QuantumFira

Analyse a portfolio of stocks or ETFs from about two years of daily prices. QuantumFira builds a classical Markowitz maximum-Sharpe portfolio, fits it on the earlier part of the history and measures it on the later part, beside an equal-weight portfolio, so you see out-of-sample return, volatility, Sharpe ratio, drawdown and the most correlated pairs. For quantum portfolio optimisation, it writes the choice of assets as a QUBO, samples it with QAOA on the Amazon Braket SV1 quantum circuit simulator, weights the best valid selection classically and compares it with the classical portfolio on the same data, including how often QAOA sampled valid selections. Results are historical analysis for education and research, not financial advice.
