#1. - I like this one better, but both Bull and Bear need to be within icon. The arrows are creative, I would never have thought of that, but i prefer the name to be easy to read. (My target market is going to be wearing bifocals!)
#2 - I like the colors but the bull and bear look too cartoonish for me; The name obscures the icon, I prefer more direct labeling. Thank you.
#7 - The Bull and Bear need to be more defined, I just noticed that it is 1/2 profile of each. (I thought it was all one.) - I like the circular design better than square. Thank you.
