I hold a degree in Economics and have developed extensive expertise in the quantitative management of portfolio risk. Throughout my academic journey, I explored advanced models such as Markowitz optimization, Risk Parity, Value at Risk (VaR), and Expected Shortfall (ES), applying them to real-world portfolio construction. As a retail investor myself, I manage a diversified portfolio that includes both real estate and financial strategies. In this book, I share methodologies and techniques that I have personally tested in practice, directly applying them to portfolio management and investment strategies. My aim is to provide readers with practical, concrete tools to approach financial markets with greater awareness and responsibility. I present the main theories of risk management with clarity and precision, offering an updated and accessible framework for investors at different levels of experience. Beyond writing, I nurture a strong interest in behavioural finance and remain committed to staying constantly informed about innovations and developments in the financial sector.
