When there is unexpected news in the market, the market is more likely to:Become more volatileRemain unchangedShut down

When unexpected news hits the market, the typical reaction is that the market becomes more volatile. This volatility arises because investors react to the news with uncertainty and adjust their positions, leading to increased buying and selling activity. The sudden influx of trades based on new information drives price fluctuations, as market participants reassess the value of assets based on the latest developments.

In contrast, the market is unlikely to remain unchanged, as new information typically disrupts the existing equilibrium. Shutting down the market is also not a common reaction; while this can happen in extreme circumstances (such as during a severe crisis), it is not a typical response to unexpected news. Thus, the most accurate response is that the market becomes more volatile in reaction to unexpected news.
