When I create a duplicate of a portfolio, I get different results on the duplicate and the original portfolio.
In this link, you can see the NASDAQ 100 Hedged portfolio and the Duplicate Portfolio performance. Both screen shots were within a few minutes of each other.
Update: This occurred several times today as I was trying to understand what’s happening. I just ran it again and the problem went away. Rather confusing. any ideas? Possible interday data may have caused a problem?
