For today's pick, I opened up the railroad industry.  This was a small set, with only ten stocks for scrutiny.  I selected CP as the best bet out of those ten.

CP has the second-smallest market cap at $9.98B, which is about half the cap of eight of the other railroads in this group.  The smallest market cap is GWR at $791.36M.  Small caps have more room to grow in general, so it came down to a choice between CP and GWR.

CP has a lower P/E ratio and higher profitability than GWR, and that's all there is to it.  With greater growth potential and more money available for operations, CP is a better bet.  Out of all ten public railroad companies, this is the one to buy.
