I trade in my 401. I am older so it gives me access to profits. You just don't do super long hold. That said held srmx 3 years and made some serious profit last month.
In your own personal IRA, you can buy and sell penny stocks often. No capital gains taxes due as long as the proceeds stay in the IRA. A small portion of the account could be used as a lotto or fun play. Or most of it, if so desired. Fortune favors ....
