But technology has not solved many of the long-time challenges that markets pose for institutional investors like funds, including the ability to trade large blocks of stock in the most efficient manner possible. And advances in technology have created new challenges: fragmented markets, for example, that have resulted in less displayed liquidity and a smaller average execution size.
Focus on Practices and Market Structure
It is critical that regulators address these challenges and examine whether the rules governing the markets have kept pace with the significant changes in technology and trading practices. This examination should be broad and should focus on a wide variety of practices that could potentially harm investors, such as widespread order cancellations, “quote stuffing,” and the practice of providing liquidity rebates and other incentives to route orders to particular venues.
Inevitably, an examination of these practices will raise the debate over “high-frequency trading.”
High-frequency trading has become a catchphrase that covers a wide range of activities and practices—most of them legitimate—and that too often obscures the debate rather than clarifying it. High frequency trading arguably brings several benefits to the securities markets in general and to investors, providing liquidity and tightening spreads.
But regulators do need to concentrate on practices by market participants—including high-frequency traders—that are abusive, including strategies designed to detect the trading of large blocks of securities by mutual funds so that traders can front-run those blocks.
All trading venues and market participants, no matter how technologically savvy, should compete on the basis of innovation, differentiation of services, and the value their model of trading presents to investors. The securities markets and the regulations that govern those markets must operate in the interests of investors. “Man vs. machine” can morph into “man and machine” when regulators have the information they need and modern regulations in place to reflect our modern markets, ensuring an efficient, fair and transparent market structure for all participants.
