Analysts estimates for Vertex now show Q3 earnings of .09/share and Q3 revenue of 334 million. What can analysts do when they have a sell/underweight/underperform rating on a stock that is exceeding expectations? No one likes to be wrong and to have to admit being wrong. But there is a way to show that you are not wrong with respect to your negative assessment of Vertex. Here is what you do: Quietly (but aggressively) raise your earnings and revenue estimates without changing your negative opinion of the stock. Then, when earnings are announced 10/27/11, you can say Vertex numbers are as expected or that they missed their numbers and came in below expectations. Being an analyst means never having to say you're sorry.
