re: Am I the only one who thinks the market's reaction to the coronavirus outbreak is...

The Hong Kong stock market has been open this week. Shanghai has been closed. But in Shanghai's last day of trading, 1/23/20, it was down almost 3%. So there was some selling already there before the holiday began.

I would expect the Shanghai market to react to the virus outbreak in China since China seems to be the epicenter of the outbreak. Its economy and supply chains will most likely be the most affected by travel restrictions inside the country.

So, yeah, a stock market pullback there would not be surprising.
