While keeping the seriousness of a stock news website, I incorporated modern neon variations of green and blue as a gradient in the stock chart behind the text logo.
Nothing is edgier than a bold and simple font. That's why I've used Helvetica Bold in the logo.
Below the logo, I created a simple layout with modern purple, gray and green to visualize how your logo will sit on a web page. Since purple is a color representing wealth and popular one lately, I decided to put it into the layout just to provoke some ideas.
