- Abstract: The paper proposes a new asset pricing model -- the News Embedding UMAP
Selection (NEUS) model, to explain and predict the stock returns based on the
financial news. Using a combination of various machine learning algorithms, we
first derive a company embedding vector for each basis asset from the financial
news. Then we obtain a collection of the basis assets based on their company
embedding. After that for each stock, we select the basis assets to explain and
predict the stock return with high-dimensional statistical methods. The new
model is shown to have a significantly better fitting and prediction power than
the Fama-French 5-factor model.

It is still an open question to build a factor model that can conduct stock prediction in an online and adaptive setting.
We propose the first deep learning based online and adaptive factor model, HireVAE, at the core of which is a hierarchical latent space that embeds the relationship between the market situation and stock-wise latent factors.
Across four commonly used real stock market benchmarks, the proposed HireVAE demonstrate superior performance in terms of active returns over previous methods.
