Want to make an almost sure bet on where stocks are going on a particular day? You could start by measuring the length of traders' commutes. At least that's what a recently published paper by two researchers from the University of Economics and Technology in Ankara, Turkey, shows.
The paper by Serkan Imisiker and Bedri Kamil Onur Tas has looked at the relationship between the morning rush hour traffic in London and the returns of the FTSE 100 index between 2006 and 2014. It found a "significantly positive" relationship between the average speed of vehicles at rush hour and market returns.
