I suggest you revisit the portfolio section of Yahoo Finance. Funny things are happening there.
One case: Funds are calculated and reported to 2 decimal places but for fund VGHCX the calculation and reporting is to 6 decimal places.
In another case calculated numbers are reported as NMN.
In the Options Portfolio the extension of daily activity is no longer printed.
In the summary of all portfolios the short titles take half the page.
