VectorVest favors the purchase of safe stocks. Safe stocks are those of large companies with outstanding records of financial performance. They have low debt to equity ratios, above average price stability, and a propensity to rise in price. VectorVest also considers other factors in assessing stock safety. These are described in the chapter entitled Stock Safety: The Missing Link in Dr. DiLiddo’s book Stocks, Strategies and Common Sense. A complete analysis of stock safety is contained in an indicator called Relative Safety, RS. On a scale of 0.00 to 2.00, values of Relative Safety above 1.00 are favorable. Values below 1.00 are unfavorable.
