The Boom & Bust Signal is an indicator developed by Professor Nouriel Roubini and David Brown based on both fundamental and statistical analysis that has been applied to different asset classes to measure the possibility of a market correction.The Signal measures Risk Asymmetry, Risk/Reward. It is a Digital Signal (Buy/Sell), easy to read, that indicates when one asset class is Overbought (Red BOOM), and it is time to reduce the exposure to that asset class, or Oversold (Green BUST), and it is time to increase exposure to the same asset class.
