Since this is a commercial site, you’ll need to consider the path on which you’re taking the visitor. Say he’s visiting your friend’s website for the first time.
- What is the most compelling thing he’s seeing and where he’s most likely going to go?
- Is he going to click anywhere at all, or are there too many distractions that’ll make him leave immediately?
- Are the most important elements of the site more compelling to look at than ones that aren’t as important?
Don’t assume visitors will go to portfolio/investing section first because it logically makes sense. Lead them there by hand, if anyone gets too bored or distracted, they’re probably going to leave. Right now there are many elements on the page that look very similar.
As far as actual design goes, you’re doing a good job. There are spots where text has to be made more visible due to background images and you’re doing that well. You’re also being very consistent which is great.
I’d work on responsivity a bit, specifically the menu. Since you have lots subcategories, I recommend doing something like www.livestream.com has, here’s a screen: http://prntscr.com/lel9xa or you can check their site and see it from on a small resolution, that’ll give you a better feel for what I have in mind.
