Price noise proves the key to high performing ‘bets against beta’ investment strategies
Peer-Reviewed Publication
Beta is a measure of an investment stock's volatility in relation to the overall market. Betting against beta (BAB) strategies have been performing incredibly well for investors, but economists have been unsure why. By drawing on more than 30 years of data, researcher Thorsten Lehnert has uncovered that flow-induced price noise has an important role to play.
MIT researchers developed a trajectory-planning system for autonomous vehicles that enables them to travel from a starting point to a target location safely, even when there are many different uncertainties in the environment, such as unknown variations in the shapes, sizes, and locations of obstacles.
Physicists have discovered that electrons in a crystal form counter-intuitive quantum links that are knotted. In explaining these phenomena, researchers turned to knot theory, a branch of mathematics that studies the complex world of knots and loops. This is the first time that knot theory has been used to understand materials called topological magnets, and the application of this theory promises to expand our knowledge of the quantum mechanics of materials.

A new study published in The Lancet estimates that RSV-attributable acute lower respiratory infection was responsible for more than 100,000 deaths in children under five across the globe in 2019. The study is the first to examine RSV disease burden in narrow age brackets, reporting that there were over 45,000 deaths in infants under six months old in 2019, with one in five of the total global cases of RSV occurring in this age group.
