Actually the Average Annual Return in the Investing Portfolio views is an Internal Rate of Return (IRR) calculation based on your holdings of the security. QWin 2018 shows the result of this calculation even if you did not have any shares at the start of the period. The calculation is valid but misleading if you did not hold the security for the whole period.In earlier versions of Quicken, the Investing Portfolio views would display N/A if you did not hold a security at the beginning of the time period.
