The performance of various sectors of the economy over time is subject to a number of interferences and influences that determine the dynamics of their evolution, through moments of great euphoria at one extreme, the other a deep recession and stagnation. Knowing that the stock market functions as a true indicator of these changes, this study aimed to investigate evidence that could characterize the occurrence of a process of formation of prices bubble in stock market. For this, the study was the analysis of historical prices of stocks and their dividends from the civil construction companies present in Brazil's BM&F Bovespa. Statistical analysis showed that the values studied quotations, in most cases, present a high level of dispersion and expected returns of these stocks are distributed in a uniform percentage range nothing. From the econometric point of view, the study employed co-integration tests for time series analysis of variables, concluding that more than half of the sample data has no co-integration, the possibility of revealing the presence of a speculative component. Given the disparity of data, the paper contends, in this way, the Brazilian civil construction sector has component bubble in their stock prices.Downloads
