I have one CD coming due next week, and all the rest coming due in 2015.I can let the CD roll at 1.55%, move it to another bank I already have a relationship with at 2.15% or 2.27%......or, I can move it to mutual funds and be fairly sure of getting at least 10% this year.My investment plan is about 25% savings/CD's and 75% mutual funds/individual stocks and moving it won't really throw that off--but I wouldn't do it again next year.Opinions? Go for better gains? Stay safe?

I can move it to mutual funds and be fairly sure of getting at least 10% this year.
Where you getting this idea that mutual funds are going to have a "sure" 10% return for this year? Are you able to predict the future?
For the past 10 years starting in 20014, the annual return for VTI the Vanguard Total Stock Market ETF has returned 12.79%, 6.31%, 15.69%, 5.37%, -36.98%, 28.89%, 17.42%, 0.97%, 16.45%, 33.45%.
You can hit the jackpot and get the 33.45% like last year 2013 or get -36.98% like 2008.

Age, emergency fund, debt obligations, job security, family size, income, size of budget, retirement funds and much more should be taken into account. Not just the allocation of your savings.
