BLT (688333) Sees Net Institutional Selling of 9.69 Million Yuan on April 28 Amid Strong Revenue Growth

BLT (Bright Laser Technologies, 688333) experienced net institutional selling of 9.69 million yuan on April 28, 2026, according to exchange data. The stock closed at 83.6 yuan, down 2.11% for the session, with total trading volume of 5.8 billion yuan. The institutional outflow represented 1.67% of total turnover, while retail investors contributed a net inflow of 248.26 million yuan. This selling pressure comes despite BLT reporting strong first-quarter 2025 results: operating revenue of 1.161 billion yuan, up 46.47% year-over-year, and net profit attributable to shareholders of 156 million yuan, a 234.83% increase.

This institutional profit-taking pattern fits the Chinese localization arc (P2) within the broader metal AM industry. BLT, as China's dominant metal LPBF system manufacturer and service provider, has been scaling rapidly on domestic defense and aerospace demand, a segment that has seen politically accelerated adoption since 2025. The selling is not a fundamental signal against the company's trajectory — BLT's revenue growth and margin expansion (43.48% gross margin) are among the strongest in the global metal AM sector. Rather, it reflects typical institutional rebalancing after a sustained run-up, as the stock has been a high-beta beneficiary of China's self-sufficiency push in industrial 3D printing. The company's integrated business model — covering materials, machines, and part services — gives it a structural advantage over Western peers who often separate hardware from service revenue.

For analysts tracking BLT, the institutional outflow is a short-term liquidity event, not a deterioration in the company's competitive position. The key execution metric to watch remains BLT's ability to convert its strong order backlog — driven by aerospace and defense programs — into recurring service revenue, which carries higher margins than pure machine sales. The company's 46.47% revenue growth in Q1 2025 suggests demand remains robust, but investors should monitor whether the pace of new machine installations can sustain this trajectory as the domestic market matures. No change to the fundamental thesis: BLT remains the bellwether for China's metal AM industrialization.
