Understanding Investments helps you do just that. In 24 lectures, it introduces the fundamentals of investing to those new to the subject while broadening and deepening the knowledge of more experienced investors. Taught by Professor Connel Fullenkamp, an award-winning educator from Duke University who regularly consults in the world of international finance, these lectures clearly explain the various kinds of financial markets, the different kinds of investments available to you, and the pros and cons of each. Even more important: The course shows you how to evaluate each of these in terms of your own financial situation. See Part 1 here and Part 3 here.
