I have a table that lists the history of stock transaction (extract attached). I require assistance to find out how long I've held each stock for?
For example, I held AAP within the 12 stocks (fixed scalar) I held on 31/12/1999 and 7/1/2000. However it was not held in the portfolio of 14/1/2000. This would mean the hold period for this stock is two weeks (2 weeks). I require this calculation to go into a separate table.
Row 1 - '31-Dec-1999' 'AAP'
Row 13 - '07-Jan-2000' 'AAP'
Can someone please assist as to how i can go about implementing this?
