It would be amazing if you could set a pool of your money to follow/mimic a portfolio of another user who has agreed (perhaps a ‘tipster’ or perhaps just a friend who you think will do better than you). The moment they make a trade all the money following them would also make the same trade. This has never been possible before because charges and commissions would make it unfeasible.
This could do away with dreaded fund management charges as there are thousands of people who are at least as good as professional fund managers who would delight at the prospect of helping others for free.
You could have a searchable list of ‘open’ portfolios so users can decide whose they want to follow based on their average returns, user trust rating, type of companies the portfolio is holding and has traded in the past, length of time the portfolio has been going etc.
Just my 2p’s worth
