PROBLEMS<br />

Sample answers to<br />

problems marked with<br />

an asterisk appear in<br />

Appendix 4.<br />

(Problems 9.1 to 9.6 are all basic-level problems.)<br />

9.1* ‘The shares of XYZ plc are underpriced at the moment.’<br />

How logical is this statement about some shares quoted on the LSE?<br />

9.2* ‘Capital market efficiency in the semi-strong form implies that all investors have all of<br />

the knowledge that is publicly available <strong>and</strong> which bears on the value of all securities<br />

traded in the market.’<br />

Comment on this statement.<br />

9.3* ‘In view of the fact that the market is efficient in the semi-strong form, there is no value<br />

to investors in businesses publishing financial reports, because the information contained<br />

in those reports is already impounded in share prices before that information is<br />

published.’<br />

Comment on this statement.<br />

9.4 ‘A graph of the daily price of a share looks similar to that which would be obtained by<br />

plotting a series of cumulative r<strong>and</strong>om numbers. This shows clearly that share prices<br />

move r<strong>and</strong>omly at the whim of investors, indicating that the market is not price efficient.’<br />

Comment on this statement.<br />

9.5 ‘A particular professionally managed UK equity investment fund produced better<br />

returns last year than any of its rivals. This means that it is likely to outperform its rivals<br />

again this year.’<br />

Comment on this statement.<br />

9.6 ‘An efficient capital market is one in which the market portfolio contains no systematic risk.’<br />

Is this statement correct? Explain.<br />
