Information Issues on Wall Street 2.0
Billions of dollars have flooded new online marketplaces for trading private company stock. These marketplaces stand poised to become important, lasting features of the private company world as they provide a central meeting place for buyers and sellers and potentially increase the liquidity of private company stock. Increased liquidity is particularly important to investors in start-up companies, as these companies have faced longer periods of time before going public or being acquired. The new marketplaces also raise significant information issues, however, that threaten their legitimacy and efficiency. This Article is the first to examine these information issues — lack of information, asymmetric information, conflicts of interest, and insider trading — as well as possible solutions that would allow the markets to continue to evolve while promoting their integrity and investor protection goals. Specifically, the Article proposes establishing a minimum information requirement for secondary trading in private company stock and reexamining the thresholds for accredited investor status in order to ensure that market participants can fend for themselves without additional protections. The Article also examines potential responses to insider trading in these markets, arguing that a case exists for the SEC to take action in the private market context, since harm may be cognizable and the arguments for regulating insider trading are as strong in the private market arena as in the public.
Overvalued Equity and the Case for an Asymmetric Insider Trading Regime
The forty-year debate over whether insider trading should be regulated has generally proceeded in all-or-nothing terms: Either all insider trading should be permitted (subject only to private restrictions imposed by issuers themselves), or none should. This Article argues for an asymmetric insider trading policy under which insider trading that decreases the price of an overvalued stock is generally permitted, but insider trading that increases the price of an undervalued stock is generally prohibited. Concluding that the net investor benefits of price-decreasing insider trading exceed those of price-enhancing insider trading, the Article argues that an asymmetric insider trading regime likely represents the bargain that shareholders and corporate managers would strike if they were legally and practically able to negotiate an insider trading policy. Current insider trading doctrine would permit regulators to impose such an asymmetric insider trading policy as the default rule.
Empirical evidence on the impact of European insider trading regulations
We evaluate in this artic1e the impact of the regulations on insider trading introduced between 1988 and 1994 on ten European securities markets. We consider the temporal behavior and the distributions of abnormal returns, market models, and time series models of time-varying mean returns and volatility, and conclude that the bulk of the evidence suggests that these regulationsi have had little (if any) impact on the series of returns of the markets in our sample.
