What moved today, and why?

How to read this page
How it’s measured. S&P 500 and Nasdaq-100 stocks. A normal day is the stock’s average true range over the last 14 days.
Sources. Daily prices from Financial Modeling Prep.
Why splits each move three ways: the S&P 500’s move, the extra move of the stock’s group, and what is left for the company alone. The largest part in the direction of the move gives the label.
In our research, big one-day drops have not reliably bounced back, and big gains have not reliably reversed. A large move describes today; it is not a signal on its own.
