Hi X.. The VWave is calculated by: 1. Dividing the Value Line Appreciation Potential by 2.34 (the highest VLAP on record was 234%). 2. You then subtract from 100 to get the 'old' Value Wave. 3. Finally you multiply #2 times 0.73125 to get the new Value Wave. The Value Line Appreciation Potential (VLAP) is published weekly in Value Line. Hope this helps. Take care. Jon
