Throughout the week over at Securities Docket I highlight the most interesting columns and blog posts from around the web on the subjects of SEC enforcement and securities litigation. Here is a digest of my picks for the week ending January 27.

Are the feds overdoing insider trading prosecutions?
Prof. Stephen Bainbridge, ProfessorBainbridge.com

I am not one of those who thinks insider trading out to be legalized. To the contrary, I have defended a prohibition of insider trading–if not the precise prohibition established by current law–as a necessary way of protecting corporate property rights in information….The current emphasis on attacking hedge funds and expert networks, however, strikes me as having the potential to chill legitimate market analysis.

These changes, according to Feldman, have resulted in the five recent securities litigation trends he identifies in his article.

That will put even more pressure on defendants to cooperate with the government in the hope of receiving a reduced penalty.
