About ACCE Investments

I built ACCE to answer one question for any stock: what is it actually worth? This is how it started, how it works, and what you can expect from me.

What ACCE Investments is

ACCE Investments is a stock research site. I run valuation models on more than 5,000 stocks, with up to six models per stock, and every stock page shows how each model reached its number. Each page also shows two separate figures:

From the models

Model fair value

The consensus of the valuation models. Fixed formulas applied to the company's own numbers, with no opinion added.

From me

ACCE price target

My own analyst-style target. It is dated, and built with the help of AI that reads far more filings, data and text than I could alone.

The site is available in English, French and Spanish. I also publish weekly picks with a public track record, including the ones that lost.

Who I am

Adrien Chantreuil
Founder

I’m Adrien Chantreuil, a sole trader based in Spain. I built this site and I write under my own name.

My background has nothing to do with finance. I come from aerospace engineering and air transport management. But numbers are just numbers, whatever field they come from, and that’s the beauty of it.

How ACCE came to be

  1. Investing at 24

    I started investing at 24. Like many people, I was drawn to value investing: buying good businesses for less than they are worth.

    The problem is that “what a business is worth” is very subjective. Two people can look at the same company and reach very different answers. My own biases crept into my estimates too.

  2. Taking my opinions out

    So over the years, I built valuation models to take my opinions out of the process and focus on the numbers themselves. That’s why each stock gets up to six models, and why the site shows how each one reached its number.

  3. A rough website and an Instagram account

    The models turned out to be quite good, so I decided to share them. It started small: a rough website and an Instagram account, nothing polished, just the numbers.

  4. AI changed what one person can do

    Then AI arrived, and it got more capable every year. It helped me build a far better website than the first one.

    It also changed the research itself. Reading the filings, reports and data behind a single company used to take me days. With AI I can analyse a much wider range of data and text, across thousands of companies, and keep it up to date.

  5. Everything in one place

    There was one more reason. To get all the information I wanted, I was paying for several subscriptions and still jumping between sites. ACCE is the tool I wanted for myself: valuations, data and reasoning, all in one place.

What you can count on

  • How I make money

    Most of my revenue comes from subscriptions.

    If you use the site for free, you may see links to brokers. These are affiliate links, and they are labelled as such.

  • How I use AI

    The valuation models are not AI. The model fair value comes from those models alone.

    AI helps me analyse far more data and text than I could by hand, and that work feeds the ACCE price target. It also writes short summaries of filings and earnings reports, which carry a “Written with AI” label, and it helps me turn my own notes into clear writing.

  • Corrections

    If you find a mistake, tell me through the contact page. I fix it and note the change.
