What is the Health Score and how to interpret it?
When analyzing a stock, you face dozens of metrics: ROE, P/E, debt/equity, margins, growth... StocksAnalyzer's Health Score synthesizes all of that into a number from 0 to 100 so you can get a first impression of the company in seconds.
Think of it as a company's blood test: a single number that tells you whether the patient is healthy, has some out-of-range indicators, or needs urgent attention. It doesn't replace the doctor, but it's the essential first step.
How is the Health Score calculated?
The Health Score weighs five fundamental dimensions, each with a different weight in the final calculation:
| Dimension | Key metrics | What it evaluates |
|---|---|---|
| Profitability (25%) | ROE, net margin | Does the company earn more than it spends? |
| Valuation (20%) | P/E ratio vs. sector | Is it cheap or expensive relative to the market? |
| Debt (25%) | Debt/equity, interest coverage | Can it meet its financial obligations? |
| Growth (15%) | Revenue and earnings variation | Is it growing or stagnating? |
| Efficiency (15%) | ROA, asset turnover | Does it make good use of its resources? |
Each dimension receives a partial score and the final Health Score is the weighted sum. A company can have excellent profitability but heavy debt, which will drag its total score down.
How to interpret the result?
| Score | Status | What it means | Recommended action |
|---|---|---|---|
| 80 – 100 | Excellent | Solid company across all metrics. Low financial risk. | Analyze in depth as a buy candidate |
| 60 – 79 | Good | Healthy fundamentals with some minor weak points. | Review which dimension is dragging the score |
| 40 – 59 | Acceptable | Mediocre company or in a difficult sector. | Requires deeper analysis before investing |
| 0 – 39 | Weak | Important warning signs. High financial risk. | Avoid unless you have a very clear investment thesis |
Real examples: Apple, NVIDIA and Tesla
To understand the Health Score in context, let's look at three well-known companies with very different profiles:
- •Apple (AAPL) — Health Score ~75/100: Exceptional ROE (>150%), 25% net margins, manageable debt given its enormous cash flow. The only drag is a high P/E (~28x) reflecting market expectations.
- •NVIDIA (NVDA) — Health Score ~82/100: ROE above 100%, 55% margins driven by AI demand, explosive revenue growth. Very high P/E (>30x) due to future expectations.
- •Tesla (TSLA) — Health Score ~52/100: Margins under pressure from the price war, moderate debt, volatile ROE. Strong growth but very demanding valuation.
The contrast is clear: NVIDIA has exceptional fundamentals even though it trades at a premium. Tesla has weaker metrics but a different growth profile. Apple sits at a solid middle ground.
Is the Health Score enough?
No. The Health Score is a starting point, not a final verdict. A company can have a low Health Score because it is in aggressive growth mode (like Amazon in its early years, with negative ROE and heavy debt to finance its expansion) and still be a great investment.
It also does not account for qualitative factors like management quality, competitive advantages (moat), the macroeconomic context or regulatory risks. Numbers are the starting point, not the destination.
How to combine the Health Score with other indicators
The most complete analysis combines the Health Score with:
- •RSI: If the Health Score is high (solid company) and the RSI is in oversold territory (<30), it may be an opportunity to enter at a good price.
- •Monte Carlo projections: A company with a Health Score of 70+ and a favorable Monte Carlo scenario has an attractive risk/reward profile.
- •Analyst consensus: If the Health Score is high and analysts have a price target above the current price, the convergence of signals reinforces the thesis.
- •Price trend: A high Health Score in a company whose price has been falling for 6 months may signal a value opportunity.
Common mistakes when using the Health Score
- •Comparing companies from different sectors: A utility with a Health Score of 65 may be a better investment than a tech company with 70, because utilities naturally carry more debt.
- •Ignoring the time context: A Health Score that has fallen from 80 to 55 in two quarters is more worrying than one that has been stable at 55 for years.
- •Making decisions based solely on the number: It is a filtering tool, not an automatic investment algorithm.
Frequently asked questions
Is a Health Score of 50 bad?
It depends on the sector and context. In sectors with structurally low margins (retail, utilities) a score of 50 can be normal. In technology, where margins tend to be high, a 50 does indicate relative weakness.
How often is the Health Score updated?
The Health Score is recalculated with each analysis, using the latest available financial data for the company (most recent quarterly or annual reports).
Can a company with a low Health Score still go up in price?
Absolutely. The market prices in future expectations, not just the current state. A company with weak fundamentals but undergoing restructuring can rise significantly if the market anticipates improvement. The Health Score measures where it is today, not where it is going.
What Health Score do the best companies in the world have?
Companies with consistently high Health Scores (>80) tend to be those with a defensive moat: Microsoft, Apple, NVIDIA, Johnson & Johnson, Visa. Aggressive growth companies like Amazon or Tesla may have lower scores due to their financial structure.
