We suggest that you use Book to market
You can use Price to Book in the screener but we suggest you use the Book to Market (inverse of price to book) as it gives you better screening results. This article explains why: Why use book to market and not price to book?
All ratios are calculated on a trailing 12 months (TTM) basis.
This means the last twelve months (not the company’s financial year) is compared to the same period in the past. We do this to make sure that the screener data includes the latest, most up to date, financial results of the company.
How to use the ratio
Available as a screening ratio: No (Use the Book to Market ratio in stead)
Available as an output column ratio: Yes (Look for it under the Valuation heading)

To find companies with the lowest Price to Book Ratio:
- Select Book to Market ratio in the screener set the slider from 0% to 10%
