Stocks spent most of last week in rally mode as investors largely shrugged off the coronavirus as unlikely to have a lasting negative impact on global growth.

"At least, we have an idea that the government has done a very good job at taking action and trying to contain it," said J.J. Kinahan, chief market strategist at TD Ameritrade.

Investors are looking ahead to key data releases on retail sales and consumer pricing, as well as two days of congressional testimony Powell starting Tuesday.
