Traditional IRA Conversion to Roth IRA > Cost Basis
This is the first year I have performed the above transaction. As I understand, the process in Quicken is to "Remove Shares" from the Traditional IRA account and to "Add Shares" to the Roth IRA account. The conversion is within the same investment (a Vanguard mutual fund) and did not involve a sell/buy transaction. After completing the transaction I noticed that the "Gain/Loss (%)" column in the Investing Summary page shows a lower gain than prior to the conversion. I expected the cost basis to remain the same. Does Quicken change the cost basis of the original investments to the conversion date? If so, is there a way to avoid this cost basis change?
