One of the central tenets of classical test theory is that scales should have a high degree of internal consistency, as evidenced by Cronbach's α, the mean interitem correlation, and a strong first component. However, there are many instances in which this rule does not apply. Following Bol...

the S&P 500 or Nasdaq indexes. Then, isolate those stocks that are relatively weak or strong compared with the index. This creates an opportunity for the day trader, because a strong stock may move up 2% when the index moves up 1%. There is more opportunity in the stock that moves more...
