AI Score

AI Score is a stock rating system. Every company gets a single score from -100 to 100 that summarizes how attractive that business looks based on a large set of signals around value, quality, growth, financial strength, management, risk, and more.

The goal is simple: compress a complex investment picture into a single number you can use to quickly evaluate a company's potential reward and risk. Higher scores point to companies with stronger fundamentals and better outcomes. Lower scores point to weaker businesses, higher risk, overpriced valuations, or less attractive setups.

Our study on AI Score

Higher AI Scores correlates with better results

We grouped +10,000 stocks into score buckets and measured their performance over time in a roughly 50-year out-sample period. We used a 2-year holding period for each position, and the chart shows the avg. annual return and win ratio for each bucket.

The correlation is clear: Higher AI scores consistently line up with better results.

The AI score is designed to find companies with great fundamentals that are undervalued. However lower scores does not mean a company is necesarilly bad. A healthy company even at a reasonable price could get a low score if the margin of safety is not significant. In our study we found that even in the worst bucket between -100 and -90, 48% of the investments were still sold with a profit, and overall profitable buckets start appearing at an AI score of -60 to -50.

The available pool of high scoring companies to invest in also highly varies on market conditions, when the market is overvalued there will be fewer or sometimes no companies that receive a +90 AI score.

*Past performance does not guarantee future results. Historical studies are meant to show signal quality and correlation, not promise a specific return.

How it works

One score, built from a full company review

AI Score rolls a large amount of investment analysis into one number. Behind the score are more than 1,000 underlying signals and checks designed to capture the kinds of traits long-term investors care about most.

What a high score usually means

A high AI Score tends to show up in companies with better economics, healthier balance sheets, stronger profitability, better growth potential, more attractive valuations, and fewer red flags.

What a low score usually means

A low AI Score often points to weaker business quality, expensive pricing, deteriorating fundamentals, fragile finances, or a poor balance between upside and risk.

How to read it

Think of the score as a ranking, not a promise. Green, high positive scores suggest stronger candidates. Neutral scores suggest a mixed picture. Negative scores suggest the stock is less attractive and more likely to be filtered out.

How investors can use it

Use AI Score to screen for ideas, test your own portfolio, compare companies, validate your own research, build diversified baskets of high-ranking stocks, or add structure to a broader due diligence process.

Practical use

AI Score helps you spend time where it matters

Focus research on the companies most likely to deserve a deeper look.
Remove weak candidates faster instead of reading every stock from scratch.
Compare stocks on a common scale when building a watchlist or a portfolio.
Use it as a rating system alongside your own judgment, not as a substitute for judgment.

Unlike an actual performance record, backtested results do not represent actual trading and may not reflect the impact of brokerage commissions, slippage, or other fees. Because transactions may or may not have been executed, results may have under- or over-compensated for the impact, if any, of certain market factors, such as lack of market liquidity or level of participation.
