Ben Brooks is spot on, as usual:

Given that definition, why are stories worded: “Company A missed expectations”? Shouldn’t the correct wording be: “Analyst John posted a bad guidance”? Of course it should be, but no one actually cares about that analyst’s ability to predict the future, because trying predicting the future is futile. So instead we look at who failed to meet a goal set by a person with a business card that reads “analyst”.

Today, Apple posted the largest corporate earnings in the history of American business. The stock is down 10% in after hours trading.

Sometimes the world just doesn't make a lot of sense, does it?
