穩懋’s strong share-price move was driven by more than the broader semiconductor-sector sentiment.
Demand for high-speed optical communications used in AI infrastructure and the U.S. review of regulatory proposals have both been cited.
However, confirmed revenue, intraday share prices, and market participants’ outlooks are different types of information.
3-Line Summary
1. 穩懋 shares rose on expectations for optical communications.
2. July revenue was NT$18.92 billion.
3. Regulatory benefits and earnings outlooks are not confirmed.
A 26.06% Gain in 5 Trading Days, Larger Than the Sector
穩懋 is a semiconductor-sector stock listed as 3105-TW. 鉅亨網 reported that during the morning session on September 1, the stock rose 3.89% in five minutes to NT$466.5. Trading volume at the same time was 13,123 lots (3123), while the intraday gain for the day was reported as 4.36%.
That figure describes an intraday move during a single day. By contrast, the same report stated that the recent 5-trading-day gain was 26.06%. During that period, a semiconductor-related index rose 2.96%, while the weighted index of the over-the-counter market rose 4.04%. This is why the comparison says 穩懋’s gain was larger than that of both indexes. However, this comparison alone does not establish that one specific cause fully explained the share-price increase.
Recent five-trading-day flows showed net buying. The combined net purchases by the three institutional investor categories totaled 16,233 lots (6233). Foreign investors recorded net purchases of 5,806 lots (5806), investment trusts 8,990 lots (8990), and proprietary trading desks 1,437 lots (1437), while the margin-trading purchase balance increased by 930 lots. These figures describe publicly reported trading activity during that period; they do not mean that the same buying momentum will continue afterward.
The location in which the share-price rise occurred can be confirmed only from intraday reporting on Taiwan-listed stocks. The fact that this keyword was observed in Taiwan’s search market does not mean that the U.S. regulatory review or optical-communications demand originated in Taiwan. Rather than treating the location and the events as one package, they should be examined separately within the scope of each report.
Optical Communications at the Center of July’s Record Revenue
FTNN 新聞網 introduced 穩懋 as a gallium arsenide wafer foundry. According to the outlet, July revenue was NT$18.92 billion. It rose 7% from the previous month and 31.2% from the same month a year earlier, reaching a four-and-a-half-year high. Cumulative revenue from January through July was NT$117.39 billion, up 33.4% year over year.
The change highlighted in the report was the share of businesses outside mobile phones. As demand for high-speed optical communications increased with the expansion of AI infrastructure, revenue from optical products rose to the high single digits as a percentage of total revenue. FTNN 新聞網 reported that this share had grown several times compared with the previous year. This does not mean the share has already exceeded half, but it does confirm the context that the product mix is expanding beyond mobile phones.
The company expects the share of optical products to continue increasing in the second half of the year, further improving its product mix. This is the company’s outlook, not a confirmed fact about second-half revenue. Upgrades to 800G and 1.6T, along with growth in demand for silicon photonics and satellite applications, were also cited in the report as potential future drivers. The report did not specify which item would convert into revenue, when, or to what extent.
Regarding China’s controls on indium phosphide (InP), the company also said there were no supply problems. It stated that cooperation with major companies in Europe, the United States, and Japan was ensuring smooth raw-material supplies. This, too, is the company’s account of its supply situation. The report did not provide details of the controls or future supply conditions.
The U.S. Regulatory Proposal and Third-Quarter Outlook Are Not Results Yet
UDN reported that the U.S. government was drafting a ban that would prevent new optical-fiber transceivers from mainland China from being shipped to the United States. Market participants cited in the report viewed the measure as potentially intended to protect AI infrastructure in the United States. Expectations were also raised that 穩懋 could be a major beneficiary, given that many of its PIN-related optical-communications orders come from U.S. customers.
The first distinction to make is between drafting a ban and an implemented ban. The information provided concerns the stage at which the U.S. government is preparing a regulatory proposal and the market’s expectations of potential beneficiaries. It has not been confirmed whether the proposal will be finalized, when it would take effect, or which products and transactions it would cover. It is therefore difficult to interpret it as an already realized increase in revenue or a confirmed competitive advantage.
The corporate outlook reported by FTNN 新聞網 should be viewed in the same context. Mobile-phone and Wi‑Fi demand is expected to be broadly flat in the third quarter, but quarterly revenue could increase by double digits, supported by growth in the Infrastructure and Optical businesses, while the gross margin could approach 30%. This is the corporation’s estimate. It is not the announced result for the third quarter.
UDN also reported that one institution issued a “buy” recommendation while forecasting 2026 earnings per share at NT$7.5, up from NT$4 last year. The warrant issuer proposed purchasing related call warrants. Both statements reflect the judgments of the institution and the issuer; neither guarantees the company’s actual earnings or investment results.
What has been confirmed in this movement is the increase in July revenue and the share-price changes during the day and over the latest five trading days. The expansion of the optical-communications share, the third-quarter growth rate, and the benefits of U.S. regulation differ in both strength and degree of certainty. When assessing 穩懋, it is more accurate to separate confirmed revenue from the outlook that remains unverified than to focus on the size of the expectations.
