No, this is not considered communication. If right before measuring the particle one side gets a new information that e.g. selling the Microsoft stock right now is a really bad idea, they have no way to communicate this information to the other. Both of them will take a synchronized action, but synchronized according to the rules they have agreed on previously. They cannot use entanglement to transmit new information from one side to the other. They can only use it to receive the same random data at the same time, which they can use to take a coordinated action.
