The Book to Market ratio is equal to a company's Book value per share / Current share price
It is the inverse of the price to book ratio. Thus be careful with your interpretation. For example a high Book to Market ratio shows that a company may be undervalued (the company’s market value is low compared to its book value). This would be the same as a low Price to Book ratio.

How to select the highest Book to Market companies
To find companies with the highest Book to Market ratio (low price to book) set the slider from 0% to 10%.
This may sound counter intuitive but we set the sliders so that selecting low percentages gives you most undervalued companies. If you are unsure if you are screening correctly select both book to market and price to book as output columns to compare the results with different slider settings.
