Answer: The quadratic programming technique takes into account additional risk parameters compared to other major portfolio construction techniques but also requires more inputs, which leads to more noise.
A is correct. Quadratic programming requires many more inputs than other portfolio construction techniques because it entails estimating not only alpha but also volatilities and pair-wise correlations between all assets in a portfolio as well as transaction costs. Quadratic programming is a powerful process but given the large number of inputs and the less than perfect nature of most data, it introduces the potential for noise and poor calibration.

In the realm of financial risk management, firms employ various portfolio construction techniques to align with their risk control goals. Which of the following options precisely explains a portfolio construction technique and details its strategy for mitigating risk in accordance with the firm's predefined risk management objectives?
A
The quadratic programming technique takes into account additional risk parameters compared to other major portfolio construction techniques but also requires more inputs, which leads to more noise.
B
The screening technique ranks stocks by risk-adjusted alpha but it does not apply any additional risk control measures such as weighting the selected stocks by their relative capitalization.
C
The stratification technique splits the list of stocks into categories and maintains risk control by overweighting the categories with lower risks and underweighting the categories with higher risks.
D
The linear programming technique focuses on the pair-wise correlations of stocks rather than characterizing each stock along multiple dimensions of risk such as size industry, volatility, or beta.
