This visualization maps major US stocks as satellites orbiting the market. Distance from the center captures each stock’s market sensitivity: inner positions correspond to low beta and stable price dynamics, while outer orbits reflect higher beta and greater volatility. Circle size reflects market capitalization, scaled so that the central circle represents the total US equity market (approximately USD 60 trillion), while each other circle represents the relative size of an individual stock. The Healthcare sector cluster near the center (blue) has the lowest average beta, while Technology stocks (red) exhibit the highest average beta. 

Data: Stock betas and market capitalizations for the 50 largest US companies. Beta estimates are based on weekly returns over the past 250 weeks.
