It's a Fidelity stock based Mutual fund. I've owned it for about 30 months. I've had at least 60 transactions since then. The decimal issue goes all the way back to the first transaction.
He had indicated that there wasn't a split.
This appears to be a case where the OP is entering the transactions manually and has not entered the split yet but the price history is coming from Quicken's quote provider, which has caused a hidden split in the price history. Perhaps there have been no transactions since the split on 5/11 or 8/10, depending on the fund.How should he handle this, apart from entering the split on the appropriate date?
