Factor Scores range from 0 to 100, with 100 being most desirable. Larger circles are better. In situations where we have no data (e.g. no insider trades), we plot the score at 50 to avoid penalizing companies. However, a company that does not pay dividends will get a Dividend Score of Zero. Additionally, we inverted volatility to create a "stability" metric which is better when higher.
