Neither the 1 year, 3 years or 5 years term have passed since your purchase. AAR can't be calculated until the stated term is completed.
"If it ain't broke, don't fix it". I wonder if when separating from Intuit that Quicken had to rebuild the software from scratch due to proprietary reasons and in doing so has made a ton of errors in it's haste to get it done? Hopefully everything is fixed when my 2017 subscription expires in September 2018.
Dennis, perhaps your original situation was that somehow a share price of zero got into the price history on or just before 1/1/2018. You might want to check that before deleting and re-entering everything if you see this problem again.Rsta, if you have held the securities for less than the analysis period or if the analysis period is less than one year (YTD for example) the average annual return (IRR) can be calculated but it will give confusing results. This is especially true for securities that have varying share prices. In previous versions of Quicken, it would display N/A in the Investing/Portfolio views in this case. In QWin 2018, they chose to display the correctly calculated but confusing number instead. To get a better feel for what is going on, I suggest you experiment with the Investment Performance report (Reports/Investing/Investment Performance) which shows the balances and cash flows that contribute to the IRR calculations.I think you will find that if you plug the same values into Excel's XIRR function, you will get identical or nearly idnentical results.
