWatch (1/1/07) writes: "This year, Dines is fourth among the HFD top-performers, up 48% vs. the dividend-reinvested Dow Jones Wilshire 5000's 16.54%. ...Even more impressive, over the last ten years Dines is up 17.16% annualized, vs. 8.16% for the total-return DJ Wilshire 5000."

In summary, James Dines' stock market forecasting accuracy rate is about average. Confidence in this conclusion therefore very low.
