SAN FRANCISCO (Reuters) - The S&P 500 suffered its worst day in two years on Monday as a surge in coronavirus cases outside China rattled investors already worried about valuations following recent record highs.
The S&P 500's 3.35% slump was the leading U.S. stock index's deepest one-day loss since February 2018, when Wall Street was in a correction.
The fear in Monday's session came after investors in recent months often downplayed the overall risk related to the new coronavirus. Monday's drop wiped out all of the S&P 500's gains for 2020.
"With stock prices and valuations still near cycle highs, the risk of a worsening virus outbreak has not been priced into the market to a great extent," Truist/SunTrust Advisory Chief Market Strategist Keith Lerner wrote in a client note.
S&P 500 sector indexes are mostly still close to their record highs, with the exception of energy (SPNY). The S&P information technology index (SPLRCT) tumbled 4.2% on Monday, slammed by losses for chipmakers and Apple (O:AAPL), which rely more than most other U.S. companies on China. The information technology index is down over 7% from its record high on Feb 19, but remains up almost 4% in 2020.

Increased fears that the coronavirus could become a pandemic led to a spike in the number of listings on the New York Stock Exchange hitting 52-week lows. At 503, Monday saw the greatest number of new lows in a session since last August. At the same time, the number of stocks hitting 52-week highs shrank to 278 from over 400 on Friday.
