Bodie, Kane, and Marcus' "Investments" sets the standard for graduate/MBA investments textbooks. It blends practical and theoretical coverage, while maintaining an appropriate rigor and a clear writing style. Its unifying theme is that security markets are nearly efficient, meaning that most securities are priced appropriately given their risk and return attributes. The text places greater emphasis on asset allocation and offers a much broader and deeper treatment of futures, options, and other derivative security markets than most investment texts. It is also the only graduate "Investments" text to offer an online homework management system, 'McGraw-Hill's Connect Finance'.
