Persistence as an Optimal Hedging Strategy. [PDF]
Biophys J, 2021 Abstract Bacteria invest in a slow-growing subpopulation, called persisters, to ensure survival in the face of uncertainty. This hedging strategy is remarkably similar to financial hedging, where diversifying an investment portfolio protects against economic uncertainty. We provide a new theoretical foundation for understanding cellular

Journal of Asian Security and International Affairs, 2022 The aim of this text was to evaluate Mongolian foreign policy by applying the hedging strategy. We have arrived at the conclusion that the way Mongolia strives to secure itself against insecurities and risks in the fast-changing environment of East Asia corresponds to main principles of the hedging strategy and in basic outlines that it is not ...

Serotoninergic Modulation of Phototactic Variability Underpins a Bet-Hedging Strategy in Drosophila melanogaster [PDF]
Frontiers in Behavioral Neuroscience, 2021 When organisms’ environmental conditions vary unpredictably in time, it can be advantageous for individuals to hedge their phenotypic bets. It has been shown that a bet-hedging strategy possibly underlies the high inter-individual diversity of ...

Bayesian Inference for Optimal Risk Hedging Strategy Using Put Options With Stock Liquidity
IEEE Access, 2019 This paper considers the problem of hedging the risk exposure to imperfectly liquid stock by investing in put options. In an incomplete market, we firstly obtain a closed-form pricing formula of the European put option with liquidity-adjustment by ...

Perspectives on Serbia’s China–EU Hedging Strategy: Resilient to De-hedging? [PDF]
Međunarodni ProblemiIn an increasingly multipolar international system, small states like Serbia exert complex strategic dilemmas in navigating great power competition. This paper investigates Serbia's hedging strategy between its two main poles of foreign policy preference—

Bet-hedging strategies in expanding populations.
PLoS Computational Biology, 2019 In ecology, species can mitigate their extinction risks in uncertain environments by diversifying individual phenotypes. This observation is quantified by the theory of bet-hedging, which provides a reason for the degree of phenotypic diversity observed ...

Empirical Evidence of a Bet‐Hedging Strategy in the Carrot Cyst Nematode Heterodera carotae [PDF]
Ecology and EvolutionBet‐hedging is an evolutionary strategy encountered in several plant and animal species that allows minimizing the risks by sacrificing mean fitness for a reduction in temporal fitness variation.

Gamma and vega hedging using deep distributional reinforcement learning
Frontiers in Artificial Intelligence, 2023 We show how reinforcement learning can be used in conjunction with quantile regression to develop a hedging strategy for a trader responsible for derivatives that arrive stochastically and depend on a single underlying asset.

Tractable hedging: An implementation of robust hedging strategies [PDF]
Journal of Economic Dynamics and Control, 2004 This paper provides a theoretical and numerical analysis of robust hedging strategies in a diffusion-type setup including stochastic volatility models. A hedging strategy is called robust if the hedger achieves an overprotection whenever the realised volatility stays within a given interval.
