Portfolio Turnover Ratio: How Often a Fund Changes Its Holdings

A turnover ratio is usually shown as a percentage, or sometimes as a number of times. Roughly, it compares how much the fund bought or sold during the year with the size of the fund.

A low figure suggests that most companies stayed in the portfolio all year. A high figure suggests that a large part of the portfolio was replaced, perhaps more than once.

Suppose two large cap funds both hold similar types of companies. One has a low turnover: most of its holdings have been the same for years. The other has a high turnover: it has replaced a large part of its portfolio this year.

The first is likely to feel more predictable. The second may be trying to catch changing trends. Neither is wrong, but you should know which one you are buying.

Most fund houses show the turnover ratio on the monthly fact sheet, usually in the section with portfolio statistics or risk measures. Our page on the fact sheet explains where to look.

Check the period it covers, usually the last twelve months, and compare it with the same fund figure from a year ago to see if anything has changed.

A low number does not mean a fund is lazy, and a high number does not mean it is skilful. Turnover describes how a fund works, not how well. Always look at results against the benchmark over several years alongside it.

Think of it as a description of style, useful for understanding what you own.

A low turnover fund tends to pick companies and hold them for years. This is often called a buy-and-hold approach.

It usually means lower trading costs and a more predictable portfolio. Many long-term investors like this style, because what they bought into stays broadly the same.

A high turnover fund changes its holdings frequently. The manager may be reacting to market movements, chasing short-term opportunities, or rotating between sectors.

That is not automatically bad. Some strategies naturally trade more. But it means the portfolio you see today may look quite different in six months.

Every time a fund buys or sells shares, it pays brokerage and other transaction costs. These trading costs are generally not included in the expense ratio you see.

So a high turnover fund may cost more in practice than its expense ratio suggests. Our page on expense ratio explains what is and is not included.

Different fund types naturally have different turnover. Index funds usually have low turnover, since they only trade when the index changes. Arbitrage funds have very high turnover by design, because their strategy involves constant buying and selling.

So compare turnover only between funds in the same category. Our pages on index funds and arbitrage funds explain why their turnover differs so much.

Mutual funds in India do not pass tax on their internal trading to you each year in the way some other countries do. You are taxed when you redeem your units.

So turnover mainly affects you through trading costs and style, not through yearly tax bills. For your own tax position, our page on mutual fund taxation explains the structure.

A sudden jump in turnover can be a sign that something has changed: a new fund manager, a change in strategy, or a reaction to a difficult period.

If you notice turnover rising sharply, check whether the manager or objective has changed. Our page on the fund manager explains why a change in manager can matter.

Not necessarily. Some high turnover funds have done well, and some low turnover funds have done poorly. Turnover is one signal, not a verdict.

What matters most is how the fund has done against its own benchmark over several years, after costs. Our page on the benchmark explains how to compare properly.

• Compare funds within the same category.
• Use turnover alongside returns, risk ratios and costs.
• Prefer consistency: a fund whose turnover stays stable is easier to understand.
• Watch for sudden changes that may signal a new approach.

Our page on Sharpe ratio and standard deviation covers other numbers on the same fact sheet.

• Is this fund turnover high or low compared with others in its category?
• Has it changed sharply in the last year?
• Does the fund manager explain the strategy in the fact sheet or scheme documents?
• Do the returns, after costs, justify the trading?

Debt funds also trade, but turnover is less commonly discussed for them. For debt funds, numbers like YTM, duration and credit quality usually matter more.

Our page on YTM and modified duration explains those.

You do not need to check turnover every month. Once a year, during your review, glance at it alongside performance and costs.

Our page on how to review your portfolio gives a simple yearly checklist.

• Turnover ratio: how much of the portfolio was traded in a year.
• Low: buy-and-hold, lower trading costs.
• High: frequent trading, possible hidden costs.
• Compare within the same category, alongside other numbers.
