Both of these designs...#14 and #15...are very interesting. #15, however, is a little too square looking and seems more appropriate for a computer or technology company than a professional investment firm.
Regarding # 14, I like the graph design and the thin line between the graph and the name. Maybe the lines inside the graph could be angled to show an upward angle left to right. Also, please try with a slightly brighter green. In the name, please try a richer and slightly darker blue and add a little space between the two lines.
