As I write the overall market is taking another hammering with the US Dow Jones index down nearly 1,000 at one stage, yet again. My theory is that stocks up to February stocks were being driven higher by various factors - accelerating technological change, globalisation and rising global wealth.
This was great until the whole thing was hit by an exocet missile in the form of the coronavirus. It took a while to realise that the fact that the virus is much less deadly than says the Sars virus made it a much greater threat to the global economy.
