Chris Bloomstran recently questioned Ark Investment’s open-sourced research model on Twitter which resulted in him engaging with Ark analyst Brett Winton in a very public forum about a certain electric car company.

For anyone who witnessed the exchange, it spoke volumes about the difference between what passes for analysis today and the kind of rigour displayed by those who have honed their craft in times of far more scrutiny.

Chris and Grant discuss that exchange, the company in question, what Chris learned from the discussion and how it recalls similar experiences he witnessed during the dotcom bubble of the late-1990s.

This is a discussion all value investors will relish but, given the euphoria surrounding markets today, it serves as an invaluable reality check for those believing they only go in one direction.
