Stocks with a Value Line Safety Rank* of 3, 4 & 5 contribute to our performance measures for the Under- and Overvalued stock screens. Stocks with a Rank of 1 or 2 do not contribute to any appreciable amount. The latter are characterized as having above average market capitalization and yield. They account for 35 % of the observations in our monthly analysis of 500 equities over the last 11 years.
Using the quartile rankings for Valuation Return/Risk (VR) and the ratio of Estimated earnings/ Normalized earnings (E/M), we compare the average of next month's Relative Strength for quartiles 1,1 (Overvalued) vs 4,4 (Undervalued). As shown in the first example, the average Undervalued stock outperforms the S&P 500 by 44 basis points while the Overvalued underperform by 6 bp. The resulting spread of 49 bp translates into an annual 6.10%.
Screening
for Safety Rank of 1 and 2 only reduces the
spread to only 0.01% or 0.13% pa. This strongly suggests that, on average, these stocks are more efficiently
priced.
Screening for Safety Rank of 3, 4 and 5 only improves the spread to 0.57% or 7.03% pa. The rank of 3 alone, which has 58% of the observations, has a spread which is even higher at 0.63% or 7.84% pa suggesting that the middle ground, in terms of quality is the most inefficiently priced.

averaging two other Value Line indexes the Price Stability Index and the
Financial strength Rating. Safety Ranks range from 1 (Highest) to 5
