Why it matters: The coronavirus could drastically affect markets if consumers refrain from travel. Companies that rely on tourism including airlines and resorts were hit especially hard Monday. The sell-off marked the Dow's first five-day losing streak since August, AP reports. It was also the S&P 500's worst day since October.
