““In the Middle Ages the outbreak of a plague caused people to raise their eyes towards heaven, and pray to God to forgive them for their sins. Today when people hear of some deadly new epidemic, they reach for their mobile phones and call their brokers. For the stock exchange, even an epidemic is a business opportunity. If enough new ventures succeed, people’s trust in the future increases, credit expands, interest rates fall, entrepreneurs can raise money more easily and the economy grows.””
