I came to realize that Seeking Alpha is unable to post accurate closing prices on a timely basis for ALL mutual funds. Thus, if you include mutual funds in your portfolio, the values will be inaccurate. I have pointed this out to Seeking Alpha and their developer, but they are unable to correct this problem.
Tip for consumers: That they are unable to reflect accurate data for any mutual funds. Their customer service team repeatedly assured be that the problem would be corrected, but never had.
