# Focus on trading volume and the relative strength of different sectors!

$Shanghai Composite Index sh000001$ Yesterday was like a long-awaited rain after a drought, although it was just a light drizzle, it was enough to make everyone happy for a day, finally recovering some blood.

That fatal blow on Tuesday almost completely broke the psychological defense line of many people. So from after the market closed until yesterday morning, I kept encouraging everyone repeatedly, afraid that people would fall before dawn.

Yesterday afternoon, the tech sector led a strong V-shaped recovery, with stocks generally rising, which finally gave an explanation to friends who held on until the end.

The repair and recovery are worth celebrating, but there is still a long way to go for a real reversal.

Today, focus on two key points, both are indispensable, directly determining whether it's a counterattack or defense later:

1\. Trading Volume  
Yesterday, the index rebounded with over 3,500 stocks rising, but the trading volume actually shrank by 160 billion, indicating that incremental funds have not entered at all, and it's still quantitative trading entertaining itself.  
It's understandable that there's no volume on the first day of a rebound, but if there's no increase in volume today, sentiment will definitely weaken.

2\. Sector Strength Comparison  
Yesterday's rebound was led by Hong Kong stocks moving first, with tech taking the lead. This is a good signal.  
This morning, focus on whether the war sector (energy), which was hit yesterday, is picking up.  
This is a reverse indicator—  
If tech continues to suppress energy, sentiment will gradually warm up;  
otherwise, be careful.

For now, don't pay too much attention to the index; it hasn't left the danger zone yet, and the future relies entirely on sentiment.

Now let's look at the thematic directions:

1\. Computing Power (Yesterday's Rebound Pioneer)

Yesterday, computing power alone sounded the horn for the counterattack.  
During the trading session, there was direct positive news:  
Alibaba Cloud raised prices, AI computing power cards increased by 5%–34%, intelligent computing storage increased by 30%, and scarce computing power began to shift towards Token business.

After the market closed, Baidu also followed suit:  
Starting April 18th, AI computing power prices will increase by 5%–30%, and storage by about 30%.

In fact, as early as January, overseas cloud providers had already raised prices:  
AWS increased by 15%, Google Cloud by up to 100%.

The collective price increase by global cloud providers sends a very clear signal:  
AI computing power has changed from an optional resource to a scarce strategic asset.

Last time, computing power was about to break out but was suppressed by risk warnings.  
This time, the logic is fully connected from upstream to downstream, so it must be viewed with higher regard.

2\. Storage Chips (Strongest Performance, Plus Major Catalysts)

The only main line that has emerged in semiconductors.  
I've always had confidence before, and the core reason is performance—Bewei Storage is the strongest backing of the sector.

Yesterday, it was led by the 300 elasticity targets. Old fans know that every time the sector strengthens, it's basically these few, tried and true.

After the market closed, another heavy news broke:  
The largest union of Samsung in South Korea passed a strike vote, with 93.1% in favor.  
Starting May 2nd, there will be an 18-day strike, affecting half of the production capacity at the Pyeongtaek plant, which is the core production capacity for global DRAM and HBM.

Performance as a foundation + surging demand + Samsung strike reducing production  
Storage still has room to grow.

But remember its "scumbag attribute":  
Acceleration is a selling point, divergence is the buying point.
