What makes us different
We take a stance
No "on one hand, on the other hand." Every signal, insight, and report delivers a clear opinion backed by data — bullish or bearish, with the reasoning shown.
Real money, real returns
Our model portfolio has been live and public since March 2021. Every entry, every exit, every equity curve. We run our own capital on the same strategies you see here.
No black boxes
Factor models, backtesting methodology, signal construction — all documented and explained. If you can't understand how a signal is built, you shouldn't trust it.
Who We Are

Independent. Systematic. Helsinki-based.

Antitrend Lab is built by a small team of quantitative investors and engineers in Helsinki, Finland. We started because the tools we wanted didn't exist — opinionated, fast, and honest about methodology.

Antitrend Lab combines human investment insight with AI-powered analysis. Our quantitative models are built and maintained by experienced investors. AI accelerates the research — it doesn't replace the judgment.
