Well, empty...It's a fairly well known fact that usually the higher the potential return-the higher the risk. Food for thought perhaps is front page of money and markets in sunday biz post...."pension fund to invest €600m in emerging markets"
The NPRF claims it will plough more money in, if they perform well enough.
All I can advise is research for yourself companies/countries involved in any fund, track record of fund, track record of company who is providing the fund and be prepared to face dips in markets, while sleeping ok at night.
