undecided, growth down
rates -0.3sd, growth -0.5sd this week; growth -0.5sd is 0.21sd short of the 0.75sd band, the nearer of the two; 13-week trend: stagflation fear (rates +1.3sd, growth -0.8sd per quarter); 2s10s flattened 23bp over the month

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

The market leaned toward stagflation fear without committing. Driven by crude, this week's core CPI print. Cyclicals underperformed defensives (-0.5sd). The hard data pointed the other way, so the market is trading ahead of the prints.

What rose was long-duration and fee-sensitive, with nothing clearly falling against it. Refiners up while gas producers fell points to crack spreads, not the energy complex.

The most unusual move is Cybersecurity at +3.8sd 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 consumer staples are priced as if it will swing 17% a year while it has actually been swinging 8%, the largest overpayment of the eleven. 3 sub-industries moved broadly with no hand basket over them, the largest Oil & Gas Exploration & Production at -2.4sd, so the hand taxonomy could not see it. What decides next week: whether cyclicals against defensives clears the deadband.

Rotation quadrant

undecided
rates -0.3sd · growth -0.5sd
Neither axis moved enough to name a regime, so there is nothing to call yet. Growth came closer than rates (-0.5sd) and needed to be about 39% bigger to count. Over the last 13 weeks the drift has been towards stagflation fear, which is what to read this week against.

Themes

8 up, 7 down of 82, about 11 by chance
More baskets moved than chance explains: 15 of 82 against about 11 in a quiet week, 8 up and 7 down. 5 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

all known
2 groups found
2 groups of stocks moved together and you already have a basket for every one of them (Natural gas producers, Life science tools), so nothing new was found.

Options market

calm
VIX/VIX3M 0.81 (-0.9sd vs 3y); SKEW 148 (+0.3sd)
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 0.81). Options on consumer staples are priced as if the sector will swing 17% a year while it has actually been swinging 8%, the largest overpayment of the sectors here. Only 3 weeks of this sector data is stored, so the levels are readable but there is nothing to compare them against yet.

Financials1611+5
Materials1915+4
Technology2824+4
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

6 moved and tagged
universe shorts +3.9% on the last print; 13F holders +2.0% last quarter
6 baskets that moved this week carry a positioning tag, but none of them is crowded enough to change how you read the move. How current this is: the short-interest column counts bets placed as of 31 August, about 3 weeks 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

3 uncovered
27 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.

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.
