First of all, warn your friends that there is no "Fill it, shut it, forget it" in speculative instruments like share bazaar. That happens only in bank/post office FDs.
Whatever investments you invest in, whether the equities directly or mutual funds, you have to manage it, generally EOD. Also, you have to set some kind of stoploss for it. It is not risk free.
Then check what kind of returns he has in mind. Then moderate his expectations. Psychology is the greater part of participating in the markets.
