About Us
If we publish our decisions, we also keep their results.
AlpAI Lab is a research publication that shares AI-driven company analysis and tests of investment methods, using the management of our own company's funds as its subject. We show live trading, analysis and score observations, simulated (paper) trading, and backtests on historical data as distinct categories.
GRID Start, Ltd. (グリッドスタート株式会社) develops and operates the site. It also publishes the decisions made by "AlpAI," a system that uses AI to manage US stocks with the company's own funds, along with estimates of trading rules and the results of the account. The person responsible for operations is Hideo Takahashi, President and Representative Director.
This page explains who runs AlpAI Lab, how its articles are made, and how conflicts of interest and corrections are handled, so you can judge how far to rely on what you read.
Why we publish decisions and results
An AI explanation that sounds plausible is not the same as one that is useful in actual investing. You need to look separately at the information available when a decision was made, the results that followed, and the conditions used for comparison.
AlpAI Lab covers not only the periods when performance was good, but also interim drawdowns and estimates in which the expected effect could not be confirmed. Our aim is to leave behind material that lets readers evaluate AI analysis and trading results with their conditions and limitations in mind.
Managing the company's own funds is a separate record from estimates based on historical data. A good account result alone is not treated as proof that a particular rule, or the AI, is effective.

How articles are made
Daily articles (decision records) and weekly articles (weekly reviews) are created and published by software. Checks are run before publication, but a person does not read each article before it is published.
AI is also used to write research articles, and we review the findings alongside the supporting sources.
Even though AI and programs are used, it is the operating company that checks and corrects the published content. We keep the decision made at the time separate from materials confirmed afterward, and we do not fill in reasons that are absent from the records with plausible-sounding text.
Conflicts of interest and corrections
Because the company trades US stocks with its own funds, it may hold or trade the stocks discussed in articles. The company's interests and readers' interests do not necessarily align. Each article describes decisions as of the date it covers. Conflicts of interest that we confirm will be disclosed in the article or on a related page.
If we find an error, we correct it. Later results do not change the record of what we decided at the time.
