Hi,
You can now download the history of each portfolio as a csv file.
The data is updated daily.
The files are not yet linked from the main site, so you need to build the URL yourselves for the time being.
It is
http://www.superstockpicker.com/<Name of the portfolio> history.csv
As an example, here is the Low PEG Ratio history file URL:
http://www.superstockpicker.com/Low PEG Ratio history.csvI hope this will be useful.
