What these figures are

Each tile shows a sector fund's move, with the symbol named on it, because a fund is weighted by company size. That is what "how did technology do today" usually means. Open a sector and you get a different figure beside it: the median company's move among the large names listed there, counted equally. The two will not match, and the gap between them is worth reading. A sector can rise on one enormous company while most of its names fall.

Over a day the change is measured from the previous close. Over a longer window it is measured from the first price in that window, so the year-to-date figure starts at the first trading day of the year rather than at midnight on the first.

The company lists behind each sector are a selection of large US-listed names, not the whole sector and not an index's membership. Companies join and leave real indices constantly; those lists do not track that.
