Technological developments in securities markets, most notably high frequency trading, have fundamentally changed the structure and nature of trading over the past fifty years. Policymakers, both domestically and abroad, now face many new challenges influencing the secondary market's effectiveness as a generator of economic growth and stability. Faced with these rapid structural changes, many are quick to denounce high frequency trading as opportunistic and parasitic. This article, however,

This article proposes a regulatory model aimed at maximizing high frequency trading's beneficial effects on secondary market functions. The model's foundation, however, requires information. By analyzing more data on how high frequency traders interact with markets, regulators can assess the viability and scope of other potentially worthwhile measures targeting more general market threats. Likewise, regulators can determine who is in the best position to bear supervisory responsibility for particular trading activities: agencies, exchanges, traders, or some combination thereof. Crucially, the model also calls on regulators to share information on a global scale: trading no longer only affects a single exchange, a single asset class, or even a single country. By sharing information, regulators can enact more informed regulations, stabilize secondary markets, and minimize regulatory arbitrage. In short, high frequency trading can be a force for good, but a principled and coordinated effort is needed to ensure it fulfills that potential.
