This study is the first to apply human beings' preferred diurnal rhythm, that is, morningness or eveningness, to the field of behavioural finance. Employing proprietary stock trading data from a leading retail brokerage house in Australia, we classify retail investors into M-types (‘early birds’) and E-types (‘night owls’) based on the time of their order submission. Demographic differences between the two groups (M-types or E-types) are found to be weak. We provide robust evidence that M-type investors are distinctively different from E-type investors in their proneness to stock market behavioural biases. We find that M-type investors trade more frequently and have a stronger preference for stock market speculation.
