FINS5510 Chap.9 Share Returns and Portfolio Risk
Share Returns and Portfolio Risk
An ordinary share represents residual ownership in a company. Dividend yield divides annual dividend income by the share price. Total return combines price change and income relative to the starting value. Diversification combines exposures whose outcomes are not identical. Systematic risk is market-wide risk that diversification cannot remove. Company-specific risk arises from circumstances particular to one business.
In share investing, the planning decision asks how ordinary share interacts with company-specific risk under the household constraint. Break shareholder return into dividend income and price movement before comparing it with an alternative. A strong result from one company does not show that the exposure was appropriately diversified or repeatable.
Describe which risks are company-specific and which remain market-wide, then connect the position size to the household goal and loss capacity. Rebalancing or review should follow a stated threshold rather than excitement about a recent winner.
