EXECUTIVE SUMMARY

Friday’s modest positive-breadth structure reversed on 9/28 into moderate risk-off conditions. Negative directional observations totaled 337 versus 263 positive, a 1.28× negative skew, while extreme upside and downside were balanced at 113 each. Healthcare expanded into the dominant downside cluster and Energy weakened through GLND’s sharp reversal. EGG and LFCR supplied exceptional upside, while CANG, MX, and a recovering WYY kept Financials, Technology, and Industrials from becoming uniformly weak. Continuity remained strong but unstable as SDEV and SHMD faded, XNDU and DAVA returned to downside, and MNTK’s recovery failed.

HOURLY MARKET TIMELINE

9:38–10:53 a.m. ET — The session opened with a slight positive tilt: 55 positive directional records versus 51 negative, and 25 extreme gains versus 11 extreme losses. LFCR held near +56%, EGG entered at +34.6%, while MNOV and ACET established significant Healthcare downside. CANG and MX provided persistent positive breadth.

11:08–11:53 a.m. ET — Breadth turned negative at 55 losses versus 42 gains. EGG accelerated to +71.8% and LFCR remained near +56%, but MNOV weakened below -32% and ACET remained near -25%. The tape became increasingly polarized.

12:08–12:53 p.m. ET — Negative breadth held at 49 versus 38 positive observations. EGG and LFCR remained extreme upside leaders, while MNOV reached -34.0%, ACET stayed near -23%, and GLND fell as low as -22.1%, confirming the Energy reversal.

1:08–1:53 p.m. ET — Weakness broadened to 59 negative versus 45 positive records, with extreme losses rising to 23 versus 16 extreme gains. LFCR and EGG stayed elevated, but ACET, MNOV, APYX, and GLND sustained significant downside.

2:08–2:53 p.m. ET — Negative breadth remained dominant at 60 versus 46. EGG and LFCR continued as isolated upside anchors, while ACET, MNOV, and GLND remained deeply negative. CANG held persistent double-digit strength.

3:08–3:53 p.m. ET — The session closed at its weakest breadth: 63 negative versus 37 positive records and 25 extreme losses versus 18 extreme gains. LFCR remained stable near +56% and EGG above +43%, while ITG appeared near -30%, ACET closed near -28%, and MNOV remained below -20%.

FILTRATION SUMMARY

The session contained 858 qualifying market-hours records across 26 snapshots and 70 unique tickers. Financial remained largest at 27.2%. Technology represented 19.3%, Healthcare 19.2%, and Industrials 11.4%. Healthcare generated 90 losses of at least 3% and 69 extreme losses; Energy added 40 losses and 21 extreme losses. Financials, Technology, and Industrials supplied meaningful positive breadth, but not enough to offset widespread weakness.

Movement distribution: 113 surges of at least 10%, 150 gains of 3%–10%, 258 flat observations within ±3%, 224 losses of 3%–10%, and 113 selloffs of at least 10%. Principal anomaly flags included EGG, LFCR, MNOV, ACET, GLND, CANG, MX, SDEV, SHMD, XNDU, APYX, IMDX, SMJF, ITG, and SCYX. ACET recorded the largest persistent negative drift at -19.9%; EGG led positive drift at +11.9%.

CONTINUITY RELEVANCE

Overall relevance: YES. All five tests passed. GLND, SDEV, SHMD, XNDU, WYY, DAVA, MNTK, GLOO, and TRT preserved recognizable Friday signals. Direction changed materially: GLND and SDEV reversed lower, WYY recovered, MNTK’s recovery failed, and Healthcare and Energy became coherent downside clusters.

PRIOR-SESSION COMPARISON

The market reverted from Friday’s modest positive bias to moderate risk-off. Negative breadth rose to 337 versus 263 positive observations. Healthcare share increased 6.2 percentage points and generated 69 extreme losses; Energy share rose 3.3 points with 21 extreme losses. Technology’s extreme downside normalized while its positive tail expanded, and Industrials retained exceptional upside through EGG despite lower participation. GLND reversed from +6.7% to -12.6% intraday, SDEV fell 9.3%, and WYY recovered 11.2%.

NARRATIVE SIGNAL

Healthcare and Energy drove the return to risk-off conditions, while EGG and LFCR formed exceptional positive countertrends. CANG, MX, and WYY supported positive participation elsewhere, preventing a uniformly negative tape. Persistent names remained highly unstable, with several Friday leaders reversing direction or losing momentum.

DAILY LIGHTHOUSE SNAPSHOT

Daily thesis: the market reverted to moderate risk-off. Healthcare produced 69 extreme losses, GLND reversed to a -12.6% intraday decline, and SDEV fell 9.3%. EGG gained 11.9% intraday and LFCR held above +54%, while WYY recovered 11.2% from Friday’s extreme decline.

Next-session tests:

• Whether EGG and LFCR retain persistent extreme upside.

• Whether ACET and MNOV sustain Healthcare downside leadership.

• Whether GLND and SDEV stabilize after sharp reversals.

• Whether WYY extends its recovery.

• Whether CANG and MX confirm positive breadth.

CONTINUITY LOG

The complete September 28 entry was appended to the cumulative Lighthouse Continuity Log. It records the structured filtration summary, continuity relevance, comparison with 9/25, narrative signal, tracker actions, active state, next-session tests, and scope methodology.

BOTTOM LINE

September 28 confirmed continuity relevance but marked a return to moderate risk-off conditions. Healthcare and Energy weakness outweighed improving participation elsewhere, while EGG and LFCR created exceptional but concentrated upside. The next session should be judged on whether those two leaders persist and whether ACET, MNOV, GLND, and SDEV stabilize or deepen the downside regime.

METHODOLOGY AND SCOPE

Analysis includes every LighthouseHistoryLog observation dated September 28, 2026 within regular U.S. market hours. Friday September 25 was used as the latest prior valid U.S. market session; weekend records were excluded from continuity judgments. Source “Change” is measured versus prior close. Session drift compares the first and last observed market-hours price for each ticker. Persistence is appearances divided by 26 snapshots. No sampling was used.
