Once they figure out the degree of risk they can handle, they could start looking at the types of stocks to get there.
One idea might be to pick the top stocks from one or more mutual funds that fit the risk profile (after some research, of course). They may have some good ideas based on the products they or their friends have.
Have fun! The Richest Man in Babylon might be worth a look.
There's even a 4-minute video.
Thank you.
