Here's a link to a thread-starter that I put up today at the SWR Research Group board:
The title of the thread is "Revolution." It is Andrew Smithers who has said that we are about to experience a "revolution" in how people think about investing strategies.
The purpose of the thread is to make people aware of a recent "Editor's Column" by Rob Arnott, editor of the Financial Analyst's Journal. The column is titled "Whither Finance Theory?" and it takes some strong stands on some controversial questions. I see it as the opening shot in the Revolution predicted by Smithers. There's a PDF link to the Arnott piece at the linked thread.
