What they argue
- Combining smoothed rates of change over several time frames into one weighted indicator (KST) gives a clearer read of the trend and its reversals than any single momentum measure.
- Asset allocation should rotate between stocks, bonds and commodities according to the stage of the business cycle, the idea behind the Pring Turner approach and the Dow Jones Pring U.S. Business Cycle Index (2012).
