Thanks - you jogged my memory. I did take a basic econometrics course prior to the seminar on contemporary published papers. I can't believe that textbook you linked is almost $200. I remember textbooks being close to $100 in my day - a lot of inflation in a quarter century. Anyway, you reminded me that I still have some books from as far back as college.
While even my basic econometric text is way too complicated (filled with calculus & matrix algebra & statistics), I did locate an overview paperback that provides a more intuitive feel with just the bare minimum notations and technical details (Peter Kennedy's A Guide to Econometrics published by MIT Press in 1985). Although even with that book, a richer math background and more solid economics/finance basics would make a huge difference.
I have never worked in the financial markets. I am just more comfortable/familiar with the stocks on NASDAQ than the other exchanges so would be able to discuss them with a modicum of intelligence.
