$SSE Index(000001.SH)$Shanghai Composite Index sh000001$ There are too many uncertainties in the market right now, with panic sentiment spreading, making trading in March significantly more difficult.

The expected main upward wave has been delayed, while unwarranted divergences occur every day.

Everyone knows deep down: the logic of computing power is solid, domestic substitution is on track, and the long-term outlook for big tech is fine.

But once indiscriminate quantitative selling hits, a sharp drop emerges, and the urge to cut losses is still hard to resist.

What should be done in this kind of market?

Remember one thing: there is no systemic risk at present, only emotional panic.

This can be seen from the index: every time it pulls back to a key level, there is active buying support, especially near the 60-day moving average. No matter how scary the external environment is or how poorly US stocks perform, as long as it touches this level, a strong rebound can usually be pulled off.

Market sentiment is now near a freezing point. If there is another inertial drop tomorrow and the index pulls back near the 60-day moving average, it remains an excellent node where opportunity outweighs risk.

 Now let's look at the sectors:

1. Commercial Aerospace

Next week is packed with catalysts:

- Dreami is expected to launch its first space computing power satellite.

- March 17–18: The 2nd Commercial Aerospace Conference will be held in Shenzhen.

The sector has been adjusting for 3 consecutive days, with selling pressure released, now at the lower edge of the trading range + double support from the 60-day moving average.

With strong event-driven catalysts next week, if it stabilizes with increased volume and turns upward, it will be a signal of an oversold rebound, suitable for short-term speculation.

2. Brain-Computer Interface

There has been a major breakthrough: China's first invasive brain-computer interface medical device has been approved for market, moving from the lab to a real clinical product.

Coupled with continuous catalysts from international forums, capital has started to pay attention.

The sector is at a low position. If volume increases subsequently, the willingness to go long will be further enhanced, suitable for low-position accumulation.

3. Electric Power

Many are asking: Is the power sector rally over?

My conclusion: There is no signal of it ending yet.

As long as it recovers and closes in the green tomorrow, or even forms a bullish engulfing pattern, its main theme status remains, and the upward trend is unchanged. No sector, no matter how strong, can rise without adjustments.

In short, control your position, don't panic, and don't cut losses.
