Abstract

This study analyzed the soybean agribusiness in the Brazilian Western Central as the exposure to price risk and the financial performance of the leading companies in the production chain. Specifically, calculated the hedge effectiveness for soybean futures contracts traded on the CME Group maturing in March, for the period 2004 to 2013. Also, compared the efficiency of the main companies in the Brazilian Western Central, classified in ranking, and examined the financial performance in qualitative analysis of the reports. To calculate the hedge effectiveness, applied four great reason methods to build portfolios, the simple or naîve, static, static with error correction (ECM) and dynamic GARCH-BEKK. For spot prices, chosen the municipalities with higher production in each state, Sorriso in Mato Grosso state, Rio Verde in Goiás state and Maracaju in state of Mato Grosso do Sul. For analysis of efficiency and financial performance used the Data Envelopment Analysis method - DEA and the structure of traditional ROA DuPont formula, classifying the performance in rankings and reporting the qualitative analysis from the notes. The sample for performance analysis were eight companies chosen from Melhores & Melhores, anual report from EXAME magazine, year 2013. Used data from 2011 to 2013. Among the findings, concluded that the soybean futures contracts traded at CME Group maturing in March expressed low efficiency to reduce the variance of portfolios. Concerning the financial performance, Coamo and Cargill were in the positive spectrum of the sample and Caramuru and Louis Dreyfus expressed unfavorable performance.
