What Is a Stock Rating?
On this page
A stock rating condenses a company's fundamentals and its stock's behavior into a single score, so you can compare many companies at a glance.
Ratings come in two kinds: analyst ratings written by people, and quantitative ratings built by a model. MoatMint's is the second kind. It scores thousands of companies from 0 to 10, updated each day after the market closes.
What is a stock rating?
A stock rating turns a lot of analysis into one quick score you can compare.
Analyst ratings come from people. A research analyst studies a company and gives an opinion in words: buy, hold or sell. You will also see overweight (hold more of the stock than the market does), underweight (hold less) and labels like outperform or neutral. Each one is a single expert's opinion, and it usually comes with a price target.
Quantitative ratings, or quant ratings, come from a model. The same rules run over every company's numbers, so the score is consistent. No single analyst's mood or opinion changes it. The limit is that a model only sees what it is built to measure. MoatMint, Morningstar, New Constructs and Seeking Alpha's Quant ratings all work this way, turning raw financial data into one comparable grade.
Neither kind should be confused with a credit rating. Agencies like Moody's and S&P grade a company's debt and its odds of default, not whether its stock is worth owning - a different question with a different scale.
MoatMint is one of these models. It builds each rating from a company's financial results and price history, then refreshes it after every market close. Every company is scored on the same 0 to 10 scale, so any two can be compared side by side. Many of the inputs, like return on invested capital (ROIC), are standard measures investors already know.
What does the MoatMint rating measure?
MoatMint shows five factors, each scored from 0 to 10, then blends them into one overall MoatMint rating, also 0 to 10. Each factor builds on a familiar idea from fundamental analysis.
- Quality asks how good and how lasting the business is. It checks how efficiently the company turns its assets into profit, how much of that profit becomes real cash, and whether the business can grow without relying on debt or diluting shareholders. Durable, high returns on capital are the fingerprint of an economic moat - an edge that lets a company keep its profits instead of losing them to rivals.
- Momentum measures price momentum, or relative strength: how the stock has performed against the wider market over roughly the past year, setting aside the most recent few weeks, and confirmed by trading volume. Reading price momentum this way follows factor-investing research linked to firms like AQR. It is shown as data about how the stock has traded, never as a signal to act now.
- Growth looks at whether the business itself is speeding up: sales and earnings that are accelerating, and returns on capital improving. Think of it as the business-side counterpart to a rising share price.
- Value asks what you pay for those profits. It weighs the price against the company's operating earnings and free cash flow, using enterprise-value yields rather than the share price alone. A great business can still be a poor buy if the price already assumes everything goes right.
- Financial health checks whether the company can survive hard times. It reads the balance sheet: how much debt the company carries, how much cash it holds and how close the business sits to financial distress over the coming year. A fast-growing, cheap-looking stock is far riskier when the balance sheet is fragile.
You can read each factor on its own, or look at the combined rating for one quick answer, laid out in our guide to how the MoatMint rating works. The exact way MoatMint weights and blends the factors is proprietary. The ideas behind them come from standard finance.
How a stock rating handles conflicting signals
This is what a single number is really for. Real businesses rarely score well on everything: a great company can have a quiet stock, and a soaring stock can hide a weak business. The rating has to settle those conflicts. The two examples below are simplified, with the scores rounded on purpose.
Example A: high quality, weak momentum
| Factor | Score (0-10) |
|---|---|
| Quality | 9 |
| Momentum | 3 |
| Growth | 5 |
| Value | 6 |
| Financial health | 8 |
This is a strong, cash-rich business with a solid balance sheet whose stock has gone nowhere lately. Quality is excellent, financial health is sound, growth is steady and the price is fair, but the market has been ignoring it. With four of the five factors in good shape, the overall score is still upper-middle. This looks like a good business in a slow stretch, not a broken one. It does not reach the very top, though, because the weak stock pulls momentum down.
Example B: hot momentum, thin quality
| Factor | Score (0-10) |
|---|---|
| Quality | 3 |
| Momentum | 9 |
| Growth | 8 |
| Value | 2 |
| Financial health | 4 |
This is the crowd favorite: a fast-moving, fast-growing stock everyone is talking about, but with weak quality and a rich price. Look at momentum alone and the stock seems like a top pick. The combined rating comes out well below that, around the middle of the scale, because weak quality, a shaky balance sheet and a high price pull it down. That gap is the rating doing its job: a rising price alone cannot carry a weak business to a top score. For a quality-focused investor, that one number is a cue to look closer before you get caught up in the hype.
Both examples show the same thing: the overall rating is not a plain average. A great business with a quiet stock is not overlooked, and a weak business with a popular stock is not overrated. The result is one clear score for the whole business.
A stock rating is not a price target
People mix these two up all the time, partly because analyst ratings so often come with a price target. A price target guesses where a stock might trade later on. A rating describes the business and its stock as they are today, in a consistent way. They answer different questions, and one cannot stand in for the other.
MoatMint publishes ratings on purpose - not price targets, and no buy or sell recommendations. A price target asks you to act on a forecast. A rating asks you to compare, then research. That fits how patient long-term investors work: weigh the business first, then wait for a price that makes sense.
How long-term investors use a stock rating
A rating works best as a filter, not a verdict. It points you toward businesses worth your time and away from the rest, so you spend your research hours where the evidence is strongest. From there the real work begins: read the financials, understand the moat and decide whether the price leaves room for error.
That is how a stock rating fits a patient, quality-first approach: keep finding genuinely good businesses, and keep adding to the ones you already understand. You can screen high-quality companies by their Quality rating, then research the names that stand out. You can also learn what gives a business a lasting edge in our guide to wide-moat companies.
