For what it's worth - I was a floor trader (dealer) on the JSE from 1967 to 1976. We saw a massive boom and bust in 1969. There was a bounce but then prices settled at VERY low levels. e.g. SAB was below 100c - albeit after a split. Prices generally (of non-mining shares) took some 10 years to recover. But the main problem for 4 or 5 years was the lack of trade. In April/May 1969 I could effect hundreds of trades in a day. In 1974 that had fallen to maybe 20 trades in a day and price movements were tiny. It's a bit different now. The contractual savings industry was in its infancy then: it's huge now. There were no SSFs, Warrants, CFDs etc. etc. then. Communication with the world was still very slow: now it's instantaneous. There were very few "day traders" operating on the JSE. And other differences - many of which have contributed to the speed and extent of recent declines. But what hasn't changed is human nature. When confidence is damaged it takes time to be restored: the greater the damage, the longer the recovery. And the damage globally is huge right now.
