Nasdaq falls 3.5%, S&P 500 suffers worst week since January

U.S. stocks sank Friday as investors digested two downbeat prints on the U.S. economy.

The S&P 500, Dow and Nasdaq dropped sharply following the print. The S&P 500 sank by 2.9% during the session, and by more than 5% since last Friday to post its worst weekly performance since January.

Treasury yields spiked especially on the short end of the curve, and the 2-year yield jumped to top 3%. The benchmark 10-year Treasury yield rose to more than 3.1%. U.S. crude oil prices pulled back, falling to around $120 per barrel, after rising above $122 per barrel earlier this week.
