- The GAN_GRU factor is based on the GAN_GRU model, which utilizes a Generative Adversarial Network (GAN) for processing volume-price time series features and then uses a GRU model for time series feature encoding to derive the stock selection factor[4][13][14] - The GAN_GRU model includes two GRU layers (GRU(128, 128)) followed by an MLP (256, 64, 64), with the final output prediction return (pRet) used as the stock selection factor[22] - The GAN model consists of a generator and a discriminator. The generator aims to generate data that appears real, while the discriminator aims to distinguish between real and generated data. The generator's loss function is $L_{G} = -\mathbb{E}_{z\sim P_{z}(z)}[\log(D(G(z)))]$[23][24][25] - The discriminator's loss function is $L_{D} = -\mathbb{E}_{x\sim P_{data}(x)}[\log D(x)] - \mathbb{E}_{z\sim P_{z}(z)}[\log(1-D(G(z)))]$[27][28][29] - The GAN_GRU model's training process involves alternating training of the generator and discriminator until convergence[30] - The GAN_GRU factor's performance from January 2019 to September 2025 shows an IC mean of 0.1136, an annualized excess return of 22.58%, and a recent IC of 0.1053 as of September 28, 2025[41][42] - The GAN_GRU factor's IC mean for the past year is 0.0982, with the highest IC values in the coal, building materials, social services, non-bank finance, and food & beverage industries[42][44] - The top-performing long portfolios in September 2025, based on the GAN_GRU factor, include sectors like building materials, steel, social services, coal, and non-bank finance, with excess returns of 5.78%, 5.13%, 1.91%, 1.55%, and 1.21%, respectively[45] - Over the past year, the top-performing long portfolios based on the GAN_GRU factor include home appliances, building materials, food & beverage, utilities, and textiles & apparel, with average monthly excess returns of 5.04%, 4.96%, 3.92%, 3.53%, and 3.10%, respectively[46] - The top stocks in each industry based on the GAN_GRU factor as of September 28, 2025, include companies like Baolaite, Yutaiwei-U, Cangge Mining, Tuowei Information, Hengtong Co., Angang Co., and others[49][50]
