Matt publishes his newsletter Monday-Thursday, and a podcast on Fridays. It is a roundup of stories with high quality commentary on 2-4 stories, and a list of additional interesting articles at the bottom. He used to be an attorney with Goldman Sachs, giving him a good background for adding context to market corner cases people exploit, incentives of different parties involved in deals, legal perspective, etc.

Two of his main lines is "everything is securities fraud" and "everything might be insider trading", with probably 100+ examples of each over the years.
