The board split cleanly down the middle this week: the EV-maker complex broadly recovered (TSLA RSI 48.7→58.0, RIVN +10.34% on the week, LI/NIO/XPEV all clearing back out of oversold) while the clean-energy-adjacent industrial names cratered — NXT posted the board's worst weekly move (-14.99%, RSI 47.3→34.3, newly oversold) and TE deepened its decline for a second straight scan (30-day change -23.27%→-26.7%). SEDG remains the board's most damaged long-term structure, sitting -27.2% below its 200-day with a near-flat trailing year. SQM crossed into overbought (RSI 58.7→72.8) on a strong week, and the oversold cohort widened from three names to six.

Data as-of 2026-08-21 close. All numbers from precomputed summaries/ev-clean-energy.json. Prior scan: 2026-08-14-ev-clean-energy (2026-08-14, data as-of 2026-08-14 close) — the summary's own 7-day window runs 2026-08-14 to 2026-08-21, so the comparisons below line up exactly with that prior scan.

TSLA continued clearing out of its earlier weakness: RSI climbed from 48.7 to 58.0, price from $342.27 to $362.86, and the week alone added +6.02%. TSLA still sits 10% below its 200-day average ($403.32) despite a positive trailing year (+13.35%) — the engine's own thesis flag still reads "intact," but on the technical test alone this is a trend currently under test at the 200-day, not comfortably above it. The Chinese and US EV-maker complex broadly firmed alongside it: LI's RSI rose from 40.2 to 54.7 (30-day change flipping to +7.67% from -3.69%), NIO cleared oversold (RSI 39.2→46.7), XPEV cleared oversold too (RSI 36.4→46.8), and RIVN posted the board's strongest week (+10.34%, RSI 43.5→56.8, just ahead of SQM's +10.18%). All four of LI, NIO, XPEV, and BYDDY remain below their 200-day averages with negative trailing-year returns (LI -44.37%, NIO -16.43%, XPEV -46.42%, BYDDY -17.74%) — this week's bounce is a recovery inside still-damaged longer trends, not a new uptrend.

NXT had the board's worst week by a wide margin: RSI fell from 47.3 to 34.3, price from $101.47 to $86.18, a -14.99% weekly drop that pushed it straight into the oversold band. Despite carrying real multi-year strength (change2y +115.02%, change3y +135.27%), NXT is now 21.1% below its 200-day average — a trend genuinely under test after this week's break, not simply a pullback. TE deteriorated for a second straight scan: RSI eased from 44.5 to 38.0, the week down -13.31%, and the 30-day change worsened again to -26.7% from -23.27%. TE's longer-horizon numbers are enormous (change1y +198.65%, change2y +242.64%) but it's now 31.7% below its 200-day — the same "under test despite a huge multi-year run" pattern as NXT, just more extreme.

SEDG remains the board's most structurally damaged name: RSI ticked up slightly (34.8→35.9) but the 30-day change is still -35.61%, and it sits 27.2% below its 200-day with a trailing year that's essentially flat (+2.05%) — genuinely weak on every window, not a pullback story. BE weakened further (RSI 51.1→42.6, 30-day change -3.94%→-7.68%) despite an enormous multi-year record (change1y +349.36%, change2y +1639.64%) and still sitting 8% above its 200-day — that combination reads as a deep pullback inside an intact trend, distinct from SEDG, NXT, and TE.

On the other side of the board, ALB extended (RSI 62.2→67.8, 30-day change +9.15%→+21.97%) and SQM crossed into overbought (RSI 58.7→72.8, week +10.18%) — both up more than 80% over the trailing year, though ALB still sits 7.6% below its 200-day while SQM is comfortably above (+9.7%). LIT and ENS both held up well, remaining above their 200-day averages with strong trailing-year gains.

• NXT cratered: RSI 47.3→34.3, price $101.47→$86.18, 7D -1.73%→-14.99%, 30D -7.02%→-17.89%.
• TE weakened further: RSI 44.5→38.0, price $5.11→$4.42, 7D -12.65%→-13.31%, 30D -23.27%→-26.7%.
• SEDG held near its lows: RSI 34.8→35.9, price $32.42→$30.83, 30D -40.6%→-35.61% (slight improvement, still the group's worst).
• BE weakened: RSI 51.1→42.6, price $229.94→$201.45, 7D +4.83%→-12.44%, 30D -3.94%→-7.68%.
• SQM crossed into overbought: RSI 58.7→72.8, price $74.32→$81.96, 7D +3.29%→+10.18%, 30D +3.91%→+18.42%.
• ALB extended: RSI 62.2→67.8, price $136.15→$143.25, 30D +9.15%→+21.97%.
• TSLA climbed out of its earlier weakness: RSI 48.7→58.0, price $342.27→$362.86, 7D +4.17%→+6.02%, 30D -13.23%→-2.98%.
• RIVN posted the group's strongest week: RSI 43.5→56.8, price $15.36→$16.97, 7D -4.00%→+10.34%, 30D -13.71%→-1.22%.
• LI cleared toward neutral: RSI 40.2→54.7, 30D -3.69%→+7.67%.
• NIO cleared oversold: RSI 39.2→46.7, 30D -10.14%→-0.86%.
• XPEV cleared oversold: RSI 36.4→46.8, 30D -15.09%→-5.14%.
• LCID worsened, newly oversold: RSI 44.6→38.2, 30D +4.54%→-18.73%.
• FSLR held roughly flat: RSI 49.0→42.9, 30D +0.78%→+2.6%.
• Oversold cohort widened from 3 to 6: SEDG, NIO, XPEV (prior) → LCID, SEDG, TAN, ICLN, TE, NXT (now) — NIO and XPEV cleared while five names newly entered or remained.

Golden-cross names (RIVN, BE, ENPH, SEDG, FSLR, LIT, DRIV, TAN, ICLN, NXT, ENS, TE) mean the 50-day average sits above the 200-day — but the cross label is misleading on its own this scan: NXT and TE both carry golden crosses yet are now well below their 200-day averages after this week's break, while SEDG's continued deterioration happens inside a technically golden-crossed structure too. Death-cross names (TSLA, BYDDY, LI, NIO, XPEV, LCID, PLUG, ALB, SQM, KARS) include several genuinely weak long-term structures (LI, NIO, XPEV, all below their 200-day with deeply negative trailing-year returns) alongside names that are actually fine on the long horizon despite the death-cross label (SQM +81.13% 1-year, 9.7% above its 200-day; ALB +81.47% 1-year though still 7.6% below its 200-day). The single most reliable split this scan is 200-day distance plus trailing-year return, not the cross label: RIVN, BE, SQM, LIT, ENS, and DRIV sit above their 200-day with positive multi-year records (deep-pullback framing where applicable); TSLA, SEDG, NXT, TE, FSLR, ENPH, PLUG, LI, NIO, XPEV, BYDDY, LCID, ALB, KARS, TAN, and ICLN sit below theirs, with the trend genuinely under test even where the multi-year record is strong.

Capitulation (RSI<25): None.

Oversold (25-40): NXT (34.3), SEDG (35.9), TE (38.0), LCID (38.2), TAN (39.0), ICLN (39.4) — six names, up from three (SEDG, NIO, XPEV) last scan, with NIO and XPEV both clearing out this scan.

Neutral/Strong (40+): The rest of the board, spanning BE (42.6) to ALB (67.8).

Overbought: SQM (72.8) — the board's only extended print.
