Stock Turnover: Calculation, Liquidity Interpretation, and Limitations
Summary
The document explains turnover as the number of shares traded during a period divided by the average number of shares available to trade, expressed as a percentage. It illustrates the calculation with a quarterly example in which traded volume is twice the average share count, producing turnover of 200%. Turnover is presented as a measure of trading activity and a rough indicator of liquidity.
Higher turnover may make shares easier to trade, but the text also associates it with greater price variability and notes that unusually high activity can reflect speculation or manipulation. Lower turnover may indicate less market interest or longer holding behavior, while trading in less liquid shares can have greater price impact. The article gives illustrative high and low annual turnover figures and recommends considering turnover alongside fundamentals and market conditions. It does not establish universal thresholds or demonstrate a standalone trading strategy; interpretation depends on the measurement period, share-count definition, and security.
Key ideas
- Turnover is traded share volume divided by average shares available during the same period, multiplied by one hundred percent.
- A turnover value indicates trading volume relative to the share base rather than the number of distinct investors.
- Higher turnover can indicate greater activity and easier execution, but may coincide with higher price variability.
- Low turnover can signal subdued activity and may increase the price impact of trades.
- Turnover is a contextual liquidity measure, not a standalone buy or sell signal.
