SS 3, LOS 7.a Question his, investment, successful, following, because

Benjiko

Which of the following most likely explains Tom Heggins’s behavior in investment decisions?
A) Tom uses anchoring to assess his skills.
B) Tom uses a top-down approach to assess his skills.
C) Tom uses the ceteris-paribus heuristic to assess his skills.
Your answer: A was incorrect. The correct answer was B) Tom uses a top-down approach to assess his skills.
Tom likely uses a top-down approach to assess his skills. Overconfident individuals will presume that because they are successful in one area of their life, they can be successful in other areas as well. (Study Session 3, LOS 7.a)
My question is how is being overconfident considered a “top-down” approach? My reasoning was that since he is overconfident he will “give disproportionate weight” to him being able to replicate his past success.
Can anyone argue for answer B? Thanks-
