Analyzing a stock for the first time can be daunting, but one of the best ways to familiarize yourself with a new company is to crack open its latest earnings report. Take Dow component Pfizer (NYSE:PFE) as an example. Sure, it has a long history of developing new medicines and pays an attractive 3.4% yield, but is its underlying business healthy? Did its revenue grow or contract last quarter? Did any major patent expirations weigh on its total sales?

In the following video, taken from the Motley Fool's health care show Market Checkup, health care analysts David Williamson and Max Macaluso discuss Pfizer's second-quarter results and how the company stacked up against one of its big pharma peers.
