<prompt> Human: Howdy, So, I use Fidelity through my company, and I have 5 different funds, one which is my company stock, 4 others are actual mutual funds. Over the years, I occasionally move large chunks of these funds around, perhaps from one fund to another, or from a fund into a low volatility fund when Im concerned about the market.I also have the benefit of working for a company that is growing rapidly, so I put money into the company stock fund, and will move it back out occasionally when we may be a little bearish.All that said, Ive never seen, nor heard of, nor been charged with any kind of fee for moving these guys around over the years. Is there some hidden fee thats going to come back and bite me when I retire later in life, or is this just par for the course so to speak?Thanks in advance.  <response>: Most 401k plans do not charge a fee for transfers from one investment to another. Occasionally some funds in the plan may impose a fee if you trade in and out of that fund too quickly, but these should be well identified and timeframes clear.
