Are you wondering if you’re switching between mutual funds too frequently? Maybe you’ve heard horror stories about investors getting their accounts restricted for “excessive trading” but aren’t sure exactly what that means
Well, I’ve done the research and can tell you that the answer isn’t as simple as “once a month” or “four times a year.” Different fund companies have different policies, and breaking these rules can lead to serious restrictions on your account.
Let’s dive into what major brokerages like Fidelity and Vanguard consider “too much” when it comes to exchanging mutual funds, so you can invest without accidentally getting yourself in hot water!
What Is Considered “Excessive Trading” in Mutual Funds?
Before we get into specific timelines, we need to understand why fund companies even care how often you trade.
Here’s the deal: when you frequently buy and sell mutual fund shares, it creates problems for the fund manager and ultimately hurts other shareholders who are investing for the long term. Excessive trading:
- Increases transaction costs for the fund (like brokerage commissions)
- Disrupts the fund manager’s investment strategy
- Forces unwanted buying and selling of securities in the portfolio
- Can reduce returns for long-term investors
That’s why brokerages monitor trading activity and impose restrictions on investors who trade too frequently.
Fidelity’s Roundtrip Transaction Policy
Fidelity specifically monitors what they call “roundtrip transactions” So what exactly is a roundtrip?
A roundtrip at Fidelity is defined as: purchasing a mutual fund and then selling it within 30 calendar days in the same fund and account.
For example, if you buy shares of a Fidelity fund on May 1st and sell them before May 31st, that counts as one roundtrip.
Important things to know about Fidelity’s policy:
- They don’t use FIFO (First In First Out) when evaluating roundtrips
- Trades under $25,000 are exempt from roundtrip violations
- Transactions in Fidelity Money Market Funds don’t count
- Dividend/capital gains reinvestments sold within 30 days are exempt
- Automatic investments or withdrawals don’t count
Fidelity’s Violation Penalties
Fidelity has a tiered approach to penalties:
-
Fund Level Blocks: If you make a second roundtrip in the same fund within 90 days, you’ll be blocked from making additional purchases in that specific fund for 85 days. This block applies to all accounts under the same registration.
-
Complex-wide Blocks: If you make four roundtrip transactions across ANY Fidelity funds within a 12-month period, you’ll be blocked from purchasing ANY Fidelity fund (except money market funds) for 85 days. This applies to all accounts under your social security number.
-
Repeat Offenders: If you continue to violate the policy after your block expires, Fidelity may impose long-term or permanent blocks on your accounts.
Vanguard’s Frequent Trading Policy
Vanguard takes a slightly different approach to monitoring excessive trading, focusing on what they call “frequent trading” or “market-timing.”
Vanguard looks for:
- Excessive purchase and redemption activity within the same fund
- Excessive exchange activity between 2 or more funds within a short time frame
Exchange activity at Vanguard is considered excessive when it:
- Exceeds 2 substantive exchanges less than 30 days apart during any 12-month period
- Shows rapid movement into and out of several funds that violates the suggested holding periods in the funds’ prospectuses
Vanguard’s Violation Penalties
If Vanguard believes you’re engaging in frequent-trading practices, they reserve the right to:
- Decline your transactions
- Restrict your trading activities
- Block your account from making purchases
How to Avoid Getting Your Account Restricted
Now that we know the rules, let’s talk about how to stay in the clear while still managing your investments effectively.
For Fidelity Investors:
- Limit roundtrips to no more than 3 across all funds in a 12-month period
- Wait at least 30 days between buying and selling the same fund
- If you must sell within 30 days, keep the transaction under $25,000
- Consider using money market funds for short-term cash management (they’re exempt from restrictions)
For Vanguard Investors:
- Limit exchanges to no more than 2 exchanges less than 30 days apart in a 12-month period
- Respect the suggested holding periods specified in fund prospectuses
- Plan your investment strategy to require fewer exchanges
Other Tips for Mutual Fund Investors
Besides avoiding excessive trading, here are some other practices to avoid trading violations:
- Maintain sufficient funds in your settlement account to cover purchases
- Be aware of settlement dates for securities transactions
- Don’t sell securities that aren’t yet settled in your account
- Consider using margin investing for non-retirement accounts (if appropriate for your risk tolerance)
- Review settlement dates of securities sales that have generated unsettled credits
FAQ: Common Questions About Mutual Fund Exchange Frequency
Can I exchange mutual funds within my 401(k) as often as I want?
While 401(k) plans might have different rules than brokerage accounts, most still monitor for excessive trading. Check your specific plan documents, but generally expect similar restrictions to retail accounts.
Do these rules apply to ETFs too?
No! One big advantage of ETFs is that they trade like stocks and aren’t subject to these same excessive trading restrictions. If you need more frequent trading flexibility, ETFs might be worth considering.
What if I need to make adjustments to my portfolio more frequently?
Consider these strategies:
- Use money market funds for cash management
- Implement portfolio changes gradually over time
- Use ETFs for portions of your portfolio that might need more frequent adjustments
- Spread investments across different fund families
Do automatic rebalancing programs count as roundtrips?
Generally, systematic programs like automatic rebalancing don’t count toward roundtrip limits. At Fidelity, for example, systematic withdrawal and contribution programs don’t count toward roundtrip limits.
Real-World Example: Why I Got Stuck in a Trading Restriction
I’ll share a personal story. Last year, I got caught in Fidelity’s trading restriction because I wasn’t paying attention to their roundtrip policy.
I had bought shares in a sector fund, and then the market suddenly dropped. I sold within 2 weeks to cut my losses. Then, when things stabilized, I bought back in. About three weeks later, the sector rallied strongly, and I decided to take profits.
Boom! Second roundtrip within 90 days. I was blocked from buying that fund for 85 days.
Two months later, I made similar quick moves in three other funds, not realizing these were all adding up. That’s when I got hit with the complex-wide block, preventing me from buying ANY Fidelity fund for 85 days.
The lesson? I should have paid closer attention to the roundtrip count and either:
- Waited 30+ days before selling
- Used ETFs for my more active trading
- Kept my transactions under $25,000
The Bottom Line: Finding the Right Balance
The simple answer to “how often can I exchange mutual funds” is:
- At Fidelity: Avoid more than 3 roundtrips in 12 months, with no more than 1 roundtrip in the same fund within a 90-day period
- At Vanguard: No more than 2 exchanges less than 30 days apart in a 12-month period
However, the more practical answer is: mutual funds are designed for long-term investing, not frequent trading. If you find yourself wanting to trade frequently, you might want to consider whether:
- Your investment strategy aligns with mutual funds as an investment vehicle
- ETFs might be a better option for portions of your portfolio
- You need to adjust your overall investment approach
Remember, these restrictions exist to protect all shareholders from the negative impacts of excessive trading. By understanding and respecting these policies, you can avoid restrictions while still effectively managing your investments for the long term.
