I frequently mention that, when selecting mutual funds, it’s generally advantageous to look for funds with low turnover.
What I’ve noticed from comments on the blog and emails I’ve received is that some investors seem to miss the fact that the same thing applies to our own portfolios. Generally speaking, increased turnover is a bad thing.
Increased Costs
Most obviously, increased turnover leads to increased transaction costs:
- If you purchase individual stocks or bonds, each transaction comes with a cost. Even if you’re using a discount brokerage firm, those $7 trades begin to add up.
- If you jump between funds, there may be a transaction cost (depending upon which funds you use and how quickly you sell them after buying them).
- If you’re investing in a taxable account, turnover means incurring capital gains taxes earlier, which is harmful to returns.
Increased Risk
Less obviously, increased turnover in your portfolio creates a cost in terms of extra risk you take on.
For example, there’s a high probability that if you hold a stock-based mutual fund for a long enough period of time, you’ll enjoy a positive rate of return. However, if you constantly jump back and forth between various mutual funds, it’s no longer such a sure thing.
Increased risk and increased costs, without an increase in expected return. What’s not to love?
The alternative: “Don’t just do something, sit there!”
