What is one of the best mutual funds to invest in?

Something "no-load"

Even with mutual funds I would diversify a little. All of the growth is in China, LA, Emerging Markets. Here's 3 great no-loads: AIM China, Direxeon LA, Profunds Ultra-emerging (all over 100% ytd and fundamentals haven't changed)

You might also want to consider some ETFs, which are less restrictive, but have underperformed their fund counterparts somewhat: ishares FTSE China, ishares MSCI Brazil, and Marketvectors Steel.

Lots and lots of choices.

I like Fidelity Contrafund because it holds up well in bear markets and performs decently in bull markets. FCNTX.

No load, 0.98% expense ratio.

First Eagle Global Investors A shares if the fund is open to new investors.

Go to www.morningstar.com. Use their fund screener to looks for funds that meet your needs.

Look for something " international" or " global" in scope. I've had great returns with FEMKX...( Fidelity's emerging markets) and I expect them to continue...maybe drop off slightly but still very respectable ( 20% to 25%)
Another angle is trading ETF's... EWA ( Australia) has been terrific due to their metal and materials trade with China, India and growing Asian countries ...in the same vein the ETF in " metals"...XME has done well, also.
