Nothing in the rules of a standard Roth IRA prevents you from buying and selling stocks the same day. So, in that limited sense, you can perform day to day operations on a Roth IRA. However, the IRS prohibits many forms of speculative and high-risk trading in retirement accounts. Depending on your retirement plans, you can have all of the investments in a Roth IRA listed above, as long as the Roth IRA holder offers them.
So, whether you already have a Roth IRA or are considering the option, it's wise to know the rules, regulations, and restrictions of investing in a Roth IRA. The main rule that blocks the daily operations of a Roth IRA is that Roth IRAs are cash accounts and do not allow margin to be used to help buy securities. Like any other retirement account, a Roth IRA has flexible limits on what you can hold as investment assets within your Roth IRA, including stocks, bonds, ETFs, bank accounts, certificates of deposit, mutual funds, mixed-asset funds, and alternatives to cash. While the fact that you can't trade on margin in a Roth IRA excludes day trading, that doesn't mean that all active operations in a Roth IRA are ruled out.
