David Shapiro on Discovery's 'blackhole', SA Inc sell off and the missing prosecution

This week on Rational Radio David Shapiro spends a lot of his time searching for answers to Discovery's massive sell off which has seen the stock fall to around R100 a share. There's talk of an analyst and a gaping R15bn hole, while National Health Insurance also finds itself amongst a bag full of potential reasons. SA Inc also experienced a marked sell-off recently, with David searching for a reason to buy. While Steinhoff's investor presentation and the topic of Markus Jooste also come up for discussion.
