7. Which of Silveira’s statements concerning momentum indicators is correct?
选项: A.
B.
C.
解释:
A is correct. Relative-strength indicators compare an equity’s performance with the performance of a group of equities or with its own past performance. SUE is unexpected earnings scaled by the standard deviation in past unexpected earnings (not the standard deviation of analysts’ earnings forecasts, which is used in the calculation of the scaled earnings surprise)
