New Stockpointer Beta

The formula we used to calculate the beta (β) for companies has changed. The 5-year quarterly beta (20 observations) have been replaced by a weekly 2-year beta. (104 observations)

Changes were made for the following reasons:

  • 2-year beta is widely used across the industry.
  • 2-year beta includes more observations, therefore reducing estimation errors.
  • 2-year beta reflects fundamental changes of a company more accurately and relevant to today’s price.

This results in a small adjustment to the SP scores. (-/+ 1 or 2 points)

The previous definition of the “5Y beta on quarterly prices” will be replaced to reflect the new formula.
