Rules Ira

Question: If you own a stock in a IRA, is there a rule that it should be held for a year before selling?
Or has there in the past been a rule that IRA investments should be held for a year before being able to sell or change to another stock(or investment)?
Please help!
Answer: Nothing in law. I know some mutual funds say they have to be held for at least X amount of time or they are subject to penalty.
But you can trade actively within an IRA if you choose to do so.
