Determination of the premium for buy-back in companies in emerging markets

These data are used in a study of the effect of buybacks on stock prices. The study obtained evidence of a positive market reaction to the announcement of a buyback in various event windows. It also revealed a negative relationship between cumulative excess returns and indicators such as: size of the company and return on free cash. The share-buyback ratio, in contrast, showed a positive correlation with cumulative excess returns. In addition to the confirmed hypotheses, two were rejected: IT sector companies have a higher premium over the price, and the size of the premium has a positive effect on the growth of stock prices. Also this data helps to make regression and logit models of price changing.
