It's been a little over a month since I made the latest edition to the Real-Money Stock Portfolio I manage for Fool.com, so I'm back on the hunt. And although there aren't nearly as many values out there amid today's increasingly expensive markets, I've found a few more amazing companies I'll be adding over the next several days to my defensive value-investing portfolio. The first of which is East Coast railroad powerhouse CSX (CSX -0.12%), which still looks like a great value today.

In an industry with some pretty impressive tailwinds, CSX stands as one of the best companies. Among the many reasons I love it are its location as a key go-between among many of the country's most critical economic areas, the efficiency improvements that should continue for years to come, and its payout prowess. In the video below, I break down in greater detail why I want to own CSX today.
