Answer:
A) have zero alphas
Explanation:
Stock's alpha show show much they have over or under performed in relation to similar peer stocks. But if the stocks were correctly priced, then alpha should be 0 since no variation, either positive or negative should occur. Alpha basically measures the error in the stock's valuation. It is always better to have positive alphas because if you make a mistake then hopefully is in your favor, but alphas can also be negative and that equals unexpected losses.
This is why the CAPM model only considers beta in its calculation.
