the meaning and importance of return to investors

10.2 Analysis of Published Accounts – Investment Ratios

What are Investment Ratios?

Investment ratios help investors understand how well a company uses its resources to generate profit and rewards. Think of them as the “health check” for a company’s financial performance.

Why Do Investors Care?

💰 Return to investors is the main goal: the more profit a company makes and the more efficiently it uses its assets, the higher the potential return for shareholders.

📈 Investors use these ratios to compare companies, assess growth potential, and decide whether to buy, hold, or sell shares.

Key Investment Ratios

RatioWhat It MeasuresFormula (LaTeX)
Return on Equity (ROE)Profit generated per pound of shareholders’ equity.\$\\displaystyle \\text{ROE} = \\frac{\\text{Net Income}}{\\text{Shareholders' Equity}}\$
Return on Assets (ROA)Profit generated per pound of total assets.\$\\displaystyle \\text{ROA} = \\frac{\\text{Net Income}}{\\text{Total Assets}}\$
Return on Investment (ROI)Profit relative to the amount invested.\$\\displaystyle \\text{ROI} = \\frac{\\text{Net Profit}}{\\text{Investment Cost}}\$
Dividend YieldCash returned to shareholders as a percentage of share price.\$\\displaystyle \\text{Dividend Yield} = \\frac{\\text{Annual Dividends per Share}}{\\text{Share Price}}\$

Analogy: Investment Ratios as a Car Dashboard

Imagine a car’s dashboard: the speedometer tells you how fast you’re going, the fuel gauge shows how much fuel you have left, and the engine temperature gauge warns you of overheating. Similarly:

  • ROE = “Speed” – how quickly the company turns equity into profit.

  • ROA = “Fuel Efficiency” – how well the company uses all its assets.

  • ROI = “Trip Cost” – how much profit you get for the money you invested.

  • Dividend Yield = “Fuel Price” – the return you get for each share you own.

Example Calculation

Suppose Company X has the following figures (in £000):

ItemAmount (£000)
Net Income120
Shareholders’ Equity400
Total Assets800
Investment Cost500
Annual Dividends per Share0.50
Share Price10

Now calculate:

  1. ROE: \$\\displaystyle \\frac{120}{400} = 0.30\$ or 30%

  2. ROA: \$\\displaystyle \\frac{120}{800} = 0.15\$ or 15%

  3. ROI: \$\\displaystyle \\frac{120}{500} = 0.24\$ or 24%

  4. Dividend Yield: \$\\displaystyle \\frac{0.50}{10} = 0.05\$ or 5%

Interpretation: Company X turns equity into profit at a 30% rate – quite high! It also uses assets efficiently (15% ROA) and offers a decent dividend yield.

Exam Tips

  • Always show the formula in LaTeX when writing your answer.

  • Explain what each ratio tells you about the company’s performance.

  • Use real numbers from the case study to calculate the ratios.

  • Compare the ratios to industry averages or the company’s past performance.

  • Remember: a higher ROE or ROA usually indicates better profitability, but check for sustainability.

Common Mistakes to Avoid

  • Using gross profit instead of net income for ROE/ROA.

  • Ignoring the time period – ratios should be calculated for the same year.

  • Failing to explain the significance of the ratio.

  • Assuming a high ratio is always good – check for one‑off events.

Quick Recap

Investment ratios help investors gauge how well a company uses its resources to generate profit and rewards. The main ones are:

  • ROE – profit per pound of equity.

  • ROA – profit per pound of assets.

  • ROI – profit relative to investment cost.

  • Dividend Yield – cash return per share.

Use them to compare companies, assess growth, and decide on investment actions.
