If you're aiming to "buy low and sell high," then it makes infinite sense to start your search with bargain-priced stocks. Regularly reviewing a list of stocks trading near their 52-week lows can be a great first step.

Here, I'll try to do the initial legwork for you. To prevent us from being inundated with scores of disparate companies, I'll conduct my search by industry. This will allow us to make some initial comparisons among semi-related companies.

There are certainly some big names trading near their lows. As I warn frequently in this series, though, be careful, because many of these stocks are also trading in a tight band -- hence they're close to their highs as well.

So let's focus on valuation instead. On a P/E ratio basis, each is trading at cheap to moderate levels. And I see that each of their price-to-free cash flow ratios is roughly in line with their P/E ratios. That's a good sign.

I've written about Johnson & Johnson recently as an interesting play. Ideally, I'd like a buy-in price below $60 a share. It trades a little above that now.

As you research any of these stocks further, remember that the fear for Big Pharma is about the fading prospects for their drug pipelines. Any investment thesis should consider how effective they'll be at replenishing their blockbuster drugs once they're off patent.
