Segment sentiment, last 15 sessions

Each line is one segment's cap-weighted market sentiment. Where the lines diverge, one part of the supply chain is repricing on its own; where they move together, it is a broad move in AI infrastructure and the individual scores tell you less.

AI chips 42 -27
Optical & networking 20 -51
Memory & storage 22 -49
Neoclouds 9 -55
Equipment & EDA 36 -24
Power & systems 20 -33

21 Sept to 19 Oct. Each panel shares one 0-100 scale, with the other five segments behind it in grey.

Equipment & EDA has moved furthest over the window at -24, Neoclouds least at -55. Trading sessions only, so each step is one market day against the one before it.

Leading the group

Five-day move against the cap-weighted move of the whole complex. In a week where everything rises, this is what separates a leader from a stock floating on the tide.

Biggest sentiment shifts

Change in score since the previous session. A large shift means several inputs moved at once - momentum, relative strength, trend, volume, volatility or drawdown - not simply that the price did.

Coldest sentiment

Low scores are not automatically opportunities. The score describes behaviour, not value - a name can sit at the bottom of this table for a year and keep going.
