I have encountered a problem with the Quicken Update function on the Investment Portfolio screen. On Friday, July 4th, I updated my entire portfolio following the market close. All of my investments updated to reflect the correct closing market quote/price for the day. The sole exception was the closing market quote for the Vanguard 500 Index Fund (Admiral Shares). I hold shares of this mutual fund in (3) different accounts and all (3) are significantly misstated. Please note that I hold several other Vanguard mutual funds that are unaffected by the above issue. Any words of wisdom? Thank you.
