Definition of Portfolio Turnover Rate

The portfolio turnover rate is a measure of how frequently assets within an investment portfolio are bought and sold over a specific period. It is expressed as a percentage and helps investors evaluate fund management strategies and trading activity.

For example, if a mutual fund has a 50% portfolio turnover rate, it means that half of its holdings have been replaced within the year.

Purpose of Portfolio Turnover Rate in Investing

The portfolio turnover rate is essential for the following:

• Assessing the trading activity of a mutual fund or investment portfolio.
• Understanding the impact of transaction costs on investment returns.
• Evaluating the investment strategy of actively managed funds.
• Analyzing tax implications related to capital gains.
• Comparing funds to determine long-term investment efficiency.

How Portfolio Turnover Rate Is Calculated

Portfolio Turnover Rate Formula

Portfolio Turnover Rate = (Lesser of Total Purchases or Sales / Average Portfolio Value) × 100

Example Calculation

• A fund has $2,000,000 in total sales and $3,000,000 in total purchases, with an average portfolio value of $5,000,000.
• Turnover Rate = (2,000,000 / 5,000,000) × 100 = 40%.

This means 40% of the fund’s holdings have been replaced during the period.

Types of Portfolio Turnover

High Portfolio Turnover

• Frequent trading with short-term positions.
• Can lead to higher transaction costs and capital gains taxes.
• Example: A hedge fund with an 80% turnover rate actively trades stocks to capitalize on short-term price movements.

Low Portfolio Turnover

• Minimal trading activity with long-term investments.
• Generally results in lower fees and greater tax efficiency.
• Example: A passive index fund with a 5% turnover rate primarily holds stocks for the long term.

Portfolio Turnover Rate vs. Expense Ratio

Feature	Portfolio Turnover Rate	Expense Ratio
Definition	Measures how frequently assets are traded in a fund	Represents the total operating costs of a fund
Impact	Affects transaction costs and tax efficiency	Influences net returns due to management fees
Example	A fund with a 60% turnover rate actively trades holdings	A fund with a 0.75% expense ratio charges investors yearly on total assets

Example: A fund with high turnover and a low expense ratio may still have hidden trading costs, reducing net returns.
