Reading these prices
The price here is the last trade on the IEX exchange before the 16:00 New York close. Shares of COST trade on many exchanges at once and IEX handles only a small slice, so the official closing price published elsewhere can differ by a few cents. IEX publishes each day's data the next day, so this page is never live.
A single day's move says little on its own: prices go up and down for many reasons, most of them short-lived. What moves markets and risk and return explain more.
