英文摘要：
In this paper, we present a novel approach to the generation of virtual scenarios of multivariate financial data of arbitrary length and composition of assets. With this approach, decades of realistic time-synchronized data can be simulated for a large number of assets, producing diverse scenarios to test and improve quantitative investment strategies. Our approach is based on the analysis and synthesis of the time-dependent individual and joint characteristics of real financial time series, using stochastic sequences of market trends to draw multivariate returns from time-dependent probability functions preserving both distributional properties of asset returns and time-dependent correlation among time series. Moreover, new time-synchronized assets can be arbitrarily generated through a PCA-based procedure to obtain any number of assets in the final virtual scenario. For the validation of such simulated data, they are tested with an extensive set of measurements showing a significant degree of agreement with the reference performance of real financial series, better than that obtained with other classical and state-of-the-art approaches.

中文摘要：
在本文中，我们提出了一种新的方法来生成任意长度和资产组合的多元金融数据的虚拟场景。通过这种方法，可以为大量资产模拟数十年的实际时间同步数据，生成各种场景，以测试和改进量化投资策略。我们的方法基于对真实金融时间序列的时间相关个体和联合特征的分析和综合，使用市场趋势的随机序列从时间相关概率函数中提取多元收益，同时保留资产收益的分布特性和时间序列之间的时间相关。此外，可以通过基于PCA的过程任意生成新的时间同步资产，以获得最终虚拟场景中的任意数量的资产。为了验证此类模拟数据，使用一组广泛的测量数据对其进行测试，显示出与真实金融系列的参考绩效有很大程度的一致性，优于使用其他经典和最先进的方法获得的一致性。
