  • Stocks have rallied this week after China's rebounding stock market sent a positive message to global markets, but analysts caution there's still a long way to go with the potential impact of the coronavirus.
  • Part of the reason for the rally has been the backstop of liquidity provided by the People's Bank of China, and investors are betting the Federal Reserve would also be ready to cut rates again if the virus hurts the U.S. economy.
  • Analysts say stocks were also helped by the fact that there was no clear front runner in the Iowa Democratic caucuses Monday, and the progressive candidate, Vermont Sen. Bernie Sanders, came in second behind Pete Buttigieg.

Analysts caution there's likely to be more negative headlines on the spread of coronavirus as well as a deeper economic hit to the Chinese economy, but they also say any further impact could also be cushioned by central banks.

"The news is going to get worse, but you have to juxtapose that against the stimulus response. That's what we're living through right now," said Art Hogan, chief market strategist at National Securities. "You don't know how long China is going to be closed. You have to make a guess about how much of that activity does not get caught back up ... It hits us in multiple ways."
