From quarterly data for the market value of equity ( equity ) and Enterprise Value ( market value of the company ) of publicly traded companies in the food and beverage sector listed on the Bovespa, this paper examines how the economic instability period 2002-2012 impacted the value of selected companies. Specifically, we selected a sample of four (4) companies: AMBEV, BRFoods, Bread-cane group and Agro Rasip during that period to these two variables, an autoregressive model was applied with endogenous threshold value in order to capture changes of regime in dynamics described by the value of these companies as well as to describe the stochastic process described by for variables selected in period abovementioned. Quantitative indicators for these variables were then calculated and the methodology allowed to investigate the linearity and stationarity of their trajectories, producing results that revealed different situations for companies in its two variables: i) value of equity and enterprise value of AmBev and BRFoods showed linear dynamic with explosive tendencies; ii) the value of Bread-cane group presented a nonlinear dynamic and explosive unit root trend, but the value of Equity presented nonlinear dynamics and partial unit root with endogenous estimated value threshold of 5.89; iii) The Rasip Agro introduced nonlinear dynamics and partial unit roots with stationary above the estimated threshold. Together, these findings suggest that although be they of essential goods sector enterprises, economic instability impacted differently on the value of firms. The economic size of AmBev and BRFoods is natural cause of no regime change in dynamic of its value, and the fact that these companies are less subject to idiosyncratic shocks.
