The question is too vague, IMO :) I'll try though. Yes, flex
can help you show a stock list.
Where is the data coming from? From a HTTP interface? A web
service? You'll need to look into HttpService and WebService
classes respectively on how to get data.
How do you want to display this data? As a list? Maybe you
want to look into DataGrid or other list based components.
Do you want/need to show trends? Flex Charting is what would
help you chart these trends?
Or are you looking for some other info?
