100: The best of its peers
About 4× as likely as the average stock to become a ten-bagger, and about half as likely to be wiped out.*
90: Beats 9 in 10 peers
About 1.6× as likely as the average stock to become a ten-bagger, and about half as likely to be wiped out.*
50: Middle of the pack
Half its peers score higher, half lower. For every stock here that became a ten-bagger, about 4 were wiped out.*
10: 90% of its peers score higher
About 1.7× as likely as the average stock to be wiped out.*
* Compared with all stocks, of which 1.7% became ten-baggers and 9.5% were wiped out. 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; a wipe-out is one that lost 90% or more. Hypothetical results; past performance does not guarantee future results.
Most tools ask you to believe their track record. We don’t.
Every quarter we choose every US stock scoring 90 or higher and lock that choice in public before the quarter begins. We cannot change it. When the quarter ends we show what those stocks actually returned, good or bad. Want to see how we do this 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. MonkStreet is built so you don’t need those alerts. One score tells you whether a company still deserves to be owned for years.
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.
Bought at 90 or more. Kept 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 ~$91,000, and the S&P 500 into ~$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-listed 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.

Yearly return by score group, 1999 to 2026
Each solid bar is one score group. Every quarter, we sorted US-listed companies above a minimum size by score and bought equal amounts of each, even those that later failed. The striped bar, “No score”, is the 19% of companies we refuse to score because their records are too short or incomplete. They did worst of all, below even the lowest scores. Hypothetical results, before costs.

If it fits, try it free for 14 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.

Frequently Asked Questions
MonkStreet is a research platform. It gives more than 7,000 stocks a MonkScore from 0 to 100, based on the numbers behind each business. Most tools only help you buy. MonkStreet also tells you when a stock no longer deserves a place in your portfolio.
The Investor plan costs $399 a year. Pay for two years and you save $120. If you manage money for clients, you need the Advisor plan: $2,400 a year for your firm, with 3 users. Both include every score and its history, the screener and a weekly email about the stocks you own. Try it free for 14 days first.
Very likely, if it is listed in the US, Canada, Europe, Japan, Australia, Hong Kong, Israel, Singapore, Taiwan or South Korea and is worth more than $300 million. We score more than 7,000 companies. We do not yet cover mainland China, India, Brazil, Mexico, Saudi Arabia, Turkey, Indonesia or Thailand, so search any ticker to check a stock you own. Each company also needs enough data and history to score fairly. If we cannot score a company well, we show no score.
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, you need the Advisor plan, and 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 measures, 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.
Anytime, in one click in Settings → Billing. You do not need to email support or call anyone. We hate those traps too. We email you before the trial ends, and if you cancel during the trial, you pay nothing.
