The Price-to-Earnings (P/E) ratio measures how much investors are paying for each shilling of a company’s earnings. Formula: P/E = Share Price ÷ Earnings Per Share (EPS). For example, if a share trades at KSh 50 and earns KSh 5 per share, its P/E is 10×. This means investors are paying KSh 10 for every KSh 1 the company earns.
However, P/E should never be interpreted in isolation. A low P/E does not automatically mean a stock is cheap, while a high P/E does not automatically mean it is expensive.
P/E Ratio: An investor should consider:
– Historical P/E: How does the current valuation compare with the company’s normal valuation?
– Peer P/E: How is the company valued relative to similar businesses?
– Earnings growth: Are earnings growing fast enough to justify the multiple?
– Business quality: Are the earnings sustainable and supported by strong fundamentals?
– Future expectations: What earnings does the current share price appear to be pricing in?
The key investment question: Instead of asking: “Is the P/E low?” Ask: “What am I paying for, and are the company’s earnings capable of justifying that price?” A useful way to think about P/E is: Price → Earnings → Growth → Quality → Valuation
P/E therefore provides a starting point for valuation analysis, not a standalone buy or sell decision.
