摘要:

到目前为止,在线投资组合选择研究主要集中在最大限度地减少财富增长方面的遗憾。然而,实际的财务决策与财富和风险密切相关。我们考虑在线学习的股票投资组合的价格是由任意(未知)平稳和遍历过程,其目标是最大化财富,同时保持条件风险价值(CVaR)低于所需的阈值。我们描述了渐近最优的风险调整后的性能,并提出了一种投资策略,其投资组合是保证达到渐近最优解,同时满足所需的风险约束。我们还数值证明和验证我们的方法在标准数据集上的可行性。

英文摘要:

Online portfolio selection research has so far focused mainly on minimizing regret defined in terms of wealth growth. Practical financial decision making, however, is deeply concerned with both wealth and risk. We consider online learning of portfolios of stocks whose prices are governed by arbitrary (unknown) stationary and ergodic processes, where the goal is to maximize wealth while keeping the conditional value at risk (CVaR) below a desired threshold. We characterize the asymptomatically optimal risk-adjusted performance and present an investment strategy whose portfolios are guaranteed to achieve the asymptotic optimal solution while fulfilling the desired risk constraint. We also numerically demonstrate and validate the viability of our method on standard datasets.
