To every thing there is a season. In the area of securities regulation in the United States, it is the season for expansion. This article shows why such expansion should not involve use of the core issuer disclosure, fraud, and insider trading laws to reduce information asymmetry in the stock market in the name of investor protection. I argue that any expansion of these laws focused on this secondary market should therefore be justified by distinct concerns (namely, efficiency ones). Moreover, any push to better serve and protect investors should be focused on other areas of securities law (such as those relating to the structure of securities markets) or other markets (such as the market for investment management).
