On non-uniqueness in the option valuation problem [PDF]

arXiv
It is known that the value of a call option in the case of constant elasticity processes (CEV) with the indicator $\alpha$ exceeding the critical $\alpha=1$ is determined in a non-unique way. We show how, based on an already existing mathematical theory concerning the correctness of boundary conditions for degenerate parabolic equations on the semi ...

Asymptotic Error Distribution of the Euler Scheme for Fractional Stochastic Delay Differential Equations with Additive Noise [PDF]

arXiv
In this paper we consider the Euler scheme for a class of stochastic delay differential equations driven by a linear fractional $\alpha$-stable L\'evy motion with index $H\in(0,1)$. We establish the consistency of the scheme and study the limit distribution of the normalized error process. We show that in the rough case, i.e.

RiskMiner: Discovering Formulaic Alphas via Risk Seeking Monte Carlo Tree Search [PDF]

arXiv
The formulaic alphas are mathematical formulas that transform raw stock data into indicated signals. In the industry, a collection of formulaic alphas is combined to enhance modeling accuracy. Existing alpha mining only employs the neural network agent, unable to utilize the structural information of the solution space.

Alpha Mining and Enhancing via Warm Start Genetic Programming for Quantitative Investment [PDF]

arXiv
Traditional genetic programming (GP) often struggles in stock alpha factor discovery due to its vast search space, overwhelming computational burden, and sporadic effective alphas. We find that GP performs better when focusing on promising regions rather than random searching.

Synergistic Formulaic Alpha Generation for Quantitative Trading based on Reinforcement Learning [PDF]

arXiv
Mining of formulaic alpha factors refers to the process of discovering and developing specific factors or indicators (referred to as alpha factors) for quantitative trading in stock market. To efficiently discover alpha factors in vast search space, reinforcement learning (RL) is commonly employed. This paper proposes a method to enhance existing alpha
