In this research methods of textual processing and web scraping were developed, were collected journalistic articles from the specialized media channels and processed to obtain three types of variables: textual complexity, textual sentiment, and media attention. The results found are: less complex news are related to higher trading volumes and higher corporate investments, the effect of the news sentiment is very short term and the news complexity affects the speed of market information diffusion for longer periods. Other results are: the corporate investment is directly related to the sentiment of the news published right before the spending is carried out, for older news the effect is the opposite, old bad news are related to biggest corporate investments, was also observed that media attention is related to higher volumes traded and higher absolute values of corporate investment, however, media attention showed an inverse relationship with corporate investment calculated as a percentage of company assets, indicating that firm size is related to the amount of news published in specialized media.
