Before we start, you'll need to understand a few key terms and concepts, namely alpha, beta, systematic risk and idiosyncratic risk. Beta - The return generated from a portfolio that can be attributed to overall market returns. Exposure to beta is equivalent to exposure to systematic risk. The alpha is the portion of a portfolio's return that cannot be attributed to market returns, and is thus independent from market returns.
Barchart.com takes this Alpha (measure of how much a stock has changed in the one-year period) and weights this, assigning more weight to recent activity, and less (0.5 factor) to activity at the beginning of the period. Thus the Weighted Alpha is a measure of one year growth with an emphasis on the most recent price activity.
