Evidence of which behavioral bias is most likely to be found when analyzing the Lunnar C fund?选项：
A.Survivorship B.Look-ahead C.Confirmation解释：
SolutionC is correct. Confirmation bias, a cognitive error sometimes referred to as “stock love bias,” is the tendency of fundamental-based analysts and investors to look for information that confirms their existing beliefs about their favorite companies and to ignore or undervalue any information that contradicts their existing beliefs. Both look-ahead bias and survivorship bias are risks inherent in backtesting quantitative active strategies.
A is incorrect. Survivorship bias is a risk inherent in backtesting a quantitative active strategy. This approach creates a bias whereby only companies that have survived are tested and it is assumed that the strategy would never have invested in companies that have failed. Survivorship bias often leads to overly optimistic results and sometimes even causes investors to draw wrong conclusions.
B is incorrect. Look-ahead bias is a risk inherent in backtesting a quantitative active strategy. This bias results from using information that was unknown or unavailable at the time an investment decision was made. An example of this bias is the use of financial accounting data for a company at a point in time before the data were actually released by the company.
