Answer:
The correct answer is: A bear market.
Step-by-step explanation:
AT&T stock is included in the NYSE (New York Stock Exchange) index, which is a composite of all listed stocks that trade in that exchange. It is considered to be one of the most accurate indexes there are since it includes all the stocks listed in that exchange instead of a portion of them such as the S&P 500, for instance. If the stock of AT&T has been falling for months, it is highly possible that the overall market is on the red, what investors call "Bear Market".
