- Abstract: Measuring risk is at the center of modern financial risk management. As the
world economy is becoming more complex and standard modeling assumptions are
violated, the advanced artificial intelligence solutions may provide the right
tools to analyze the global market. In this paper, we provide a novel approach
for measuring market risk called Encoded Value-at-Risk (Encoded VaR), which is
based on a type of artificial neural network, called Variational Auto-encoders
(VAEs). Encoded VaR is a generative model which can be used to reproduce market
scenarios from a range of historical cross-sectional stock returns, while
increasing the signal-to-noise ratio present in the financial data, and
learning the dependency structure of the market without any assumptions about
the joint distribution of stock returns. We compare Encoded VaR out-of-sample
results with eleven other methods and show that it is competitive to many other
well-known VaR algorithms presented in the literature.

- Bridging Econometrics and AI: VaR Estimation via Reinforcement Learning and GARCH Models [0.0]
We propose a hybrid framework for Value-at-Risk (VaR) estimation, combining GARCH volatility models with deep reinforcement learning.
Our approach incorporates directional market forecasting using the Double Deep Q-Network (DDQN) model, treating the task as an imbalanced classification problem.
Empirical validation on daily Eurostoxx 50 data covering periods of crisis and high volatility shows a significant improvement in the accuracy of VaR estimates.

Construction [4.059196561157555]
Many existing prediction approaches focus on single-point predictions, lacking the depth needed for effective decision-making.
We propose RAGIC, which introduces sequence generation for stock interval prediction to quantify uncertainty more effectively.
RAGIC's generator includes a risk module, capturing the risk perception of informed investors, and a temporal module, accounting for historical price trends and seasonality.

Historical simulation (HS) uses the empirical distribution of daily returns in a historical window as the forecast distribution of risk factor returns in the next day.
HS, GARCH and CWGAN models are tested on both historical USD yield curve data and additional data simulated from GARCH and CIR processes.
The study shows that top performing models are HS, GARCH and CWGAN models.

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.

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.
