• JUMP (DIFFUSION PROCESS)
  
  Is the phenomenon by which a market experiences a significant departure from a price level. This departure can be either higher or lower. It is thought that these occurrences support "fat tails" assumptions and methodologies. These fat tails alter the statistical expectations of normal curve procedures. The graphical appearance of this occurrence looks as a gap in the data or it chart.
