No. In fact a lot of mutual funds are the absolute worst offenders since they like to backload fees, or at least used to. It should be illegal and I can only hope it is now. Also, good luck trying to figure out what you're actually being charged.
Even index funds can have high hidden fees.
That said, Vanguard is essentially a large family of mutual funds. But until you have a little more confidence in investing, stick with the index funds. If you're feeling brave, think about some broad industry funds - tech, healthcare, etc. Just realize that the betas on those are probably going to be higher (or lower) than the market generally.
Beta is just a measure of volatility. So tech for example is going to have a pretty high (>1) indicating it both moves up AND down more than the market as a whole. But others, say utilities, is going to have a relatively low beta. So if you're a wary investor, stick with either general index funds or ones with a beta <1.
Stay away from derivatives like options and futures contracts unless you like losing lots of money very quickly.
