I recently came across an intriguing idea at another website. In summary, the idea is that a stock is undervalued if it's Graham Number (found by multiplying the TTM P/E ratio by the TTM P/BV) is less than 22.5. The site said nothing about how to use this number to identify OVERVALUED stocks.
Does any other member have experience with this? Have any of you based picks on it,and if so how did you score on them?
