Market phase shifts from retreat to early recovery
China's A-share market is entering a China A-share market recovery phase as sentiment indicators stabilize after a multi-day retreat. The seal rate on daily limit-up stocks rebounded to 84% on September 7 from a low of 44% four days earlier, while the ChiNext index climbed 2.63% and trading volume held near 1.95 trillion yuan. The improvement is meaningful but not yet confirmed — analysts caution that two consecutive sessions above 2 trillion yuan in turnover and a seal rate sustained above 75% would be needed before declaring the recovery durable.
The liquid cooling mainline has earned the highest capital recognition as industrial logic, earnings delivery and short-term momentum align around AI compute hardware upstream. Jitai shares, a liquid cooling leader, posted five limit-up days in six sessions, the strongest consecutive-board performance in the current cycle. The sector's appeal rests on hard industrial demand from data center buildout, visible earnings contributions and broad short-term fund participation — a combination that has held up even during the broader market's retreat.
Defense stocks form a parallel mainline
Defense military stocks have advanced as a second parallel mainline, supported by a 32.92% year-over-year increase in first-half net profit among CSI Military Industry Index companies. The sector showed inverted leadership during the September 2 market drop, rising when the broader index fell — a pattern that typically signals institutional positioning ahead of catalysts. Military trade and aviation equipment sub-sectors are both attracting capital, though the direction carries lower short-term trading value than liquid cooling due to less concentrated momentum.
AI applications, including short drama, entertainment and media names, remain a tertiary rotation candidate with an estimated 65% probability of activation over the next three trading days. These names benefit from high-low-cut rotation when the primary mainlines pause, but sustainability has yet to be confirmed.
Oil supply risk caps the upside
The Hormuz Strait oil supply disruption has become a structural factor in global asset pricing, with the U.S. Energy Information Administration estimating roughly 600,000 barrels per day of supply still disrupted. The disruption is expected to persist through the end of 2027. Brent crude has climbed above $94 per barrel, and Goldman Sachs has warned that prices could reach $120 if the situation escalates further. WTI is trading near $91 per barrel.
The oil risk introduces an asymmetric downside for A-share traders. A breach of $100 per barrel would likely trigger a rotation out of growth and technology names into energy and defensive sectors, undermining the current liquid cooling trade. The 10-year Treasury yield has already risen to 4.75%, and the Federal Reserve's September rate hike probability has climbed to 50-65%, tightening the external liquidity backdrop.
Position strategy and key signals
The recommended approach is controlled-position observation with selective offensive positioning, targeting 50-60% total allocation split between offensive liquid cooling and defense holdings and defensive consumer, energy and agriculture exposure. Small positions in confirmed mainlines are appropriate at this stage, but heavy chasing is not.
The upgrade trigger is two consecutive sessions with trading volume above 2 trillion yuan and a seal rate above 75%, which would justify increasing allocation to 70%. The downgrade trigger is either a Brent crude breach of $100 per barrel or a break in the consecutive-board streak of liquid cooling leader Jitai shares — either event would signal that the recovery thesis has failed and a return to defensive positioning below 30% is warranted.
The People's Bank of China conducted a 500 billion yuan three-month outright reverse repo operation on September 7, providing a modest liquidity cushion. Whether that support is sufficient to sustain the recovery through the oil-driven uncertainty will be the defining question for the next several sessions.
