Segment sentiment, last 20 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.
30 Jul to 28 Aug. Each panel shares one 0-100 scale, with the other five segments behind it in grey.
Memory & storage has moved furthest over the window at -8, Neoclouds least at -26. 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.
Lagging the group
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.
Hottest sentiment
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.
