We all hear about the massive fluctuations of the stock market due to fears and responses to the coronavirus pandemic. The market also has also triggered "circuit breakers" that temporarily halt trading to prevent massive swings.
What could potentially happen if they just halted all trading for the next two months as a medium-term circuit breaker? Assume they did it at night without warning so that people couldn't get trades in before the closure. Would the rest of the economy continue to function otherwise (other coronavirus effects not withstanding)? During the closure, I would imagine that stock prices would just stay the same and then companies would adapt to their changing supply and demand situation as needed, right?
Once it opened again there might be a swing once we know which companies have survived the pandemic and which won't but that speculation is happening on a daily basis now, why not just close it to prevent chaos and allow companies to think longer term without worrying about momentary market valuation?
