- Abstract: The existing publications demonstrate that the limit order book data is
useful in predicting short-term volatility in stock markets. Since stocks are
not independent, changes on one stock can also impact other related stocks. In
this paper, we are interested in forecasting short-term realized volatility in
a multivariate approach based on limit order book data and relational data. To
achieve this goal, we introduce Graph Transformer Network for Volatility
Forecasting. The model allows to combine limit order book features and an
unlimited number of temporal and cross-sectional relations from different
sources. Through experiments based on about 500 stocks from S&P 500 index, we
find a better performance for our model than for other benchmarks.

Multi-Step Regression Stock Price Prediction [54.21695754082441]
Multi-step stock price prediction over a long-term horizon is crucial for forecasting its volatility.
Current solutions to multi-step stock price prediction are mostly designed for single-step, classification-based predictions.
We combine a deep hierarchical variational-autoencoder (VAE) and diffusion probabilistic techniques to do seq2seq stock prediction.
Our model is shown to outperform state-of-the-art solutions in terms of its prediction accuracy and variance.

Concept-Oriented Shared Information [73.40830291141035]
Several methods were recently proposed to mine the shared information through stock concepts extracted from the Web to improve the forecasting results.
Previous work assumes the connections between stocks and concepts are stationary, and neglects the dynamic relevance between stocks and concepts.
We propose a novel stock trend forecasting framework that can adequately mine the concept-oriented shared information from predefined concepts and hidden concepts.

Deep learning models have led to significant performance improvements in many problems coming from different domains, including prediction problems of financial time-series data.
The Temporal Attention-Augmented Bilinear network was recently proposed as an efficient and high-performing model for Limit Order Book time-series forecasting.

We propose a relational event-driven stock trend forecasting (REST) framework, which can address the shortcoming of existing methods.
To remedy the first shortcoming, we propose to model the stock context and learn the effect of event information on the stocks under different contexts.
To address the second shortcoming, we construct a stock graph and design a new propagation layer to propagate the effect of event information from related stocks.
