Precision versus Shrinkage: A Comparative Analysis of Covariance Estimation Methods for Portfolio Allocation

Sumanjay Dutta, Shashi Jain

In this paper, we perform a comprehensive study of different covariance and precision matrix estimation methods in the context of minimum variance portfolio allocation. The set of…

Prediction of drag components on rough surfaces using effective models

Sahaj Jain, Y. Sudhakar

Owing to the multiscale nature and the consequent high computational cost associated with simulations of flows over rough surfaces, effective models are being developed as a practi…

A semi-static replication approach to efficient hedging and pricing of callable IR derivatives

Jori Hoencamp, Shashi Jain, Drona Kandhai

We present a semi-static hedging algorithm for callable interest rate derivatives under an affine, multi-factor term-structure model. With a traditional dynamic hedge, the replicat…

Method of lines for valuation and sensitivities of Bermudan options

Purba Banerjee, Vasudeva Murthy, Shashi Jain

In this paper, we present a computationally efficient technique based on the \emph{Method of Lines} (MOL) for the approximation of the Bermudan option values via the associated par…

Neural network for pricing and universal static hedging of contingent claims

Vikranth Lokeshwar, Vikram Bhardawaj, Shashi Jain

We present here a regress later based Monte Carlo approach that uses neural networks for pricing high-dimensional contingent claims. The choice of specific architecture of the neur…
