Evidence-Based Investing for Everyone.
Validation, not hope.
AI gives individual investors professional research tools and knowledge. What’s often missing is context and knowing the right questions.
Our free course, Evidence-Based Investing for Everyone, teaches you how to build rigorously tested strategies from the ground up inside QuantConnect (free account). No programming required.
Built for any investor who wants to use AI to develop systematic, evidence-based investment strategies.
Evidence-Based Investing for Everyone
A beginner’s course for systematic quantitative investing
Five chapters take you from the basics of return and risk, through backtesting and the major families of strategies, to the validation process that decides whether a strategy is real. The course ends where a strategy meets your own constraints and goes to paper trading — every concept explained before it is used.
Course Content
Chapter 16 unitsMeasuring Return and Risk
The two numbers behind every investment
This chapter introduces measures used to describe how an investment has performed — measures like return, risk, correlation and the Sharpe ratio. Each one is explained and then calculated on real market data and real strategies. This lays the foundation for the chapters that follow.

Chapter 24 unitsBacktesting Strategies
Test your ideas before you trust them
A backtest applies a set of trading rules to historical data and reports what the result would have been. In this chapter you run backtests in QuantConnect and work through the mechanics that shape the result, such as order types, the bid-ask spread, dividends and trading costs. A backtest ends in a results page where each number answers a specific question, and the chapter works through what those questions are.

Chapter 36 unitsThe Universe of Strategies
Every major family, on one map
Most published strategies belong to one of a small number of families. This chapter covers them one at a time — trend and momentum, mean reversion and value, quality and low volatility, carry and income, asset allocation, and market regimes — each illustrated with real examples. It also states which families the course does not cover, and the reason in each case.

Chapter 47 unitsStrategy Validation
The backtest is just the beginning
A backtest describes how a strategy performed over one historical period. Whether that performance reflects a real edge is a separate question, and this chapter is about answering it: thirteen tests arranged in four ordered levels. Each level is demonstrated on real strategies, and the chapter ends with you running the full examination on a strategy of your own.

The QSL Strategy Validation Process — Thirteen questions to ask before you trust a backtest
Level 1: Validity — Three tests: is this result measurable at all?
Level 2: Edge — Three tests: is there a real edge here?
Level 3: Quality — Four tests: how good is the edge, and is it the strategy’s own?
Level 4: Overfitting — Three tests: did we find an edge, or invent one?
The Research Process — Your own strategy, from first idea to final verdict
Chapter 54 unitsFrom Validation to Paper Trading
What it takes to actually run one
A strategy that has passed validation still has to fit the person running it — their capital, time, risk tolerance and other constraints. The units here cover those constraints, how to combine strategies into an ensemble, what to monitor once one is running on paper, and how to set stopping conditions in advance. The course ends at paper trading; running a strategy with real money is treated as what comes after it.

Built by former institutional equity derivatives professionals.
QS Lab was built by former institutional equity derivatives professionals who spent over 40 years at JPMorgan, Lehman Brothers, Nomura, Morgan Stanley and other major financial institutions, advising institutional clients, investment funds and family offices on risk management.
Marcus and Martin met at JPMorgan in 1999, working together in the Equity Derivatives division. Within their first year they executed one of the largest equity derivatives transactions in Europe that year. Many more followed.
Marcus Di PrimaManaging Director
JPMorgan Chase, Lehman Brothers, Mediobanca, Commerz Financial Products & Zurich Insurance Group. 20+ years in institutional equity derivatives with a passion for flying, sailing, skydiving, kitesurfing, landscapes and trading.
Martin BertschManaging Director
Nomura, Lehman Brothers, JPMorgan Chase, Morgan Stanley. 20+ years of experience in equity and fixed income derivatives, with a passion for travelling, hiking, and photography.
What they discovered early: complementary skills and a shared focus produce better results than either person working alone. That principle has shaped everything they have built since.
Both retired from institutional finance at an early age. For most of their careers, working inside investment banking meant being restricted from making investment decisions in their own accounts — a standard condition for anyone operating close to material non-public information. When they left, that constraint lifted. They began building their own quantitative investment infrastructure from scratch.
QS Lab grew from that experience. The tools, frameworks, and validation processes that institutional investors use to evaluate strategies are not complicated — but they have always been inaccessible. Recent advances in technology and AI have changed that. Every serious investor can now work with the same rigour that professionals apply, with the right guidance.
This is our passion — and we want to share it with you.

With the right tools and guidance, you can go further than you’d expect.
