基于粗糙路径签名的奇异衍生品无模型定价的数值方法

Numerical method for model-free pricing of exotic derivatives using rough path signatures

Terry Lyons, Sina Nejad, Imanol Perez Arribas

摘要:

我们估计价格的异国情调的期权在离散时间无模型设置时,交易者有机会获得市场价格的一个足够丰富的类异国情调和香草期权。这是通过估计一个不可观察的数量称为“隐含预期签名”从这样的市场价格,这是用来定价其他外来衍生品。隐含的预期签名是表征市场动态的对象。

英文摘要:

We estimate prices of exotic options in a discrete-time model-free setting when the trader has access to market prices of a rich enough class of exotic and vanilla options. This is achieved by estimating an unobservable quantity called "implied expected signature" from such market prices, which are used to price other exotic derivatives. The implied expected signature is an object that characterises the market dynamics.
