401k Profits shows you a simple model for investing your 401k (or IRA, Roth or other retirement) plan that requires less than one minute of your time per week to earn 16% per year gains. Think simple, think easy. You get a free update sent once each weekend telling you what the 401k Model is doing and then you can adjust your own 401k account to do the same. But the Model only makes changes, on the average, once every 11 weeks. That means for 10 out of 11 weeks you take 5-6 seconds.
