Decades of research in portfolio management   Quantitative Management (QM) is a technique founded on over 30 years of portfolio management research. The many theories involved in portfolio management, of which Capital Asset Pricing Model (CAPM) is the most widely-known, have led to a wide range of investor behaviour models. Each model aims to predict future market movements and measure the risks associated with them. These risks can be analysed according to potential returns, thus providing a risk management tool.   Although the development of computer systems and software has allowed the widespread application of these techniques, the reliability of the results they produce depends upon the quality of the forecasts they use, especially those relating to returns on financial assets.   Considering this, investment and risk management techniques take on considerable importance, and those applied by Bearbull meet the highest possible performance specifications.
