Professor Lasfer will examine the reasons why insiders trade, and the significant role private information plays in insider trading, as well as look at portfolio changes due to these activities.

Meziane Lasfer is Professor of Finance at Cass Business School (Go to Meziane Lasfer's Cass Experts entry).

Professor Lasfer will examine the reasons why insiders trade, and the significant role private information plays in insider trading, as well as look at portfolio changes due to these activities.

He will also consider the legal issues underlying insider trading, specifically the implications of trading before earnings and other price-sensitive information and compare the differences between US and UK laws, and explore statutory rules and enforcements. The question of when do insiders trade will also be discussed, with examples from the vast amount of corporate news announcements and how this affects the decision to trade or not to trade before positive news or negative news. These decisions are often conditional on the information content of the disclosure (proxied by stock price reaction), and Professor Lasfer provides examples and empirical evidence on this strategic trading of insiders.
