You should know that the mutual funds in your plan may disallow or penalize certain actions; your plan administrator, with your employer's input, may have set other rules. Check with HR to find out what applies to you, but beware these often-restricted moves: ### Making a "roundtrip" transaction **The rule:** Funds or administrators may limit your ability to sell out of a fund and then buy back in within a short period, called a roundtrip. For example, the first time you sell a Fidelity fund and then reinvest more than $1,000 into the same fund within 30 days, you'll get a warning; subsequent roundtrips result in restrictions on how often you can trade in the future. (The Fidelity plan at Time Inc. -- Money's parent company -- limits employees to one trade a quarter after the third roundtrip.)

The lack of liquidity could result in such funds taking a big performance hit as a result of short-term trading. ### Buying too much company stock **The rule:** Public companies often put a cap on how much employer stock that workers can own, says Powers. The restriction is usually built into the plan, so that you wouldn't be able to invest more than, say, 25% of your money with your company. **The reason:** In a post-Enron world, says Powers, 401(k) plans are designed to prevent employees from holding 100% of their portfolio in their employer's stock. ```json { "@context": "https://schema.org", "@graph": [ { "@type": "BreadcrumbList", "@id": "https://money.com/how-to-get-in-trouble-in-your-401k/#breadcrumb", "itemListElement": [ { "@type": "ListItem", "position": 1, "name": "Home", "item": "https://money.com" }, { "@type": "ListItem", "position": 2, "name": "Retirement", "item": "https://money.com/retirement/" }, { "@type": "ListItem", "position": 3, "name": "401(k)", "item": "https://money.com/401k/" }, { "@type": "ListItem", "position": 4, "name": "How to Get in Trouble in Your 401(k)" } ] }, { "@type": "WebSite", "@id": "https://money.com/#website", "url": "https://money.com", "name": "Money", "publisher": { "@id": "https://money.com/#organization" } }, { "@type": "WebPage", "@id": "https://money.com/how-to-get-in-trouble-in-your-401k/#webpage", "url": "https://money.com/how-to-get-in-trouble-in-your-401k/", "name": "How to Get in Trouble in Your 401(k)", "isPartOf": { "@id": "https://money.com/#website" }, "datePublished": "2014-05-07T01:14:35.000Z", "mainEntity": { "@id": "https://money.com/how-to-get-in-trouble-in-your-401k/" }, "inLanguage": "en-US", "breadcrumb": { "@id": "https://money.com/how-to-get-in-trouble-in-your-401k/#breadcrumb" }, "dateModified": "2024-04-14T08:48:00.000Z" }, { "@type": "Article", "headline": "How to Get in Trouble in Your 401(k)", "articleSection": "Retirement", "image": [ { "@type": "ImageObject", "url": "https://img.money.com/2012/01/929370921.jpg", "width": 1632, "height": 2048, "caption": "1954: John Foster Dulles, U.S. Secretary of State" } ], "author": [ { "@type": "Person", "name": "timestaff", "url": "https://money.com/author/timestaff/", "@id": "https://money.com/author/timestaff/#author" } ], "publisher": "https://money.com/#organization", "datePublished": "2014-05-07T01:14:35.000Z", "description": "Make a trade now and again?
