      Sentiment is, by definition, opinion. It is not a fact, but ratherwhat people think. Sentiment is based on all of the information or inputthat was used to make the decision to buy, sell, or do nothing at all. Thewidely held belief is that all available public information is representedin the price of a stock, and thus, the value of the stock is representativeof the interpreted meaning and value of all available public information.
