Any model that incorporates a binomial tree, also called a binomial lattice. A binomial model describes the evolution of a random variable over a series of time steps, assigning given probabilities to a rise or fall in the variable.
After the initial rise or fall, the next two branches will each have two possible outcomes, so the process will continue, building a ‘tree’ over time. The process is usually specified, so that an upward movement followed by a downward movement results in the same price, so the branches recombine.
Binomial trees are of interest because they can be used to deal with American-style features; the early-exercise condition can be tested at each point in the tree.
Commodity trading and risk management is a subject that is necessarily complicated, and is becoming more so. The Energy Risk Glossary seeks to disentangle and clarify the jargon by providing definitions of commonly used energy and commodity market terms.
These include definitions related to a variety of underlying energy products, as well as technical terms about the many instruments and benchmarks used by energy market participants.
Many of the most recent terms to have been added to our glossary stem from the actions of regulators since the 2008 global financial crisis. The onset of rules, such as the US Dodd-Frank Act and European Market Infrastructure Regulation, has markedly increased the cost and complexity associated with commodity trading. Perhaps they have also increased the need for a handy reference guide such as this.
The glossary is extensively cross-referenced, making for easy and thorough searches. We hope you find the latest edition of the Energy Risk Glossary to be a useful resource.
