Is a shame that it seems so many people on this board are here for nothing other than to refute the validity of other peoples questions and/or beliefs. There is no question that underlying economic influences govern the markets so the question is not whether or not it is a valid pursuit to try and understand them but rather a question of how to pursue this knowledge. There are many primers on basic economics which can give you an understanding, BUT if you are going to really understand the real time influences that affect markets day to day you will eventually have to toss out the theoreticals and focus on the real interactions of money flows. The best single resource for data relating to this can be found at the Federal reserve Websites, particularly the St. Louis Fed and the New York Fed. Good Luck!
