We will be having a discussion on power laws. See here for paper.
In previous sessions, we reviewed Mandelbrot’s market model, which postulates that a power law governs returns rather than a Gaussian process. The paper below explores how power laws arise so frequently in nature. From the abstract:
“When the probability of measuring a particular value of some quantity varies inversely as a power of that value, the quantity is said to follow a power law, also known variously as Zipf’s law or the Pareto distribution. Power laws appear widely in physics, biology, earth and planetary sciences, economics and finance, computer science, demography and the social sciences. For instance, the distributions of the sizes of cities, earthquakes, solar flares, moon craters, wars and people’s personal fortunes all appear to follow power laws. The origin of power-law behaviour has been a topic of debate in the scientific community for more than a century. Here we review some of the empirical evidence for the existence of power-law forms and the theories proposed to explain them.”

We will be having a discussion on an analysis of the size premium of small-cap and micro-cap stocks. See here for paper.
Yes, that is the actual title of the paper. And it actually has some meaningful, interesting results.
From the abstract:
“The size premium has been challenged along many fronts: it has a weak historical record, varies significantly over time, in particular weakening after its discovery in the early 1980s, is concentrated among micro-cap stocks, predominantly resides in January, is not present for measures of size that do not rely on market prices, is weak internationally, and is subsumed by proxies for illiquidity. We find, however, that these challenges are dismantled when controlling for the quality, or the inverse “junk”, of a firm. A significant size premium emerges, which is stable through time.”
