My mother, 59 years old, wants to invest money for her retirement as well as for her children. Which one do you think is the best investment for her?

Thank you and if possible, please let me know the product name that you suggest for. =)

Well, I need more info. Does she have any existing life insurance? How much? If she has enough coverage then investing in a good mutual fund like washington mutual or van kampen or fidelity (no load) are good bets. Diversify. Dollar cost average. Be moderately aggressive because of her age. Maybe 50% aggressive (stocks) 50% safety (bonds). Some mutual funds like washington mutual will do all of this inside of one fund (no tax consequences for you. Also, have her check out 403b investing (pre-tax) if it is available through her employment (teacher, hospital, etc.) Happy investing! 401k if available too! Almost forgot, never mix your investments with your retirement products. Get cheap term life insurance and invest what's left over in good mutual funds. She will do well, especially in this reduced market. Things are on sale, just ready to climb int he long haul.
Look at the history of the funds 5, 10, 20 years or more. Look for the steady growth funds that have weathered the storms. Have fun! Sieze the day!
