I once witnessed a role-play exercise at a financial planning conference that attempted to answer, in amateur dramatic form, the question 'what must an adviser do when faced with a client who insists on buying a rubbish investment?'.
The answer, arrived at after an agonisingly long theatrical performance, was to get the client to sign a waiver first before the adviser would transact the crap and pocket a commission.
It wasn't just the acting that stunk in this scenario - there was something whiffy about the plot too.
Everyone's a critic, of course, but why, I thought, couldn't this story end with the adviser booting the client out the door while yelling "and take your 'prospectus' with you".
This little drama played out in ancient pre-regulatory times so maybe you could forgive (although I didn't) the writers for concluding with the waiver-before-transaction angle.
