Relative valuation assesses whether a security appears expensive or inexpensive by comparing its valuation multiples with those of comparable companies, an industry group or an appropriate historical range. The price-to-earnings ratio measures the market price assigned to each unit of company earnings. When companies have sufficiently comparable business models, growth prospects, risk characteristics and accounting policies, differences in their P/E ratios can help identify potential overvaluation or undervaluation.
A high P/E relative to suitable peers may indicate that the market expects superior growth, but it may also suggest that the shares are overvalued. A low relative P/E may indicate undervaluation, although it can also reflect weaker prospects or higher risk. The comparison therefore requires analysis rather than a mechanical conclusion.
Moving averages and momentum indicators evaluate price behaviour and trends; they do not directly compare market price with earnings or underlying value. Social-media sentiment measures investor attitudes, which may influence short-term price movements but does not provide a reliable fundamental valuation by itself.
The Retail Securities syllabus requires candidates to analyze value ratios, including earnings per share and price-to-earnings ratios, and to use external comparisons. It separately distinguishes fundamental valuation from technical, quantitative and behavioural approaches to assessing market activity.
