What the score is made of

Each factor is half a curve over reported figures and half a rank among the other Financials companies (momentum is judged against fixed thresholds only), and the five are blended by weight. The score is where that blend places it in the S&P 500. It describes the last filing and the current price. It is not a forecast.
