I'm starting a new Roth IRA with a discount broker. I'm a bit confused about owning and tading stocks within your IRA. Let's say I bought 100 shares of company X for $20 each. That's my total contribution for a year. In six months, those shares are $30 and I want to sell them. Now my IRA has $3000, can I keep it all there or do I have to move $1000 of it elsewhere?
