A call option gives its owner the right to purchase an underlying asset at a specified price and at a specific time. A put option gives its owner the right to sell the underlying asset at […]
Exploring Open Interest for Futures Contracts with R
In this article we will explore in greater depth the Open Interest variable of the futures contracts price data and see in which months of the year this variable tends to increase for a particular contract. For this purpose, we have gathered contracts futures data from CSI 500 Shanghai Index. Our task will be to […]
Contango and Backwardation
The concepts of Contango and Backwardation are related with the term structure of the futures contracts. During the life of a contract, the difference between the futures price and the expected future price is called basis. At the end of the contract’s life, the futures price converges to the expected future spot price. Each month, […]
Creating Term Structure of Futures Contracts Using R
The terms structure of the futures contracts for a specific asset is generated by the contracts prices at different expiration times. The contracts have different prices on each expiration date and there is an underlying relationship between them that is reflected with different shapes. The most common shapes are called normal or inverted forms. These […]
