Taobiz explains Turnover
1. In accounting, turnover often refers to inventory or accounts receivable. A quick turnover is desired because it means that inventory is not sitting on the shelves for too long.

2. In a portfolio, a small turnover is desired because it means the investor is paying less in commissions to the broker. It is called "churning" when a broker unethically generates numerous trades solely in order to increase commissions.
