What is the Portfolio Turnover Ratio?

The measurement of the percentage of a portfolio’s holdings that are replaced in a specific period is identified as the Portfolio Turnover Ratio. The frequency with which a fund manager or an investor buys and sells investments reflects how the ratio is calculated. It also helps in understanding and making a foreign direct investment.

A higher turnover ratio means:

A lower turnover ratio means:

Fewer transactions

Lower trading activity

The ratio helps investors understand whether a mutual fund follows an active or passive investment approach.

Portfolio Turnover Ratio Formula

Below is a formula, which is used to calculate Portfolio Turnover Ratio. The purchases and the sales are used to calculate the lowest value so that there is no double-counting. It further helps in the development of business acumen to make investment decisions.

Portfolio Turnover Ratio = (min (Purchases, Sales)/ Average Net Assets) / 100

Where:

Purchases = Total securities purchased during the year
Sales = Total securities sold during the year
Average Net Assets = Average value of assets managed by the fund

The lower value between purchases and sales is generally used to avoid double-counting. The final answer is expressed as a percentage.

Components of Portfolio Turnover Ratio

Several important components are involved in calculating and understanding the Portfolio Turnover Ratio. Here are the significant components of the Portfolio Turnover Ratio:

Purchases of Securities

Government securities

Sales of Securities

It represents the total value of securities that have been sold annually. Both purchases and sales influence turnover levels.

Average Net Assets

Average Net Assets represent the average market value of assets managed by the mutual fund over a period. It acts as the base value for calculating the turnover percentage. Large asset values with low trading activity generally result in lower turnover ratios.

Percentage Representation

The Portfolio Turnover Ratio is expressed as a percentage. Here are some of the examples of the percentage representation:

20% turnover ratio = Low trading activity
100% turnover ratio = Entire portfolio replaced once during the year
150% turnover ratio = Holdings replaced more than once
