Surprised this was still out there (or already in your stockpile).
There are several online journals and weekly's with this title but none have the dot com (obviously).
Have not done any research for TM or anything of the sort. Maybe or maybe not an issue. Strong domain name with already an established base and traffic.
Many weekly news hours or shows or financial networks already use this as a segment of their broadcast. Would be a great tie in.
Providing there are no TM issue (God knows how the WIPO panelists see things), I would think low to mid xx,xxx.
You might consider starting your own blog with news and finance feeds and stock ticker streams for all markets worldwide. Could be a huge money maker for you as an affiliate program.
Good domain that needs to be developed. Potentially a steady stream of income for you improving your FinanceWeek!
