Key takeaways
1
The S&P 500 fell 4.36% while the equal weight fund fell 2.89%, a gap of -1.46 points. The average constituent held up better than the index, so the weakness was concentrated in larger names.
2
Only 2 of 8 tracked indices sit above their 50-day average, down from 4 last time, while the VIX rose 67.25% to 27.78. Breadth and the volatility reading both point to a broad risk-off session.
3
Technology fell 8.00% against 0.59% for Communication Services, a gap of 7.41 points. Industrials and Consumer Discretionary also fell more than the market, so the weakness was not even across sectors.
4
Lumentum, Micron, AMD, Marvell and Dell each fell further than XLK, by 6.89 to 10.68 points. Their coded cause is the same Technology move, so the chip selloff was larger than the sector fund itself.
The full day: index block, sentiment, every mover and the open questions
7,353.73▼ -4.36%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
24,315.00▼ -5.52%1d
Every Nasdaq listing, weighted by capitalisation and heavy in technology.
51,523.06▼ -3.44%1d
Thirty names weighted by price rather than by capitalisation, so it can disagree with the S&P for arithmetic reasons alone.
2,729.89▼ -4.45%1d
Small capitalisation names. Read against the S&P, it is the size half of how broad a day was.
216.87▼ -2.89%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-1.46pp
The equal-weighted index outran the cap-weighted one, so the session was broader than the headline index makes it look.
Sentiment
Sentiment composite
23▼ -39.22%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.
28.18▲ +69.66%1d
Expected thirty day volatility from S&P 500 options. Rising with the index is the contradiction worth seeing.
