We like your style and the concept you provided. #321, #322, #294 and #320 (in that order) are good. Still they are a bit abstract while we want the logo to make an immediate connection with finance. Can you please try experimenting around the original concepts and try putting more financial context in them while keeping the current style and feeling.
In addition we have some more general feedback: - Make the font more light (thinner) and wider (wider letters, not condensed). It should feel modern and vibrant. - Use all-caps. The "i" should be without the dot. - The 10-K should have a hyphen
Thank you for your feedback. Since the symbol looks abstract, i add something directly to show about finance. Also changed the font style as your mentioned.
