Leucadia National (NYSE: LUK) is a difficult business for many investors to understand. The combination of the Jefferies Group financial services company, the National Beef meat processing and supply company, and plenty of other smaller investments present a challenge for those seeking to know the ins and outs of what affects Leucadia’s results. In general, though, conditions in the financial industry have been more volatile than the rest of the business, and Jefferies, therefore, plays a bigger role in how the overall company does.
