The National Investment Club Conference 2008 takes place in London on 15th November 2008 in association with Proshare Clubs and The World Money Show, which you might find useful. It will be a good opportunity to meet other clubs from London and across the UK and learn more about investing.
There will be seminars and presentations covering everything from the legalities of setting up an investment club and managing club accounts, to stock selection techniques and strategies.
The event is FREE to attend.
