I recently converted a traditional IRA to a Roth IRA. A broker is the current custodian of this account. I have some shares of stock that I have purchased through a couple of different DRIP programs, and also some shares of mutual funds I've purchased through the years through no-load companies. All of these securities are held in regular, taxable accounts. I am trying to determine if it is possible to transfer any of these securities into my newly converted Roth. Is my only option to liquidate these accounts and transfer the cash to the Roth?

Only cash can be contributed to an IRA, roth or traditional (unless it's a rollover)
