7.22 Market Update Interpretation: Violent rebound in storage semiconductors, tech main theme fully returns

This week’s clearest profit-making theme in the global market—second to none: AI hardware + storage chips collectively reverse and strengthen.
Many people, after the choppy consolidation and washout in the first two weeks, have already completely turned bearish on the tech sector and even predicted that the semiconductor cycle had ended. But last night’s US stocks slapped everyone in the face with an exceptionally strong move, delivering the strongest one-way rebound in nearly a month.
The core breakout is concentrated in the semiconductor memory sector. The Philadelphia Semiconductor Index surged more than 5% in a single day, fully reversing the short-term weak pattern. Sub-sector targets went on a full-blown celebration: Micron’s market cap returned to the hundred billion-level threshold; SK hynix, Western Digital, SanDisk, and other leading memory giants all jumped 10%+; optical communications and computing/hardware rose in sync; sentiment for the AI hardware track recovered completely.
This rebound is not just a short-term oversold correction—it’s the result of a double resonance between fundamentals and liquidity.
On the fundamentals side, downstream consumer electronics demand is picking up. Leading manufacturers have raised their full-year smartphone shipment targets. Volume growth in lower-end models is driving a rebound in memory chip demand. The industry inventory inflection point is gradually being confirmed, and the pricing disagreement that previously weighed on the sector is steadily being resolved.
On the liquidity side, last night’s US tech funds flowed back sharply. The market ignored fluctuations from the outside and started pricing in the upcoming benefits from the next round of tech earnings season early, lifting risk appetite across the board.
Mapping to the A-share and Hong Kong markets, the logic is completely interchangeable. Yesterday, China’s A-share STAR Market 50 surged more than 10%, and the ChiNext strengthened sharply. Semiconductors, computing power, and optical modules led across the board—this was essentially an early positioning by domestic capital to anticipate a storage memory reversal. With today’s overseas market tailwind, the durability of the tech sector’s rebound is further solidified.
Here is the key trading logic for everyone right now:
1、 Abandon the range-trading mindset: the short-term adjustment in the tech sector has ended, the next leg of the main upswing rebound has begun. Don’t keep fearing at high levels or cut losses at low levels;
2、 Focus on core sub-sectors: prioritize three high-volatility directions—memory chips, AI computing hardware, and optical communications. These are the absolute main lines of this round’s move;
3、 Avoid niche themes: market funds are highly concentrated in the tech sector, and “oddball” themes keep bleeding. Avoid random switching that leads to missing the move.
Markets are always born to reverse in despair, and they keep partying through hesitation.
This round’s rebound in storage and tech has just started—go with the trend and capture opportunities with clear certainty.
