Dave R. is correct to call out the timing as a source of the issue. Just to add some additional background, I work in the financial services industry and a component part of my team's work is to ingest prices from 200+ mutual fund companies, covering tens of thousands of mutual fund prices.
The best practice in the mutual fund industry calls for prices to be available by 9:00 PM Eastern Time. However, in my experience, several factors can influence how quickly prices are calculated: (1) market volatility for the day can really mess with prices for equity funds, (2) prices are often delayed during dividend/cap gain payment season, the worst is in December, but can also affect price delivery in March, June, and September, (3) industry-wide issues, there are only a handful of companies that do fund accounting, so when one of them has an issue, it can cause problems across the industry, (4) fund companies often publish corrected prices on the same day, it's possible that Alphavantage has a different price than Yahoo, for example, depending on how quickly they (or their vendor) is ingesting updated prices. My cron job for updating prices doesn't run until 5:00 AM. There are additional reasons for this, but I wouldn't set up an automated price update until 2:00 AM Eastern at the earliest for the best chance of getting the most up-to-date mutual fund prices.
