The bounce in the deeply oversold commodity names kept going — DOW and LYB both continued climbing this week, and LYB crossed back above RSI 50 for the first time in this cluster's recent scans. But the specialty complex isn't holding steady in exchange: LIN posted the sector's biggest weekly decline (-3.13%), and its trend classification slipped from strong-up to weak-down, ending its run as the group's "steadiest hold." APD and ECL also cooled further, while PPG and DD both stabilized modestly. This is a rotation continuing, not resolving.

DOW AND LYB — BOUNCE EXTENDS, LYB CROSSES RSI 50: DOW ($29.92, RSI 46.8, was 39.1) and LYB ($59.17, RSI 52.2, was 39.4) both continued climbing this week — DOW up 3.07% and LYB up 5.0% on 7D. LYB is the standout: its RSI crossed above 50 for the first time in this cluster's recent scans, and its distance from the 52-week high narrowed to -29.51% (was -32.87%). DOW's distance from high also improved slightly (-32.08%→-30.0%). Both remain in pullback regime rather than a confirmed uptrend, but this is now three scans running of stabilization off the deep-oversold lows.

LIN LOSES "STEADIEST HOLD" STATUS: LIN ($513.22, RSI 45.5, was 55.6) posted the sector's worst weekly decline this scan (-3.13% 7D) and its trend classification downgraded from strong-up to weak-down — a reversal from last scan's framing of LIN as the sector's cleanest large-cap structure. Its 30-day change compressed to roughly flat (+0.21%, was +2.78%) and distance from 52wk high widened to -6.38% (was -3.36%).

SPECIALTY COMPLEX (APD, SHW, ECL) STILL COOLING, NOT BROKEN: APD ($295.62, RSI 52.8, was 57.3), SHW ($331.32, RSI 50.7, was 53.9), and ECL ($272.83, RSI 50.9, was 53.1) all continued easing off the regime-flip breakout flagged in early July, but none broke trend structure. APD remains up 6.15% over 30 days despite the cooldown. SHW and ECL both still carry unresolved death crosses.

PPG AND DD — STABILIZED, NOT RESOLVED: PPG ($117.36, RSI 50.0, was 48.2) recovered from last scan's sharp -5.05% weekly drop, posting a small positive week (+0.51%) and holding its strong-up trend. DD ($135.29, RSI 43.4, was 39.2) also stabilized on the week (+0.45% 7D) after last scan's rollover, though its 30-day change deepened further negative (-4.16%→-5.48%).

• DOW and LYB extended their bounce: RSI 39.1→46.8 and 39.4→52.2, both up 3-5% on the week. LYB crossed above RSI 50 for the first time in this cluster's recent scans.
• LIN reversed from last scan's "steadiest hold" call — posted the sector's worst 7D decline (-3.13%) and its trend downgraded from strong-up to weak-down.
• APD, SHW, and ECL all continued cooling from the early-July breakout levels, but none broke trend structure; all remain up or roughly flat on 30D.
• PPG stabilized after last scan's sharp -5.05% weekly drop, posting a small positive week and reclaiming RSI 50.
• DD's weekly decline reversed to a small positive print (+0.45%, was -4.38%), though its 30-day change deepened further negative.

• Is LYB's cross above RSI 50 the start of a confirmed bottom, or another wobble inside a longer downtrend?
• Is LIN's reversal a one-week pullback inside an otherwise intact structure, or the start of the specialty complex rolling over the way DOW/LYB did earlier in the year?
