I want to open up a 403 (b) and was given a list of vendors from my school district. I want to invest in something I understand so I crossed off all the life insurance and annuities companies, as well as companies that have websites that are hard to navigate. I am left with Oppenheimer Funds Distributer and American Century Investments. Do any of you have feedback on either of these companies? If so, are there any funds you recommend? I am used to investing with Vanguard and this is a new experience for me. Any advice would be much appreciated.
