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. The dollar firmed.

What fell was hard-asset and commodity-linked, with nothing clearly rising against it.

The most unusual move is Building Products at +2.4sd with 100% of members up. Its parent sector has no implied-vol reading, so the options market says nothing about this one either way. Across the sectors, options on communication services are priced as if it will swing 31% a year while it has actually been swinging 14%, the largest overpayment of the eleven. 2 sub-industries moved broadly with no hand basket over them, the largest Building Products at +2.4sd, so the hand taxonomy could not see it.

Rotation quadrant

undecided
rates +2.3sd · 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.

Rates and curve

More rates series moved than chance explains: 9 of 12 against about 5 in a quiet week, all of them up. The biggest was 3m bill (+3.4sd).

Credit, liquidity, risk

8 moved
7 up, 1 down of 23, about 10 by chance
This is an ordinary quiet week in credit and liquidity. 8 of the 23 series moved, and about 10 move in a week when nothing is going on, so nothing here says financial conditions changed.

Themes

15 moved
6 up, 9 down of 82, about 11 by chance
More baskets moved than chance explains: 15 of 82 against about 11 in a quiet week, 6 up and 9 down. 2 of them were carried by a couple of names rather than the whole group, so they are not really themes.

Baskets on one idea, after stripping out market and sector. % = members moving the same way; higher = more believable. ✓ ✗ = its real-world driver moved with or against it. (GICS) = mechanical sub-industry basket, not hand-picked. * = members did not agree beyond chance, so not read as a theme.

Discovery

nothing new
no group cleared the filters
No group of stocks moved together tightly enough to register. The closest was one you already have a basket for, Natural gas producers, which holds together but did not move this week.

tight enough to be a group, but it did not move this week
Stocks that moved together this week, found without the basket list. Thin bar = how tightly; short = probably noise.

Options market

calm
VIX/VIX3M 0.83 (-0.6sd vs 3y); SKEW 145 (-0.1sd)
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 0.83). Options on communication services are priced as if the sector will swing 31% a year while it has actually been swinging 14%, the largest overpayment of the sectors here. Only 4 weeks of this sector data is stored, so the levels are readable but there is nothing to compare them against yet.

Financials19+2.99+10
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

13 moved and tagged
universe shorts +2.1% on the last print; 13F holders +2.0% last quarter
The falls happened in names people had already bet against. 2 of the 9 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 15 September, about 1 week ago. The 13F column is older still, 30 June, about 3 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

2 uncovered
27 sub-industry baskets beside 55 hand baskets
2 sub-industries moved as a group this week and none of your 55 baskets covers them, so you had no way to see them. The largest move on the whole board is one of them: Building Products (+2.4sd).

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.
