Q72 Capital develops portfolio construction software for professional investors who want to understand how much a portfolio result depends on the method behind it. Instead of relying on a single optimization model, Q72 applies the same investment universe, constraints and risk profile across Q72 Confidence Alpha, Markowitz, Risk Parity and Black-Litterman. Each approach produces conservative, balanced and aggressive portfolios, which are then compared and tested out of sample against historical market data. This gives investment teams a clearer view of which results are genuinely robust and which are mainly driven by the chosen methodology. Quantum computing is used selectively within Q72 Confidence Alpha when it improves the result without increasing volatility. Q72 provides software and does not manage assets or offer investment advice.
