It's not really that dependent on the US economy.
They've been posting 400-600MM a quarter in free cash flow, for the last couple of years. Even in this, they are making money, and not from investments -- from their operations. Why?
Read their statements...record coal shipments and the like. Anything they lose in consumer good shipping, they gain elsewhere. They are also very good at hedging their fuel expenses.
Everyone thinks it is, yet it just keeps on rolling, year after year. Keep in mind, the Class Is all survived the great depression, too. We're not there yet
Also, the less money shippers have to throw around, the cheaper solutions they look for -- rail is the most efficient. As a result, they take some business away from air cargo and trucking operations.
Now, SIRI, is entirely dependent on people's entertainment budgets, and demand, growing, because they sure aren't making money now. Which do you think is more exposed to this economic climate?
