Is there such a thing as over-diversification?

Due to switching jobs and jobs switching fund management companies. I now have three retirement accounts with three different companies. I know diversification is important, but can my money be in too many places?

I'm 29 and just started working 5 years ago, so I have a long time until retirement.

It's mostly a matter of keeping track of your money. If they are actual retirement accounts, there may not be much in the way of tax paperwork for the next 30 or 40 years.

You can almost certainly consolidate accounts, but there are advantages to not having all your money in one place. Three accounts is probably not too much.

you bet ye.

I would recommend consolidating the 401K's from your prior employers into one rollover IRA, for ease of management/administration. I would keep the 401K with your existing employer in place so you can continue to make ongoing pre-tax contributions. Just make sure your asset allocation (mix stock/bond funds) across all of your accounts lead to the overal mix you want. At your age somewhere around 80-95% stock vs bonds, depending on your risk tolerance.

Your best bet would be to have an investment advisor look at your statements. Your old accounts can probably can be rolled over into one account and from there a proper asset allocation model can be set up for you. I don't know if I would do this myself. I would definitely have someone help me.

Yes. Check their quarterly statements to see what they are invested in to see if there is overlap.

There is over-diversification. According to many people diversification is good for diverse risk. Many consider around 20 stocks is the optimal. For more information check stockpickguide.com
