I researched this fund and am not overly impressed with it. The fund peaked a in 2009 and has declined steadily ever since. If you think it will recover, based on your research, this would be the opportune time to get involved. Otherwise, stay with something more stable. Even bank certificates of deposit are doing better.
The funds price is a bit high but that is just a per share price. Funds typically have per share prices that vary so it is not possible to say why this fund has such a high price.
Personally, I would not invest there.
I shy away from particular fund recommendations. That is the territory of investment advisers and consumers who do their own homework carefully. I do invest and will suggest you look into www.invesco.com and www.johnhancock.com. Both have a variety of funds to suit your particular preferences. I do not know enough about your lifestyle, assets, liquidity, and risk tolerance to go past this point. The two fund families noted above have worksheets on the web sites to help you make your own determinations if you prefer to avoid an investment adviser.
