Question

Active trading in markets and competition among securities analysts helps ensure that: I. Security prices approach informational efficiency. II. Riskier securities are priced to offer higher potential returns. III. Investors are unlikely to be able to consistently find under- or overvalued securities.

Answer 1

Answer:

The answer is: All the options are correct (I, II and III)

Explanation:

The larger the number of individuals (e.g. securities analysts, investors) who are informed about the price system of securities, the prices of securities will approach informational efficiency.

When the system approaches informational efficiency, you can determine which securities are riskier than others. Therefore you can price riskier securities so that they offer higher expected returns.

The other positive effect of informational efficacy is that investors can determine which securities are undervalued or overvalued.
