There are many sources of information to assist in making investment decisions, including material published by public agencies such as the Office of the Retirement Commissioner, and by reputable members of the savings and investment industry. There is also the advice of professional experts.
Naturally, the quality of advice is only as good as the quality of the person giving it, so if an investor chooses to use an investment adviser, the investor would be wise to check the adviser's qualifications and accreditation, experience, track record and independence.
