In an already massive market segment, are dividends all you can hope for when you hunt down "elephants" like Warren Buffett does? While you probably won't get a five-bagger at this level, seeing a price increase in the 20%-50% range is very possible. In the case of stock splits, you may very well see adjusted share prices rise considerably. Plus, there's always the prospect of a company's stock becoming exceedingly popular and breaking the normal rule of staying under $200 a share the way Google Inc (NASDAQ: GOOG ) and Apple Inc. (NASDAQ: AAPL ) have. Let's take a look at some of the biggest drug stocks on the planet and see if they've got any juice left in them. Can a titan hit a growth spurt? With a $240 billion market cap, they don't come much bigger than Johnson & Johnson (NYSE: JNJ ). One reason I like J&J is that despite being the kind of company people are always using to compare to others because of its stability, it's only trading for around 23 times its earnings.
