Quantitative Team Framework - The investment framework of Wanjia's quantitative team aims to build a scientific, systematic, and iterative quantitative investment system to pursue continuous and stable excess returns.

Path to Defeat the Partial - Stock Fund Index: Dual - Enhanced Active Quantitative Strategy - Wanjia Quant uses a "dual - enhanced active quantitative strategy" to defeat the partial - stock fund index in the long term. First, it constructs an "excellent equity fund holding index" through quantitative algorithms, representing the overall stock - selection preference of excellent active equity funds in the market. Second, on the basis of this index, it further mines sources of excess returns by optimizing stock selection through multi - dimensional factor signals to obtain additional excess returns beyond the collective consensus of active funds [12]. 3.2.
