Market Efficiency: Myth or Reality? 🧠


Details
📢 Welcome to the Lux Finance/Investing Club’s upcoming meetup!
We’re excited to bring together finance enthusiasts, investors, and professionals from Luxembourg and beyond to tackle one of the most debated topics in all of finance: Are the markets truly efficient? Is trying to "beat the market" a fool's errand, or are there pockets of inefficiency that a smart investor can exploit? This event is for anyone who wants to understand the deep structure of how markets work.
🧭 Format of the Event
This is a casual, discussion-based gathering — no long presentations or slides. We'll sit around one or two tables, and your host Romain will kick things off with a 10-minute introduction to the Efficient Market Hypothesis before keeping the conversation flowing.
To help spark ideas, we recommend exploring the core concepts before the event. If you're new to the topic and don't know what market efficiency is, you can learn the basics in just 1 minute with this short video:

Don't worry, we'll still cover the fundamentals in the presentation at the start of the event! These ideas will simply help you form questions to bring to the table — feel free to come with your own experiences, doubts, and strong opinions!
We’ll also be releasing new short videos during the week. Follow on Instagram to not miss them!
👥 Who Can Join?
Everyone is welcome — whether you're:
- A firm believer in passive indexing.
- A curious skeptic who thinks there are edges to be found.
- A finance nerd who wants to debate the weak, semi-strong, and strong forms of efficiency.
- Or even a seasoned industry expert.
Feel free to bring a friend who might find this topic interesting – the more, the merrier!
Our goal is to create a friendly space where curiosity and experience meet — and where we all walk away smarter (or at least with a few good ideas and a drink in hand!).
