I've never really trusted Quicken's performance calculation as they always looked way off in the past. But really need to use them now and all the numbers are very obviously way off on their face value.
I download all transaction religiously and reconcile them monthly and have been for many years, so I know the ledgers are right.
Examples:
1) One brokerage account shows negative returns for all periods (1, 3, and 5 years), but the graph shows a balance higher than cost basis and having archived it within last 5 years or less. And that's not even counting dividends and interest. So obviously it can't be right.
2) Several accounts show exactly the same % returns, down to 2 digits after decimal, for all periods, yet have been there long enough to cover all periods and more. That's not possible as a coincidence.
3) An fairly new account which only earned me interest and had no losses, ever, is showing as 93.36% annual loss. lol.
4) Opening the individual security window shows the exact same performance for all periods, even for shares owned for much longer that any of them.
It's like it's been [Removed-Language] or something, LOL.
What is going on and is there a fix?
Needless to say, I've run file repair many times throughout my use already.
