No only are there no or low fees at Vanguard, you will be part owner of the company. Vanguard is owned by the shareholders. Jack Bogel specifically set it up this way.
After years of trying numerous approaches to money management, Peter Lynch do it yourself with Charles Schwab, Jim Creamer and finally the Vanguard Appproach. When I moved all my money with them I discovered the savings are even greater than I imagined. Need an ETF, there is no fee to by a Vanguard ETF. Need or want to buy some stocks, for me I don't think I ever paid a fee. I'm not exactly sure why that is but it could have to do with how much money I have there. Need a good mutul fund that has low expenses they have them.
Not only are the fees low, their investing approach is probably the best for most people including me. Who, I'll refer you to the Bogelheads blog, they explain it much better than I can. To sum it up it is very hard to beat the market over the long term.
As part of my investment journey I tried investing with the investment star manager of the moment with usually the same result. What is the investing star of the moment, you can find this person usulally on the cover of Forune or articles about them in business publications. CGM's manager was on the cover of Fortune, I invested heavily in that fund and the fund blows up. Same thing with Dodge and Cox, boom. They were investing in GM right before it went bust. Oakmark's Bill Nugen was a star at one time, the guys keep touting Washington Mutual for years right up to it went bust. It was his largest holding. Jim Creamer, I purchased his Action Alerts Plus, this is where he manages a portfolio and sends out E-Mails about his trades. To his credit he has his record against the S&P 500 on his site and guess what, the S&P wins.
The one approach that worked for me was the Peter Lynch approach. I picked the stocks in the 90s, I had value line and used Standard and Poors. I hit it big on a few stocks in the 90's although I later came to realization a lot of folks were hitting it big then, although I was hit it bigger than most and I did get out with a lot in my pocket. I don't recommend this because it is a really a full time job, and even at that, you are probably better long term in the S&P 500 index.
Some good books on this are out there. Any of Jack Bogels books and a Random Walk down Wall Street. Stocks for the long run is another good one by Jeremy Siegel.
