Pricing Features

Pricing Main Features Support for all types of CME, OTC vanilla and exotic derivatives. User can design own pay off function Full support for the delivery of real time prices for futures and options including optional real-time YellowJacket® interface Hourly & Daily compound indices on any weather elements Support for any combination of derivatives as a strip (multi year, multi month, flexi, etc…) Many statistical methods to detrend the data, fit distributions, perform Monte Carlo simulations Full back and middle office module Full weather data and forecast data management on own database

Speedwell Weather System Pricing Features A range of index types, weather references and option periods are available. Single, Compound and Hourly Indices can be calculated, allowing the additional use of Spreads and Baskets Specify Models at the Index, Option and Portfolio level to specifically tailor index, option and Portfolio pricing methods Large range of standard index and option types. Facility to create your own option type Partial Indexing can be used to price structures that need to be priced within the index period View the historical payoff and final index values for each historical option period for all the available years of data here Option to exclude all days of a week AND specific days (e.g. bank holidays) Explicit support for uncapped structures

Speedwell Weather System Pricing Features SWS allows the trader to easily see the impact of different periods on burns and the impact of different detrending methods on pricing

Speedwell Weather System Forecast Integration Portfolio Forecast Impact Analysis View the impact of multiple forecasts on pricing Ensemble Forecasts (unlimited number of members) and deterministic forecasts from multiple suppliers are fully integrated into pricing and risk management in SWS. Prices and portfolio valuations can be seen with and without forecasts. In the case of ensemble forecasts, the average, median, worst or best case can be selected. A structure can also be priced SEPARATELY using EVERY single ensemble to correctly capture outliers (important with convex structures such as options, critical day structures, vanillas in the shoulder months) Shown above are two tools that are used to examine the marginal impact of forecasts on pricing an individual option or portfolio. All forecasts are persisted allowing for retrospective portfolio valuations and allowing for independent skill scoring. It is also easy to render forecasts graphically

Speedwell Weather System Forecast Visualisation in SWS View Multi-Member Ensemble Forecasts as path plots View Multi-Member Ensemble Forecasts as box-plots with average and N-years’ climatology overlaid Compare successive forecasts sequentially. This can also be done for forecasts issued on a given day by multiple suppliers Seasonal and monthly ensemble forecasts are also supported. Shown here are the average and 10 year climatology.

Speedwell Weather System Forecast Viewing: Probability Distribution Graphs Probability Distribution Functions of ensemble forecasts can now be viewed within SWS. This allows the nature of the distribution and the evolution of uncertainty over time to be visualised graphically. The width of the curves exhibited are good indicators of the likelihood of the forecast outcomes – the forecast confidence for each day can be inferred from this. These curves can also be helpful for identifying when ensemble forecasts predict two or more likely outcomes i.e. a bi-modal distribution which information is lost in a deterministic forecast

Speedwell Weather System Hourly Index Pricing Hourly Indices can be created on both single and compound indices. This allows for support of complex structures including the Schiphol critical hourly based structure Hourly index parameters are easy to configure: the required hours of the deal, an index on the hourly data points and the possibility to transform to a daily index. Hourly Intervals can even be used to form indices on irregular intervals such as half hourly or quarter hourly periods

Speedwell Weather System Strip Creation and Pricing The Weather Derivatives Wizard enables quick and easy formation of strips and includes specification of overall negative and positive caps The pricing of the strip and the component options are shown with separate burn analyses here Strip pricing analysis also compares the historical and simulated values graphically and gives all the relevant pricing information in this view
