The higher the Fixed Asset Turnover ratio, the more effective the company's investments in Net Property Plant Equipment have become. You may have to search for the explanation in the financial statements to find out what investments were made, as large capital investment purchases may not immediately yield higher sales.
It may take a year or multiple years companies to fully utilize these large investments. If you can clearly see the company invested in major improvements heavily one year, it would be wise to watch the Fixed Asset Turnover closely over the next year or more to gauge how well those investments actually helped the company.
