>It is not a science. More of an art form.
Chuck,
The 'art form versus science' discussion is in just about every
published work on stock or futures trading.
My take is this:
If you can state that there is about an 82% correlation between IBM
and GENZ, and that you used a 'quick scan' to find these two as your
next 'pairs trade'... then we seem to be talking science rather than
'art form', eh?
Your Pal,
Phsst
