I just opened an IRA account on TDAmeritrade.com. I only put in several thousand dollars as a starter, just for exploring the interface.
I have never had an IRA account or even read much documentation about it yet. I previously already have an normal stock account with TDAmeritrade and are familiar with the basics.
My first dumb question is: what and how to buy stuff in the IRA account? Can I buy normal stocks? What else can I buy or is good to buy in an IRA?
Update: Thanks for all the kind replies and comments. I purchased a few shares of SPDR S&P 500 ETF.
