Jiangbolong (301308.SZ), as it’s called locally, is deep in a hot sector. Investors are betting on AI-driven spending to keep pushing demand for storage gear, from consumer devices to data centres.
The Wind storage index tracking the sector surged 28.71% year to date through Jan. 30. Several publicly traded storage companies kicked off the week with upbeat profit forecasts. Zhang Xiaorong, head of DeepTech Research Institute, told Times Finance that “AI computing demand has been the core driver,” pointing to tight supply as major manufacturers shift capacity toward higher-end products. He also mentioned that some A-share firms benefited from inventory revaluation and price increases. Lin Meibing, chief analyst at ICTIME, warned of a “bubble” risk amid the demand spike and highlighted slow capacity growth, making short-term price swings hard to predict. (Sina Finance)
On Jan. 29, Longsys forecasted its 2025 net profit to range from 1.25 billion to 1.55 billion yuan, marking a surge of 150.66% to 210.82% over last year. Revenue is expected between 22.5 billion and 23.0 billion yuan. The company pointed to a rebound in storage prices after a first-quarter low and rising AI server demand as drivers behind the jump. It also announced it completed the first “tape-out” for its UFS 4.1 controller chip, a key step before mass production. At the same time, custom edge-AI storage products have already shipped in volume to major clients. These figures remain preliminary and unaudited; full details will come in the annual report.
The stock pulled back before the weekend, underscoring how quickly sentiment can turn in a crowded trade—even when the fundamentals look solid.
The risk is obvious: should memory prices drop or the AI infrastructure rollout lag behind expectations, the recent surge in the sector might unravel fast. When that happens, profit forecasts flip from fueling momentum to signaling a peak.
Traders are keeping a close eye on the storage sector this week, eager to see if it can regain its footing after last week’s swings. They’re also waiting on further signals from industry players to back up the bullish supply-demand story that pushed the trend higher through January.
Longsys is set to release its earnings on April 28, according to Investing.com. Investors will be keen to see how much of the recent profit jump holds up in the official numbers, as well as what the company says about Q1 demand and pricing trends. (investing.com)
