Here are the lowest Price/Book shares on the JSE as at 9 Jun 2009. They effectively form the 1st low price-book decile. Portfolios are normally constructed from the first 10 or 20 shares (as in our model portfolios) for a low price-to-book strategy.
Note that quite a few issues here are going through financial stress. That is why some investors prefer the Piotroski strategy which focuses on low price/book shares but with a sound financial position.
