What is Assume?
Assume is when you take something to be true, without any proof of its truth. Assumptions play a key part in an analyst day-to-day. Generally, assumptions are followed by evidence, that either validate or nullify the assumption. For example, an Analyst may assume that the price of a stock will increase tomorrow. If the price does go up then, his assumption has been validated and was correct, if the price of the stock stays the same or decreases then his assumption was incorrect and wrong.
