Question:

Your investment advisor called to suggest buying ABC Company and noted that its P-E was only 20 and the rest of the companies in its industry had P-Es of around 28. You looked in the Wall Street Journal and found it reported a P-E of 32 for ABC Company and an average P-E of around 30. How can you make sense of this?
