FN logo

The 2 logos remind me strongly of the logos of the publishing company Börsenmedien AG and the newspaper Finanz und Wirtschaft.

The logo above is one of my current favorites. But the red circle should not look too similar to the logo of the publishing company. Maybe a red square would look better?

The text of logo below looks very good, but for me the ‘fn’ does not fit so well. Maybe it would look better with a chart instead?
