I was reading an interesting post by DR. Bret Steenbarger at http://www.traderfeed.blogspot.com/ on the above subject and decided to look up MUB. As everyone in this business knows, timing is the key to success, and since my own blog deals with how to trade (and perhaps invest) by choosing low risk levels, I decided to spend a short time showing you how I would approach investing in MUBs. Take a look at these three charts and let me know what you think. mub-15-oct-2008
