Check out DRIP, if my impression is correct that you want something that is relatively lower in risk, and longer term. Whatever little I know about stocks is from my brother, who has taken this on obsessively as a new HOBBY. He's my younger brother, and doctor by trade. He trades way higher in frequency than someone like me, but he's given me a few good tips as someone who's scared of stocks.
Drip = dividend re investment plan. You'll find them with long standing blue chip stocks, not newer companies as they need to reinvest into themselves more. Companies like ATT and Verizon offer 6%, AFAIK. As a Drip, that 6% goes back into buying more of that stock (and with no transaction fee either).
So, he gave me a scenario, for instance. I know 12k is a lot of money, but you'll get the point. Say that you have 12k in IRA. Say you're stupid enough to put all of that into a Drip. Let's say you retire in 33 years. The IRA means 0% tax liability, ok.
Even assuming that the stock NEVER INCREASES IN VALUE (extremely unlikely), after 33 years, your 12k has now become 91.5k.
Well, I may look into throwing money into Drips soon, as I trust my brother. He did say it's key to start early with those.
