Sivers Semiconductors: A Political Shockwave From Washington Collides With a Bullish Analyst Bet
Published on 08/04/2026 at 19:41 | Redaktion boerse-global.de
The optics sector woke up to a geopolitical jolt on Tuesday, and a small Swedish chipmaker found itself riding the wave. Sivers Semiconductors surged more than 17 percent to EUR 3.40, a sharp rebound from Monday's close of EUR 2.90, after Reuters reported that the Trump administration is preparing to block imports of Chinese optical transceivers destined for US data centers.
The move, still in its formative stages, is being shaped by the Federal Communications Commission, which is drafting rules aimed at halting shipments of the components. Washington's stated rationale centers on protecting American AI infrastructure from data theft, malware, and interference. A final decision is expected before year-end, though the Reuters sources cautioned that the plan remains fluid and could be altered or abandoned entirely.

The China Factor and a Sector-Wide Rally
At the heart of the proposed ban is Zhongji Innolight, a Chinese manufacturer that commands roughly 27 percent of the global data-center transceiver market and generates an estimated 90 percent of its revenue outside China. The company was added to a US Defense Department list in June, and Beijing has already signaled it would take "all necessary measures" if American actions cause significant damage.
The ripple effects were immediate and pronounced across the US competitive landscape. Applied Optoelectronics jumped as much as 20 percent in pre-market trading, Coherent climbed up to 18 percent, Lumentum advanced 14 percent, and Corning added around 8 percent. Sivers, though not explicitly named as a direct beneficiary in the reports, was swept up in the sector-wide enthusiasm — a reflection of its status as a smaller European player in the optical components space.
Should the ban materialize, US cloud giants including Amazon, Microsoft, Google, and Meta would likely need to pivot to alternative suppliers, a shift that analysts say could drive up near-term costs for data-center expansion.
A Bullish Counterpoint Emerges
The political catalyst arrives alongside a notably upbeat assessment from an independent research voice. Serenity Analysis, in late July, characterized Sivers as a "once-a-generation long" — a rare, long-term buying opportunity. The analyst drew a direct comparison to Lumentum, positioning Sivers as a kind of "Mini-Lumentum" built around co-packaged optics (CPO) technology and silicon photonics. While no specific price target was issued, the firm projected a revenue pipeline of USD 453 million over the coming years and highlighted a planned capacity expansion with manufacturing partner Win Semi.
Adding weight to the thesis, Morgan Stanley reportedly counts Sivers among the top three producers of CPO lasers, a technology increasingly viewed as the industry's answer to surging bandwidth demands from data centers and AI infrastructure. An updated assessment from Monday maintained the "high-risk, bullish" stance with neutral price momentum and a signal score of 154, though the firm acknowledged a thin current news flow.
The Other Side of the Trade
Yet even as bullish voices grow louder, the skeptical camp is making its presence felt. D. E. Shaw, the US investment firm, has emerged as a new public short seller in Sivers, building a position equivalent to 0.59 percent of share capital — roughly 2,094,980 shares. Sweden's Finansinspektionen requires disclosure at 0.1 percent of capital, with public reporting triggered at the 0.5 percent threshold. Total short interest in the stock currently stands at 2.57 percent of capital, with no other publicly disclosed short sellers on record.
The Tuesday surge does little to alter the broader picture of the past several months. The stock remains approximately 67 percent below its 52-week high of EUR 10.23, reached in June. Swedish business daily Dagens Industri has noted that the shares had already lost more than 70 percent from that peak, with many retail investors having entered during the hype phase while the company's own analyst had recommended selling early on.

Volatility as the Defining Feature
The numbers tell a story of extreme swings. Over the past 30 days, the stock shed nearly 19 percent, only to gain more than 31 percent within the last seven. Serenity's own analysis points to a 30-day decline of close to 30 percent before the recent recovery. Pre-market trading on Tuesday saw the shares at EUR 3.01, up 3.58 percent, before the session's fuller rally took hold — still a staggering 70.62 percent below the June peak.
Supporting the longer-term narrative, Serenity also flagged earlier milestones: a grant under the Microelectronics Commons initiative in May and inclusion in the Nasdaq Stockholm index shortly thereafter. These data points feed a story of a small but technologically relevant player in the photonics segment, with applications ranging from data centers to sensing — provided the projected revenue pipeline actually materializes.
For investors, the equation remains demanding. On one side sits an ambitious growth narrative backed by external analysts and prominent industry comparisons. On the other, a stock whose recent history is defined by dramatic drawdowns and sharp recoveries, caught between enthusiastic retail participation and institutional short sellers. Tuesday's jump, driven by a Washington policy signal rather than company-specific news, is less a fundamental turning point than another chapter in an extraordinarily volatile trajectory — one where the bull case and the bear case are both being placed with conviction.
