Computing collapse? Is the lobster already dead? Afternoon rotation in aerospace! Short-term trading self-analysis

【Personal Profile: In my forties and not confused about life, I have failed twice in entrepreneurial ventures. After many twists and turns, I rekindled my old dream in April 2025, entering the market with a capital of 50,000 to trade stocks and support my family. My goal is to achieve a stable monthly profit of 15,000 and withdraw the profits.】 [Taogu Ba]

【Trading Mode Overview: Right-side ultra-short trader, capital flow style, mainly focusing on core leading stocks in popular market sectors, fast operation rhythm, short holding periods! Skilled in turning divergences into consensus and mid-trades, avoiding left-side low buys during pullbacks, firmly avoiding leveraged stocks, and generally not engaging in futures or Hong Kong mapped stocks.】**

Today’s Market Sentiment Intensity: 64 degrees

Number of stocks falling: 790

Market volume shrank: 249.7 billion
Number of limit-up stocks: 55
Limit-up rate: 72%
Number of limit-down stocks: 4**

Note: The number of limit-ups has increased, and the market is generally rising, but I feel that short-term trading has become more difficult today.

Look at the chart below: Do you notice any characteristics? Yes, it’s the pattern of making money one day and losing the next, just like market hype—no sustainability. This vividly shows that since the beginning of this month, hype-driven trading has lacked consistent profitability.

In summary, the market isn’t as good as imagined, nor as bad. Since the start of the year, I’ve been hovering between small gains and small losses this month. Objectively, market sentiment is low, causing most short-term traders to stagnate so far. But upon reflection, I’ll list some disadvantages of short-term trading and share them—see if you make the same mistakes:

(1) Greed! Expectations too high! Currently, the market is in rotation, and increased risks from external conflicts make many short-term funds avoid uncertainty. So, you can see that the few hot spots are mainly based on overnight arbitrage using quantitative methods. Quantitative trading requires high volatility for high buy-sell swings but doesn’t pursue the continuity of themes. So, many of my trades this month started well, but the next day, under my subjective optimism, I recklessly increased positions (possibly influenced by some capital inflow signals during bidding or intraday), and I didn’t take profits timely at the peak, turning big gains into small ones, and small ones into tiny legs, or even small losses. In quantitative-driven hype, you can only think arbitrage, not main upward moves—profit should be taken promptly.
(2) High-frequency trading is not advisable! Since the new year, I’ve been trading daily, and although my positions are controlled, the high frequency inevitably increases mistakes, causing me to hover between small gains and small losses. Not being fully out of the market to observe makes it harder to adjust and find the right rhythm—this is an area I need to improve, learn from top traders!
(3) Rigid trading habits become targets for quantitative harvesting. As a consistent right-side trader, chasing strength has become natural, but chasing strength often makes me a target for quantitative harvesting, especially in the morning when chasing strength. Facing the day’s uncertainty risk is very high, so before emotions fully recover, it’s better to focus on low buys—ineffective trades are just a waste of time and capital.
(4) Lack of objective subjective follow-up. Similar to today’s large-scale operation buying Meiliyun expecting to position for Shun Na. My capital layout probably pre-judged my short-term predictions, which is subjective market perception. Shun Na, as the top board of the electro-computation collaboration, is a market choice, and Meiliyun is a mid-level stock. I reviewed and analyzed objectively yesterday, but today I fell into a dilemma, participating in some lucky add-ons. Every failure is caused by overconfidence and outside-the-pattern operations.

Hope these points give fellow short-term traders some reflection!

Review of today’s core popular stocks based on my operations:

(1) Stop-loss on Tuowei Information. From profit to small loss, exited. Today’s opening was below expectations, and it couldn’t quickly rise, so I had to exit. Entered last Friday’s late session, sold prematurely yesterday after a quick rise, then re-entered on the board, and exited small loss today. This rhythm shows how difficult sustained short-term trading is!

(2) Big gains turned into big losses, Meiliyun got caught. The morning opening was a weak-to-strong shift, with a quick addition at the open, feeling very insightful at the time, with a 700 million order far exceeding Shun Na’s, showing intent to position. But its strength didn’t lift Tuowei and Great Wall, and when the funds saw trouble, they quickly liquidated—classic quant move—selling near the level line, missing the chance to profit. It was fortunate that my position control was good, so losses weren’t large, but what was initially a profit of over 2000 turned into a loss—like eating a fly!

(3) Positioning in Aerospace Development. I’ve entered this old favorite for the ninth time, always leaving with gains, hoping it will continue to reward me. Recently, funds have been clearly entering, with strong support, and big money kept firing in the afternoon, but the sector’s response was weak, lacking momentum. Still, the theme has high expectations, waiting for a breakout.

Summary: Today marked a real divergence in the electro-computation collaboration sector. Core stocks like Shun Na opened high and then declined, showing divergence. I believe divergence isn’t necessarily bad; it’s better than a rapid rise followed by divergence. It creates a buy point for funds that missed out, which is beneficial for forming a rebound rally later. Tomorrow, focus on the feedback of high-level stocks like Shun Na. If Shun Na can rebound and hit the limit-up, driving the sector back, it could resemble the later stage of Pingtan, with leaders reaching new heights and lower levels catching up. Tomorrow is a key node for the electro-computation sector; just stay focused. As for the hot crayfish concept, it still revolves around domestic computing power attributes, with some movement in large models. News stimuli will continue, and theme speculation will deepen. Friends who are optimistic can consider entering on divergence signals.**
