So why did it move?
Our data can't say. It shows what was published and what changed in the numbers, but a reason needs a source, and a move can also come from news, analyst views or trading across the market that our data doesn't cover.
What does it mean?
A day's moves describe the past. They don't tell you where prices go next, and our own tests found our scores have not reliably picked future winners.
