Today's move, what drove it, and what the available information cannot explain.
Capitalisation weighted, so a move in the largest companies moves it more than a move in the smallest.
Every Nasdaq listing, weighted by capitalisation and heavy in technology.
Thirty names weighted by price rather than by capitalisation, so it can disagree with the S&P for arithmetic reasons alone.
Small capitalisation names. Read against the S&P, it is the size half of how broad a day was.
The same five hundred companies weighted equally, so the largest names count no more than the smallest. Read against the cap-weighted index, the gap is how much of the day belonged to the biggest companies.
The equal-weighted index outran the cap-weighted one, so the session was broader than the headline index makes it look.

Counted over ^GSPC, ^IXIC, ^DJI, ^RUT, ^FTSE, ^N225, ^GDAXI, 000001.SS. This is a reading across whole market indices, not a count of the companies inside any one of them.

Expected thirty day volatility from S&P 500 options. Rising with the index is the contradiction worth seeing.

Built in code from the movers whose evidence did not resolve, so no written summary can shorten this list.
The S&P 500 rose 0.33% while the equal weight fund rose 1.37%, a gap of 1.05 points, pointing to gains spread more broadly than the headline index alone suggests.
Dow rose 1.08% and Russell 2000 rose 1.38%, both well ahead of Nasdaq's 0.08% gain, a split suggesting broader and smaller-cap exposure outpaced large-cap growth names.
Sector returns ranged from Health Care up 1.86% to Energy down 1.58%, a wide spread beneath a headline index gain of only a third of a percent.
Participation held at 4 of 8 tracked indices above their 50-day average, unchanged from the prior session despite the index gain, leaving breadth still at half the tracked set.
One session, from the stored closes of the eleven sector ETFs. Each bar is scaled against the widest move of the day, so the shape is the spread and not an absolute size.
