The identification of the forces that drive oil stock prices is extremely important given the size of the Oil&Gas industry and its links with the energy sector and the environment. In the next decade oil companies will have to deal with international policies to contrast climate change. This issue is likely to affect companies' shareholder values.

We study the issuance and payout policy that maximizes the value of a firm facing both agency costs of free cash-flow and external financing costs. We find that firms have target cash levels and optimally issue equity when they run out of cash. We characterize the process modelling the number of outstanding shares and the dynamics of the stock prices. In line with the leverage effect identified...

We examine the impact of share repurchases on the information content of stock prices using several measures of price efficiency. The study is based on manually collected data on share repurchases in the United States for the period 2004-2010. We find that share repurchases make prices more efficient. In particular, share repurchases increase the accuracy of the stock price after negative infor...

We consider the linkage between stock prices and exchange rates in four Middle East emerging markets.
