Abstract

Although financial dogma attributes comovement to common factors in security returns, scholars have struggled to connect those common factors to news about earnings. Instead, disruptions in the flow of information explain perhaps twothirds of comovement. Over time, barriers to the transmission of information dissipate, and market efficiency correspondingly improves. From comovement and the contrast between microscopic and macroscopic phenomena, this chapter extracts a physically inspired approach to financial time. This chapter then explores intertemporal and consumption-based theories of asset pricing. Those subjects lead ultimately to multifractality and the fractal market hypothesis.
