5% CD's Are Good Indeed. If You Are Close To Your Time Horizon (If You Can Get 5% CD's) It Might Be The Place To Invest. If You Are More Than 10 Years Away From Your Time Horizon You Might Want To Stick With Wellington. The Possible Higher Yields Its Stock Market Exposure Might Get You Outweigh The FDIC Insured CD's If You Have Enough Time.
Why not both? CDs and Wellington represent different strategies and have different risks. In my opinion, Wellington will do better in the long run because it is two thirds value stocks. Over the past couple of years Welling ton has done much better than 5%. The published yield is the dividend yield. Price appreciation is not part of that. Nor are the effects of being a balanced fund.
