To consider capital as a call option over a firm’s assets, has allowed the development of a set of dynamic models to predict corporate financial distress and bankruptcy. Nevertheless, a downside of the above mention assumption derives from the direct and positive relationship between the capital value (prime) and the asset´s underlying volatility. This reasoning implies that the greater the risk of a firm, the larger its value has to be, leading to an inconsistency in the logic used to estimate financial distress and bankruptcy probability. An alternative approach to predict financial distress and banckruptcy is the use of exotic barrier options because its structure fits better the firm´s value–volatily relationship. Based on the existing literature, this paper proposes a “naive” barrier option model, since it simplifies the estimation of the unobservable variables such as: firm asset´s value and risk. This article is structured as follows: first, simple call option and barrier option models were developed in order to estimate the firm´s capital value and the financial distress and bankruptcy probability. Using a hypothetical case, a sensitivity analysis over volatility and time to maturity was carried out. A similar application was used to estimate the firm´s capital value and the financial distress and bankruptcy probability in two Argentinian capital firms, each with a different degree of leverage: Yacimientos Petrolíferos Fiscales S.A (YPF) and Aluar S.A (ALUAR). The analysis confirmed the consistency in the relationship volatility-valuefinancial distress probability of the proposed model. Finally, the main conclusions are drawn
