Quantitative Investment, built on the solid foundation of robust financial theories, is at the center stage in investment industry today. The essence of quantitative investment is the multi-factor model, which explains the relationship between the risk and return of equities. However, the multi-factor model generates enormous quantities of factor data, through which even experienced portfolio managers find it difficult to navigate. This has led to portfolio analysis and factor research being limited by a lack of intuitive visual analytics tools. Previous portfolio visualization systems have mainly focused on the relationship between the portfolio return and stock holdings, which is insufficient for making actionable insights or understanding market trends. In this paper, we present s Portfolio, which, to the best of our knowledge, is the first visualization that attempts to explore the factor investment area. In particular, sPortfolio provides a holistic overview of the factor data and aims to facilitate the analysis at three different levels: a Risk-Factor level, for a general market situation analysis; a Multiple-Portfolio level, for understanding the portfolio strategies; and a Single-Portfolio level, for investigating detailed operations. The system's effectiveness and usability are demonstrated through three case studies. The system has passed its pilot study and is soon to be deployed in industry.

sPortfolio：股票投资组合的分层可视化分析。

定量投资基于稳健的金融理论的坚实基础，是当今投资行业的中心阶段。量化投资的本质是多因素模型，它解释了股票风险与收益之间的关系。但是，多因素模型会生成大量的因素数据，即使是经验丰富的投资组合经理也无法通过这些数据进行导航。由于缺乏直观的视觉分析工具，导致投资组合分析和因素研究受到限制。先前的投资组合可视化系统主要关注投资组合收益与股票持有量之间的关系，不足以做出可行的见解或了解市场趋势。在本文中，我们介绍了投资组合，据我们所知，是第一个尝试探索要素投资领域的可视化。sPortfolio特别提供了因素数据的整体概览，旨在促进三个不同级别的分析：风险因素级别，用于一般市场情况分析；多重投资组合级别，用于了解投资组合策略；和单一组合级别，用于调查详细操作。通过三个案例研究证明了该系统的有效性和可用性。该系统已经通过了试点研究，即将在工业中部署。多重投资组合级别，用于了解投资组合策略；和单一组合级别，用于调查详细操作。通过三个案例研究证明了该系统的有效性和可用性。该系统已经通过了初步研究，即将在工业中部署。多重投资组合级别，用于了解投资组合策略；和单一组合级别，用于调查详细操作。通过三个案例研究证明了该系统的有效性和可用性。该系统已经通过了初步研究，即将在工业中部署。
