David Shapiro: Praising Naspers, blasting Sasol, Old Mutual, Aspen

South Africa's favourite market commentator, Sasfin Securities deputy chairman David Shapiro, was at his best in this week's episode of Rational Radio. He is forthright in his appreciation for the role that Naspers has played in bolstering SA retirement portfolios (his own included) and delighted to see the strong debut of its offshoot Prosus on Amsterdam's Euronext market. But not that enamoured with the collapsing share prices of Sasol, Aspen and Old Mutual - all of whose misery appears to have been self-induced.
