what is the differnce between these two fields?

and what might be better to choose as a career?
im still young, not yet ready to make a choice yet, but i just want an idea on whats available


i have few questions. can someone give me some idea about this:

1. In view of the fact that the market is efficient in the semi strong form, there is no value to investors in companies publishing accounting reports, because the information is already impounded in share price before that information is published.

2. What are stock market anomalies? Why they are important in relation to stock market efficiency theory?

3. ‘The shares of ABC are under priced at the moment’. Comment on the validity of this statement.
