This is a great video advocating for passive (or index fund) investing. The film is made for a UK audience but is applicable to anyone who invests anywhere.
While the film was funded by an investment management firm, it is accurate and not misleading. The points they make are correct and are borne out by the academic research.
Finally it is worth watching just because you get to see some of the big names in finance - Jack Bogle, Ken French, David Booth (Chicago B School named for him), and of course Bill Sharpe - the guy who developed the CAPM and got the Nobel.
