Stocks were choppy for most of Thursday's session as investors mulled over the latest inflation data. However, the main benchmarks took a sharp turn lower in afternoon trading as Treasury yields spiked.  

Ahead of the open, data from the Bureau of Labor Statistics showed that the September Consumer Price Index (CPI) was up 0.4% month-over-month and 3.7% year-over-year. While these figures were higher than economists were expecting, the monthly increase was slower than what was seen in August, while the annual rise was unchanged.
