2026-06-28 Daily Trend Report

I. Today's Core Conclusions

1. The A-share market overall showed risk appetite contraction today. The Shanghai Composite All-Share Index fell 1.18% to 3,979.7 with turnover of 761 billion yuan; the SME index dropped 1.39% while the Leading Index declined only 0.42%, indicating large-cap blue chips were relatively resilient while small/mid caps faced heavier pressure.
2. The market mainline centered on hard technology and semiconductor supply chains. Lv's Harmonic drove gains with a 20% limit-up, BOE A led the popularity ranking with +4.55%, the memory chip sector exploded (Longke Technology 20cm limit-up), and semiconductor packaging (JCET +3.65%) remained active alongside panel产业链 strength.
3. Geopolitical risks continued to escalate. The Israeli military detected Iranian missiles approaching, Persian Gulf shipping saw sharp vessel reductions due to Middle East conflict, and Fujairah Port emerged as a key crude oil trading hub. Markets broadly expect the Fed to hold rates steady given the complex geopolitical backdrop.
4. HK tech sector valuation repair trend is evident. Global capital is restructuring pricing logic for core Chinese assets, with LT Technology, CATL, and GigaDevice H-shares trading at premiums to their A-share counterparts—breaking the long-standing pattern of 20%-40% A-share premiums over H-shares.
5. The greatest uncertainties stem from the escalation trajectory of Middle East geopolitics and the Fed's policy stance. Further conflict-driven oil price spikes could suppress global risk appetite; unexpected dovish Fed signals could boost growth stock valuations.

II. Market Mainline

Today's market is trading the dual mainline of "hard tech self-reliance + HK valuation repair." On one hand, capital is concentrating in domestic substitution themes: memory chips, semiconductor packaging, and robot harmonic reducers. On the other, the rare H-share premium over A-shares signals global capital's re-pricing of Chinese hard tech assets. If this mainline strengthens, tech sectors should maintain inflows; if it weakens (e.g., heightened external market volatility), earlier strong STAR Market names could face profit-taking.

III. Key Asset Performance

A-share Indices: Shanghai All-Share 3,979.7 (-1.18%), turnover 761B yuan—ample volume but weak index, indicative of structural rotation within a contracting environment. The Leading Index fell only 0.42%, showing blue-chip resilience. The sole counter-trend gainer was the 180 Transport Index (+0.61%), reflecting the safe-haven appeal of shipping amid geopolitical tensions.

Hot Sectors: Memory chips (Longke 20cm limit-up), robotics (Lv's Harmonic 20% limit-up), panels (BOE A +4.55%), semiconductor packaging (JCET +3.65%).

HK Tech: Premiums of LT Technology, CATL, and GigaDevice H-shares over A-shares signal ongoing HK tech valuation repair.

Pharma: Boehringer Ingelheim's weight-loss drug Survodutide showed positive trial results (34% visceral fat reduction, 63% liver fat reduction), providing fresh catalyst for the GLP-1/GCG dual-target pipeline.

IV. Chan Theory Structure Observation

Lv's Harmonic (SH688017) | Daily: 20% limit-up breaking prior resistance, forming a strong daily uptrend. If tomorrow does not see a high-volume long bearish candle pulling back, this is a bullish continuation pattern; if the stock opens low and falls below the limit-up trigger level, the structure fails and short-term adjustment begins.

BOE A (SZ000725) | Daily: +4.55% leading popularity rankings, in an oscillating upward channel. Watch for effective breakout above 6.5 yuan—three consecutive closes above that level would constitute a daily-level third-buy candidate; a pullback below 5.8 yuan support would signal weakness.

Longke Technology (300543) | Daily: 20cm limit-up as the memory sector explodes—short-term sentiment is elevated. Critical to observe whether the limit holds or at least closes green tomorrow; otherwise rapid correction risk looms. The memory sector shows clear rotation characteristics—chasing highs is inadvisable.

Tianshi Technology (SZ002185) | Daily: +10.02% limit-up, ranked #1 on popularity charts (historical data), a core semiconductor packaging name. Sustained volume expansion with price holding above VWAP supports continuation; shrinking volume with stagnation warrants caution.

V. Events and Catalysts

Geopolitical Conflict: Israeli detection of Iranian missiles raises Persian Gulf shipping risks; Fujairah Port is becoming a critical crude oil hub. Further escalation benefits oil/shipping but may pressure global risk appetite.

Fed Policy: Markets broadly expect the Fed to hold rates given geopolitical complexity. Surprise inflation data could force a repricing of rate expectations.

Corporate Events: WWE settled UFC merger litigation with investors, removing a major legal overhang; Boehringer's drug trial results provide fresh GLP-1 catalyst.

Valuation Restructuring: Global capital restructuring Chinese core asset pricing—with H-share premiums on hard tech names signaling the establishment of HK tech valuation repair trend.

VI. Risk Factors

1. Further Middle East escalation could spike oil prices, suppressing global risk appetite and pressuring A-share tech growth valuations.
2. An unexpected hawkish Fed surprise (e.g., dot plot raising rate projections) could strengthen the dollar and trigger EM capital outflows.
3. Memory chips and robotics themes have surged sharply; insufficient capital follow-through could trigger rapid pullbacks.
4. The sustainability of H-share premiums over A-shares is questionable—if this is merely a transient arbitrage opportunity rather than a structural repricing reversal, HK tech valuation repair may disappoint.
5. Market fund flow data is only updated through June 5, lacking the latest institutional money flow reference—caution advised regarding potential divergence between actual capital conditions and price action.

VII. Tomorrow's Observation List

1. Can the Shanghai All-Share stabilize in the 3,950-4,000 range? Watch for turnover contraction below 700B yuan (confirmation of shrinking-volume adjustment).
2. Will Lv's Harmonic hold the limit-up price? Watch for capital divergence in the memory chip sector.
3. Can BOE A effectively break above the 6.5 yuan psychological level?
4. Is the H-A premium persisting? Focus on LT Technology and CATL HK performance.
5. Middle East developments: if tensions ease, oil and shipping sectors could retreat.
6. Fed official speeches and US macro data (employment, inflation).
7. Upon fund flow data updates, observe whether institutional capital rotates from thematic stocks to blue chips.

VIII. Agent Independent Observation

Today's market showed a clear "weak index, structural divergence" pattern. Large-cap blue chips held firm while small/mid caps sold off, yet tech sub-sectors (memory, panels, robotics) were exceptionally active. This divergence suggests capital has not broadly fled but is concentrating bets on high-risk, high-reward tech growth names. Notably, popularity chart data contains lags (some snapshots still from late May)—actual market heat may differ from the rankings.
