Toronto, Feb. 12, 2013 - CFA Society Toronto and Hillsdale Investment Management have announced that William J. McNally, Andriy Shkilko and Brian F. Smith of Laurier School of Business & Economics have won the 2012 Canadian Investment Research Award for their paper “Do Brokers of Insiders Tip Other Clients?”

The Toronto CFA Society and Hillsdale Canadian Investment Research Award is open to global researchers conducting research related to Canadian capital markets, including both academics (professors and students) and practitioners. Submissions are judged on the potential contribution of their research to Canadian capital markets. CFA Society Toronto and Hillsdale Investment Management offer this prestigious award annually to encourage high-quality research on investment management. 

The winning research paper, “Do Brokers of Insiders Tip Other Clients?” was selected by a panel of judges from among nine submissions. CFA Society Toronto and Hillsdale Investment Management will award a $10,000 CAD prize to the winners tomorrow at the 3rd Annual Award Reception. 

"One would like to believe there is no grey in the application of regulations governing insider trading in Canada. This paper raises important questions about the obligations of all fiduciaries as well as about the ever changing role of technology in the distribution of insider information. Hillsdale is pleased to support the annual Toronto CFA Society and Hillsdale Research Award and to reward professors McNally, Shkilko and Smith of Wilfrid Laurier University for their meticulous work." said Chris Guthrie, CFA, President and CEO, Hillsdale Investment Management.

Laurier researchers used a unique subset of TSX data obtained with the permission of IIROC (the Investment Industry Regulatory Organization of Canada). Insiders are required to disclose their status to their brokers who, in turn, are required to flag insider orders on the TSX trading system. The unique TSX dataset has orders and trades for the period from October 2004 to December 2006 with the insider flag. Since the data also includes a broker ID for each order, Laurier researchers were able to track broker activity around insider trades. 

“Brokers of insiders have a bigger market share after an insider trade,” said Professor McNally. “They handle more agency trades in the same direction as the insider compared to the average for the other (active) brokers.  In addition, their market share of principal account trading also increases after the insider trade. This is the pattern that you would expect to see if the brokers of insiders tip their other clients about the insider trade,” he said.  “We are concerned about these results, because it suggests that there might be an unfair playing field. Some traders are receiving valuable information before the rest of the market. This lack of fairness may lead to a reduction in liquidity, which is bad for the entire market.”

Key findings:

The market share of the insider’s broker is about the same as the market share of the average competitive broker prior to an insider trade and then rises sharply on the day of the insider trade.

The abnormal market share (the difference between the broker’s share of client trades and the share of the average broker) jumps from 0.7% on the day before to 3.8% on the day of the insider purchase. Similarly for insider sales, the share rises from 0.9% before to 4.5% on the day of the sale. Furthermore, the market shares spike in the half-hour interval immediately surrounding the insider trades.

Independent brokers experience significantly larger market share increases than brokers affiliated with banks. Evidence of tipping is stronger in broker handling of shares of smaller companies. This is consistent with greater information asymmetry between the insiders and outsiders in smaller companies.

The insider’s broker’s market share of principal trading doubles on the day of the insider trade for both insider purchases and sales. This suggests brokers trade on their own account or that they tip other employees in the firm.
