Frequently Asked Questions

Q.Why did the S&P 500 not move on Thursday despite big news?

The S&P 500 ended Thursday almost exactly where it closed Wednesday, even though there were plenty of reasons for a big move. One specific factor may have been partly responsible for keeping the index pinned, according to analysts.

Q.What does it mean when the S&P 500 closes flat after a major news day?

A flat close after high-profile catalysts suggests that market forces may have been offsetting each other, or that a structural factor was suppressing volatility and keeping prices range-bound.

Q.How unusual is it for the S&P 500 to barely move when major events are happening?
