Performance analysis derivative based updating method
A weighting factor may also be calculated for a set of analysts based upon factors such as the recency of an analyst's earnings estimates. 23, 1999, entitled “Security Analyst Performance Tracking and Analysis System and Method,” which claims priority to U. The role of the security analyst is generally well-known and includes, among other things, the issuance of earnings or other financial estimates concerning future economic events and recommendations on whether investors should buy, sell, or hold financial instruments, such as equity securities.Using these adjustment and weighting factors and each analyst's actual earnings estimate, a custom composite estimate may be derived. Security analyst estimates may include, but are not limited to, quarterly and annual earnings estimates for companies, whether or not they are traded on a public securities exchange.As a result of price adjustments, cash flow may be generated between buyers and sellers.The derivative product may pay a predetermined final settlement amount or percentage upon the triggering of a predetermined event.

These methods were pioneered by Hooke and Jeeves .The estimated performance level of a performance characteristic is determined for the particular crop associated with at least a portion of the defined geographic area based upon the evaluation.evaluating at least one of the obtained weather data, the obtained soil data, and the obtained management data in comparison to reference weather data, reference soil data, and reference management data;identifying preferential growing locations for growing a particular crop in the defined geographic area based on the estimated agronomic performance level meeting or exceeding a benchmark performance level or maximizing the expression of a genetic trait of a crop, without any estimation of potential economic profit or loss for growing the particular crop; andgenerating a list of preferential growers associated with the preferential growing locations for marketing seed or a crop precursor for the particular crop based on correlating or matching location data extracted from marketing data to the preferential growing locations. 31, 2003, and entitled METHOD AND SYSTEM OF EVALUATING PERFORMANCE OF A CROP, under 35 U. The seed developers may test the performance of the crops and underlying seeds at test sites.wherein the evaluating comprises classifying at least one of the obtained weather data, the obtained soil data, and the obtained management data with reference to corresponding critical attributes and associated critical attribute values of the reference weather data, reference soil data, and reference management data.determining a benchmark performance level for the performance characteristic for the particular crop based upon at least one of the reference weather data, the reference soil data, and the reference management data. However, if the test sites are not representative of the environmental conditions of a particular grower's land or the intended planting site, the performance tests of the developer may not provide reliable or applicable test results.A front-end graphical user interface (GUI) is used to view analyst historical data either as raw data or, by using a data visualization technique, as a graph or chart.a user interface for selecting criteria, including one or more of a time frame over which earnings predictions are to be measured; a number of periods over which to measure performance; at least one error metric to be used to calculate performance; one or more securities over which to measure performance; and exclusion criteria by which to exclude certain earnings predictions; and a processor for determining performance based on the selected criteria and the historical data. A computer-implemented method of objectively measuring security analysts' performance based on historical accuracy of their earnings predictions for one or more securities, the method comprising the steps of: selecting criteria via a user interface, including one or more of a time frame over which earnings predictions are to be measured; a number of periods over which to measure performance; at least one error metric to be used to calculate performance; one or more securities over which to measure performance; and exclusion criteria by which to exclude certain earnings predictions; and This application is a divisional of co-pending U. At least some investors tend to rely on the earnings estimates and recommendations issued by security analysts.Usually more than one analyst follows a given equity security.
