What is this data?

[Ernie Bonugli <ebonugli@xxxxxxxx>]

David Folster, for who I don't have a valid address, had S&P 500 data
going   back  in time a long ways.  I remember he used it to
qualify/disqualify OB.  Multiple people participated on that
project.

My  question  is  whether anyone knows how that data was put
together,  ie  how  were  the contracts adjusted to form the
continuous   file?    If  anyone knows anything about it please
email me.

Also if someone knows the current email for David Folster, would you
shoot it over my way?


thanks,
Ernie
