Does anyone have opinions on the T. Rowe Price Retirement Funds. I am looking at possibly allocating 100% of my 401k to the 2035 or 2040 fund. As my trading experience is in day trading forex, I don't feel as knowledgable as I should about retirement investing. Seems like the Rowe retirement funds would be a good turn key low maintenance way to build up my 401k. Any advice would be appreciated.
