In the Balance examines the recent sharp falls in the global markets. Ed Butler asks why volatility is back in the financial markets - after years of relative calm. Ed is joined by one of the world's leading experts in algorithmic computerised trading as well as a fund manager with more than 30 years experience of watching the market highs and lows. But is this time different - is computer driven trading at least partly to blame for an increase in volatility? Should we be in fear of the machines?
