QUESTION 1
Continuous changing of the economic, technological and political
conditions caused the Human Resource Managers of the future facing
more problems in the management of labor. The Human Resource
Managers of today may find themselves outdated in the future due to
changes in the environment if they do not update themselves some of
the important challenges. If you are the Human Resource Manager,
detail out the threats or challenges that would arise and suggest
strategies to overcome those challenges.

The manager of an event-driven hedge fund becomes aware of some empirical evidence suggesting that companies having a very high value of PFCF (the ratio of stock price to free cash flow per share) relative to their industry average are likely to become targets for acquisition by other firms. The manager gathers the following data about companies of interest: • The probability that a company becomes an acquisition target during the course of a year is 0.45. • 73% of the companies that became acquisition targets had values of PFCF more than three times the industry average. • Only 25% of the companies that were not targeted for acquisition had values of PFCF more than three times the industry average. What should the hedge-fund manager conclude is the probability that a given company with a PFCF more than th

Work in empirical asset pricing has studied portfolios where stocks are grouped together on the basis of a ‘value’ measure (e.g. book-to- market value or earnings per share divided by price per share). What is the evidence on how mean returns vary across such portfolios and why does this provide a challenge to the Capital Asset Pricing model? How would you interpret the existence of differences in mean returns across value portfolios? [Write no more than 15 sentences in your answer.]
