	1.	The stock price will decrease as the retained earnings increase (dividends decrease).
	2.	The stock price will increase as the retained earnings increase (dividends decrease).
	3.	Firms should follow a high payout policy.
	4.	The stock price will either rise or fall by a change in dividend policy.
