Quicken does not guarantee accuracy of downloaded investment data. I have been seeing duplicate companies names and amounts. It has taken weeks to get recognition of the problems and finally determine they could only fix the problem by me modifying the data manually myself. When companies restructure their corporation the brokerage account and Quicken fail to accurately transition and update Quicken downloads. The office of the Vice President of Customer Service has given up on the issue with no promise to fix the date problem.
