Sometimes I am surprised to find huge differences between data given by YahooFinance and those given by Reuters. These differences appear mainly in the figures of "Growth Estimates: Next 5 years (per annum)". An example: the data that Yahoo gives for Yandex (YNDX) is 0.53%, while according to Reuters it is 30.80%. I also find great differences in the data of the same company depending on where it is listed. Example: The figures that Yahoo gives for ArcelorMittal’s Growth Estimates “Past 5-years (per annum)”: 31.33% (in NYSE), 65.65% (in Madrid), 49.76% (in Milan), 58.83% (in Amsterdam). And even greater differences appear for its “Next 5-years (per annum)”: 5.94% (in NYSE), 64.31% (in Madrid), 7.10% (in Milan), 15.34% (in Amsterdam).
