Examining the rules and regulations that entice investors and keep financial marketing flowing



The global economy is built on a foundation of investor trust. Like it or not, this trust is what keeps the work’s financial markets humming. Beneath this trust lays fundamental economic principles that have influenced trading for decades, and even centuries. An expert in financial market regulations and data analysis, Chinmay Jain, PhD, Assistant Professor in the Faculty of Business and Information Technology, studies which economic rules will positively impact the market. His research helps regulatory bodies formulate rules which make financial markets more attractive to investors.

Dr. Jain’s research also examines the impact of short sellers in the equity markets, and the effect of short selling restrictions placed by regulators in the aftermath of the financial crisis. His most recent work investigates the role of short sellers in the financial market in the after-hours on earnings announcement days.

With a penchant for applied math, Dr. Jain earned his Bachelor of Technology in Industrial Engineering from the India Institute of Technology in Kharagpur, India in 2004. He spent three years as a software engineer with GlobalLogic India in Noida, India, and Qwest Communications Inc., in Bangalore, India, before moving to the United States. The role of rapidly advancing technology in increasing the complexity of financial markets, spurred his interest in earning his Doctorate in Finance from the University of Memphis, in Tennessee in 2012. That same year he received The Financial Review Best Paper Award for his co-authored research paper entitled: Shot Selling: The Impact of SEC Rule 201 of 2010.

Bringing international expertise in understanding market microstructures and trading rules to the UOIT classroom, Dr. Jain motivates his students participate in team challenges including the CFA Institute Research Challenge which promotes best practices in equity research among future analysts.

Short Selling: The Impact of SEC Rule 201 of 2010 The Financial Review


Despite its sizeable compliance costs, this research shows no clear benefits of SEC Rule 201 in ensuring fair valuations and price stability, promoting higher liquidity and execution quality, or preventing a sudden flash crash or prolonged market crises. Daily and intraday analysis of data both before and after Rule 201 finds that short sellers are naturally more active before the occurrence of negative returns, not after significant price declines.

Everything Old is New Again Regulation


The Securities and Exchange Commission’s new Rule 201 restricts the short selling of stocks after a 10 percent price decline, with the intention of preventing short selling from further driving down stock prices. However, empirical evidence from recent stock price declines suggests the rule is unnecessary.
