I have a very small discrepancy between what Quicken says is my total number of shares of a T Rowe Price mutual fund, and what I actually have (we're only talking about a few thousandsths of a share, here). What's odd is that, when I go to the mutual fund's web site, my account there is correct, and not the same as what Quicken says it is. I had figured that whatever shows up on the web site is also what Quicken is going to think my actual holdings are.
As it's such a small difference (a matter of a few pennies), it's obviously not important, but I wondered why this was happening, and whether these discrepancies are common or rare. T Rowe Price is the only case where I've seen a discrepancy, among my own holdings. I've been tempted not to even check whether Quicken has downloaded the correct amounts when I get paper statements in the mail, but now I feel obliged to check to make sure it's not bringing in significantly faulty information.
