This book underscores the complexity of the equity markets, the challenges they face, and the fact that they are still a work in process. Three interacting forces drive market change: competition, technology change, and regulatory change. The markets have one major objective in particular to achieve: the delivery of accurate price discovery for both traders and the broader market. Are we getting it? Are competition, technology, and regulation acting together to improve market quality, or are they adding to the complexity of the markets and making accurate price discovery harder to achieve? The difficulty of addressing these issues and reaching a consensus regarding public policy is reflected in the diverse opinions expressed in this book. From an institutional perspective, the volume's contributors highlight the interconnectedness of all aspects of the internal and external environment within which exchange organizations act.
