The full day: index block, sentiment, every mover and the open questions
7,623.68▼ -0.52%1d
Capitalisation weighted, so a move in the largest companies moves it more than a move in the smallest.
the last 40 stored closes, scaled to their own range
25,955.34▼ -0.21%1d
Every Nasdaq listing, weighted by capitalisation and heavy in technology.
52,215.16▼ -1.23%1d
Thirty names weighted by price rather than by capitalisation, so it can disagree with the S&P for arithmetic reasons alone.
2,775.90▼ -0.29%1d
Small capitalisation names. Read against the S&P, it is the size half of how broad a day was.
216.54▼ -0.77%1d
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.
Cap weight against equal weight+0.25pp
The cap-weighted index outran the equal-weighted one, so the largest companies carried more of the session than their number.
Sentiment
Sentiment composite
28▼ -12.94%1d
This system's own composite of up to seven stored inputs, 0 (extreme fear) to 100 (extreme greed), computed after each close; not CNN's index (work item #699). Context for whether sentiment confirms the tape or contradicts it.
19.45▲ +2.21%1d
Expected thirty day volatility from S&P 500 options. Rising with the index is the contradiction worth seeing.
