What the number means
Each company is ranked against its industry peers in its region when there are enough of them; otherwise against all companies in its region. Higher is better, like a credit score.
100: The best in its industry
The highest-rated company in its peer group. About 4× as likely to become a ten-bagger, and still less likely to lose 90% or more.*
90: Ahead of most peers
Ranked above 89% of its peers. US stocks at 90+ make our track record. Over ten years, 2.7% became ten-baggers and 4.4% lost 90% or more.
50: Middle of the pack
Half its peers score higher, half score lower. Over ten years, 1.6% became ten-baggers and 6.4% lost 90% or more.
10: Near the bottom
90% of its peers score higher. Over ten years, 16.0% lost 90% or more and 27% lost more than half.
* Compared with all stocks, of which 1.7% became ten-baggers and 9.5% lost 90% or more. Ten-year figures: what happened to each company over ten years, started every quarter from 1999 to 2016. A ten-bagger is a stock that rose tenfold. Hypothetical results; past performance does not guarantee future results.
We test the score in public.
On October 1, before the market opened, we sealed a list of every US stock scoring 90 or more. Its seal is public, so we cannot change the list in secret. On January 1, we open it and compare its return with the equal-weight S&P 500. One quarter proves little, so we repeat this every quarter.
Too much information can hurt your returns.
You do your research and make a plan. One morning, a news alert and your social feed give you an excuse to break it. You sell a stock you meant to hold, or you keep one you meant to sell.
Buying the story
The story sounds great, so you buy. A year later, it is still only a story.
Selling too early
You sell when the stock doubles. Then it keeps going up without you.
Holding too long
The stock keeps falling. You keep waiting for it to come back.
“Buy the stocks that score 90 or more. Keep them while they stay there.”
That simple strategy would have turned $10,000 into about $213,000 over 27 years, before costs. The average stock, held the same way, turned it into about $91,000, and the S&P 500 index into about $83,000.

Backtested hypothetical results, before costs. All figures include dividends. The test counts every delisted and bankrupt company at its final price. “Average stock” is every US company above our size floor, held in equal amounts. Past performance does not guarantee future results.
What the score measures.
Growth
Is the company growing faster than its peers, and can that growth last?
Profitability
Does the company earn more on its money than its peers?
Quality
Does the company turn its profits into cash and reinvest them wisely?
Market Conviction
Does the market value this company above its peers, or price it as if something is wrong?
Safety
Is the company free of the warning signs that often come before a big loss?
High scores led. Low scores lagged.
Next time a headline makes you want to sell, check the score first.
Yearly return by score group, 1999 to 2026
Every quarter, all scored companies above our size floor were sorted into ten groups by score and held in equal amounts until the next quarter. Failed companies count at their final price. Hypothetical results, before costs. The axis starts at 5%.

Check the fit before you sign up.
If it fits, try it free for 15 days. If it does not, save your money.
A good fit if:
You pick your own stocks.
You want new ideas, and a second opinion on your own.
You plan to hold for years.
Prices tend to follow great businesses. The score helps you find them early. You have to be patient.
Knowing when to sell feels even harder than buying.
You have sold a winner too early, or held a loser for too long. You want a clear rule for both.
Not a fit if:
You trade every week.
The score follows the business, and businesses change slowly. It will not tell you what moves next week.
You want someone to decide for you.
MonkStreet ranks stocks and shows you why. What you buy, and when, is up to you.
You expect every stock to win.
Some high-scored stocks still lose money. In the backtest, the score worked on average, across many stocks and many years.

Very likely, if it is a company worth more than $300 million. We score about 8,000 companies in the US, Canada, Europe, Japan and emerging markets. Each company also needs enough data and history to score fairly. If we cannot score a company well, we leave it out rather than guess.
We designed the MonkScore on 2015–2024 data. Its five pillars, its ratios and the way it combines them were set on those years, and they have not changed since. Later versions fixed bugs, cleaned data and made the rules consistent. None of them refitted the model to the past. We then ran the finished model on every year from 1999 to 2026, including the years before 2015 that played no part in its design. The final test is the future: every quarter since October 2026, we seal our list before the market opens and publish the result, good or bad. That is no guarantee, but you never have to take our word for it.
No. It shows you how every stock scores and why, so you choose with better information. The score does not know your goals, your portfolio or how much risk you can take, so the decision stays with you. If you use it for client work, your compliance team should review it.
Yes. Every score opens into its five pillars and shows where the company ranks against its peers, with 158 ratios, each ranked against the company's peers. Our methodology page explains how we built and tested the model. The exact recipe behind the MonkScore and its weights stay private. You can see enough to judge any score, but not enough to copy it.
