Duncan Artus on Allan Gray's poor performance, the Sasol disaster and buying Naspers

Once in a while, the country's biggest investors lift the veil on their strategy, sharing ideas on how they intend applying the hundreds of billions entrusted to them. That's exactly what Allan Gray director and portfolio manager Duncan Artus did for us in the latest episode of Rational Radio where he discusses why the company is such a big investor in Naspers, and how its Sasol shareholding knocked a hefty 4% off the total return of its biggest unit trust last year. And he answers the criticism about the performance of Allan Gray and its global cousin Orbis over the past year. Fascinating insights from one of SA's most thoughtful money managers. - Alec Hogg
