driver contradicts
Look at = up this week, members agreeing beyond chance, and 2 weeks running or a move over 2.0sd. Move out of = same rules, downward. Mechanical ranking of residual moves, checked by the backtest, not a forecast. Tags: driver = the basket's real-world series moved with it (confirms) or against it; shorts and institutions from FINRA and 13F, against the universe; vol = parent sector implied vol on the week. Backtest 2023-04-07 to 2026-09-04, look-at minus move-out-of vs sector: 1 week +0.52% (t 1.83, 166 wks), 4 weeks +0.64% (t 0.85). Positive but not significant at 4 weeks: a screen with a weak one-week edge, not a signal. sd = size of the move vs a normal week for that series; under 0.75 is no move, 2 is big.

The view

Inflation pricing moved up with no matching growth signal, so the regime is unresolved. Driven by this week's core CPI print. Yields rose without breakevens, which is a real-rate move. CCC spreads widened a little (+0.9sd) with high yield flat; one week, not yet a warning. The dollar weakened.

What rose was AI capex, with nothing clearly falling against it. Datacentre baskets rising while software fell says AI capex is intact and the software sell-off is about rates and the application layer, not tech.

The most unusual move is Vertical SaaS at -3.1sd with 100% of members down. Its driver moved the same way (10y Treasury +2.1sd), so this reads as the real-world series repricing, not a rotation. Shorts were covering into the fall, which reads as capitulation rather than a fresh leg. Its parent sector has no implied-vol reading, so the options market says nothing about this one either way. Across the sectors, options on financials are priced as if it will swing 16% a year while it has actually been swinging 9%, the largest overpayment of the eleven. 3 sub-industries moved broadly with no hand basket over them, the largest Health Care Equipment at -2.2sd, and 2 of them are technology, so there is no technology basket at all. One unnamed cluster of 9 names moved together (-1.3sd, cohesion 0.35). Look at the ticker list before believing it; low cohesion clusters are usually noise. What decides next week: whether CCC widening spreads into broad high yield.

Rotation quadrant

undecided
rates +2.1sd · growth +0.1sd
Neither axis moved enough to name a regime, so there is nothing to call yet. Growth came closer than rates (+0.1sd) and is nowhere near the bar. The last 13 weeks have no direction either, so this is not a pause in the middle of a bigger move.

More credit and liquidity series moved than chance explains: 12 of 23 against about 10 in a quiet week, 9 up and 3 down. The biggest was Oil vol (OVX) (+2.5sd).

Themes

12 moved
5 up, 7 down of 81, about 11 by chance
More baskets moved than chance explains: 12 of 81 against about 11 in a quiet week, 5 up and 7 down. One of them was carried by a couple of names rather than the whole group, so it is not really a theme.

Discovery

1 unnamed
4 groups found
9 stocks moved together with no basket covering them (-1.3sd), but they only move together loosely, so it is probably coincidence (cohesion 0.35).

Options market

calm
VIX/VIX3M 0.85 (-0.3sd vs 3y); SKEW 154 (+1.1sd)
One month of protection on the S&P is unusually cheap against three months, which is the shape of a market expecting nothing soon (ratio 0.85). Options on financials are priced as if the sector will swing 16% a year while it has actually been swinging 9%, the largest overpayment of the sectors here. Only 2 weeks of this sector data is stored, so the levels are readable but there is nothing to compare them against yet.

Front VIX over 3-month VIX: above 1 = stress is now. SKEW high = the tail is already hedged. Per sector: implied vol a month out, its change this week, realised vol last month, and the gap. Biggest gap = where options are most worried relative to what price did.

Positioning by basket

7 moved and tagged
universe shorts +3.9% on the last print; 13F holders +1.3% last quarter
The falls happened in names people had already bet against. 2 of the 4 baskets that fell were among the most shorted in the index before this week even started, so there is less fuel left in the move. How current this is: the short-interest column counts bets placed as of 31 August, about 2 weeks ago. The 13F column is older still, 31 March, about 5 months ago, so “institutions added last quarter” means more funds held these names at that date. It says nothing about what anyone did during this move.

Per basket, median of members. DTC z = days-to-cover against each name's own 3 years (over +1.5 = crowded short). Shorts = change in short shares on the last FINRA print minus the universe. 13F = change in institutional holder count last quarter minus the universe. Slower prints than price; context, not triggers.

Blind spots

3 uncovered
26 sub-industry baskets beside 55 hand baskets
3 sub-industries moved as a group this week and none of your 55 baskets covers them, so you had no way to see them. 2 of them are technology (Communications Equipment and Semiconductors), which means you have no technology basket at all.

Every S&P 500 name grouped by its GICS sub-industry, scored like a hand basket. Listed: sub-industries that moved broadly this week with no hand basket covering them, so the taxonomy missed them. Disagree = a hand basket and its sub-industry cousin moved opposite ways.
