For our experiment we picked a research period of Oct. 26 to Nov. 28, 2005, to gather news articles and stock quotes.We further focused our attention only on companies listed in the S&P 500 as of Oct. 3, 2005.We acknowledge that several mergers and acquisitions did take place during this period of time; however, this only had an effect on less than 2% of the stocks tracked. In order to eliminate the “company in passing” problem, we gathered the news articles from Yahoo Finance using a company’s stock ticker symbol.
