- MicroAlgo jumped 39.95% to finish at $5.36 after its quantum image-processing news.
- The stock traded as high as $6.87 in the session, with volume at roughly 9.74 million shares, much heavier than its usual 447,270-share average.
- The company hasn’t said it landed a customer, set a revenue target, or launched a commercial rollout for the algorithm.
MicroAlgo Inc. stock surged 39.95% Wednesday after the Shenzhen-based algorithm developer announced a proposed quantum image edge-extraction algorithm for noisy images. The news fueled heavy trading in MLGO, a small-cap name known for big swings. Shares finished the day at $5.36 after hitting $6.87 earlier, then dipped to $5.22 in after-hours trading, which means trades after the closing bell.
MicroAlgo shares popped after a technical update, not on earnings or any new deal. The company said it has built a way to use quantum computing and digital image processing to sharpen noisy images and pick out edges faster.
Trading was heavy. Shares traded at 9.74 million compared to the usual 447,270, and the market cap ended close to $66.7 million, Google Finance data showed. Swings like that push price discovery off course in stocks that don’t see much attention.
MicroAlgo said the algorithm takes pixel grayscale and location and puts them into quantum states, letting it process the data in parallel. The company also pointed to a dual filtering method and adaptive thresholding, which sets which edges to keep in images without needing manual controls.
MicroAlgo laid out a wide set of possible applications, from factory inspection and medical imaging to financial risk and traffic management. The statement skipped any actual customer names, revenue forecasts, patent filings or when a commercial launch might happen. The company said it plans to keep refining the technology and to push forward on integrating it with quantum hardware.
Market sentiment got a lift from the broader tape. U.S. stocks climbed Wednesday, with the S&P 500 advancing 1.1% and the Nasdaq composite gaining 1.5%. Bond yields pulled back and oil prices dropped, according to the Associated Press.
D-Wave Quantum added nearly 6%, Rigetti Computing was up 5.7% and Quantum Computing Inc. picked up 3.6% in late trading, but those gains were modest next to MicroAlgo, which had a much bigger and more isolated move.
MicroAlgo is a holding company. Its subsidiaries work on custom central processing algorithms, Reuters’ company profile shows. Their services link to internet ads, gaming, computing acceleration, data processing and smart chips.
MicroAlgo’s recent numbers look better than the stock’s long-term chart. In an April filing, the firm reported 2025 revenue of RMB 422.05 million, or $60.05 million. Net profit jumped 143.5% to RMB 127.56 million, or $18.15 million. CEO Min Shu said MicroAlgo kept stable cash and liquidity while delivering “strong growth in net profit.”
Wednesday’s rally may be getting ahead of itself. A research update can send a speculative tech name higher, but no revenue and no customers means investors have little to go on about when, or if, that tech will turn commercial. Even now, the stock is still about 93% under its 52-week high of $78.90, despite the pop.
After the bell, trading risk picks up. Nasdaq notes after-hours trading is from 4 p.m. to 8 p.m. Eastern, and traders can see bigger price swings and thinner volumes, with fewer buyers and sellers. That’s an issue for MLGO, which traded in a range from $3.79 to $6.87 today but finished far off its highs.
