It's been a while since I've shared anything seriously, so I'll just jot down some random thoughts. If you ask me what I'm currently holding and particularly optimistic about, I'd like to start by talking about Tianyin Electromechanical (300342). First, looking at the background, SpaceX's IPO application and planned fundraising are highly likely to set a record for the world's largest IPO (on March 25th, last Wednesday, The INF reported that SpaceX plans to submit its IPO application to regulators soon, aiming for a listing in June this year, with an expected fundraising of over $75 billion). It was around that time that I discussed this with a friend and chose to buy Tianyin, around 47. Of course, Tianyin Interstellar had previously explicitly stated on the Shenzhen Stock Exchange that it has no business cooperation with SpaceX and no direct supply. The reason I chose to buy at the time was simple: I firmly believed that the aerospace industry would soon usher in a second wave, and that China's low-Earth orbit was about to experience explosive growth. 1. The news background: SpaceX's IPO will draw more attention to investment opportunities in commercial spaceflight (IPO progress news can evolve at any time). 2. The Starship test flight in April will also ignite sentiment in the aerospace sector (the first half of 2026 will see a very concentrated series of test flights). 3. Considering the domestic reusable rocket launch schedule and the possibility of breakthroughs (such as the Lijian-2 rocket, the FAA's latest flight warning and the establishment of a critical zone, DDDD, and the imminent launch of multiple low-Earth orbit satellite small-batch network deployment missions). From the news to today, the entire sector has been experiencing low-pressure fluctuations (I personally feel this is intentional suppression), maintained for nearly a week. Therefore, a catalyst is needed. And in my opinion, a miracle is coming soon. Tianyin, as the sole supplier to Qianfan, deeply tied to China's StarNet, with orders already booked until 2030... a high-quality company that successfully transformed from refrigerator components to aerospace. It can be said that whenever there is a batch launch of national-level low-Earth orbit satellites each month, the sector will inevitably move, and Tianyin will inevitably benefit. If funds start speculating on the expansion of the international satellite industry chain, Tianyin will have the greatest potential for growth. Some expectations: Aside from various test flights, other factors include: the release of the annual report and Q1 financial report in April, which will confirm whether the 2025 target has narrowed; the potential for improvement in gross profit and cash flow from the transformation; whether the new Changshu base's production capacity will be sufficient to meet subsequent large orders after it comes online in May; intensive research by various securities firms, leading to frequent research reports; confirmation of a turnaround to profitability in the 2026 interim report in June (?), shifting from speculative themes to strong performance support, allowing for valuation repair; official announcements of the launch plans for Qianfan and Xingwang, etc. These are just my humble opinions.
