Today the AIM blog was linked to The Research Puzzle Blog - research puzzle pix. It's a digest of interesting investment items from across the landscape that comes out three times a week. Tom Brakke is the editor of the blog and he used to teach in the applied finance program at the University of Minnesota's Carlson School. He is interested in research being done by the various student-managed investment funds.
His original site is the research puzzle, where he writes essays about once a week on the "how" of investments: how investment decisions are made and how the business operates. For instance, one useful article that Mr. Brakke recommends is about unpegged valuations (PEG ratios). He indicates that he has a number of professors and students that read my site and invites the AIM student to be among them.
