Express Scripts (NASDAQ:ESRX) fell 4% today, a big fall for a $60 billion company, after it delivered its fourth-quarter earnings. While the company's revenue and adjusted earnings were just in line with expectations, and guidance landed right around what analysts were estimating, as well, the market clearly reacted today to a few disturbing trends within the company.

Revenue for ESRX has declined both year over year for the last two quarters, as well as sequentially, in three out of the past four. While the company has seen earnings per share increase, this was largely due to share buybacks, which are expected to continue. David notes that organic script growth is in decline in 2014, and in this segment from Friday's Market Checkup, he notes that he'll be digging into comments from the company regarding Obamacare, how that legislation is changing its relationships, and if the company plans to keep growing through acquisitions.
