What does a low inventory turnover ratio (compared to competitors) imply? What could be the reasons for the company's lower ratio? I got a company's inventory turnover ratio of 17.81 , 17, and 17.45 for years 2015-2017 (but the competitors' average is 33.88 , 29.9, and 36.13).

If based on the trend (years 2015-2017) of the company itself, what could be the cause of higher ratio from 2016-2017?

Thank you, I'm really having a hard time analyzing this part of the financial report.
