In this module we explore how the financial markets operate; we look closely at how different types of instruments (investment products) such as stocks, bonds, mutual funds, and exchange traded funds (ETFs) function; and (3) explore some of the basic uses for such instruments. This module is open to all students; however, it is designed for high school students who intend to go on to college and want to develop a solid core understanding of this extremely important business topic. Students in Module I will take several short-online multiple choice quizzes and also participate in a weekly online discuss group. Students can enroll in Module I and not be required to take subsequent modules. This is a particularly beneficial option for students ages 12-15 who want to develop a basic understanding of how the stock and financial markets operate.
