Question
Which of the following errors has Pedroia made in back testing his stock screen?
Answer Choices:
A. His results are subject to survivorship bias
B. His results are likely to suffer from multicollinearity
C. His results are likely to suffer from look ahead bias
Explanation
Pedroia should have assumed that he could purchase the stocks on the day the ratios
were published, not the year-end. As a result of this mistake, he is exposed to the
potential effects of look-ahead bias.
