Sivers Semiconductors: Hedge Fund Short Collides With Retail-Driven Rally
Published on 08/09/2026 at 02:51 | Redaktion boerse-global.de
The Swedish chipmaker's stock has become a battleground between institutional skepticism and social-media-fueled retail enthusiasm. On Wednesday, D. E. Shaw & Co. disclosed a net short position of 0.59 percent to the Swedish financial regulator, dated August 2 — a bet against a stock that had just surged 36.07 percent in seven trading days.
The timing underscores the schizophrenic nature of trading in Sivers Semiconductors. Friday's session saw shares close at EUR 3.75, up 13.64 percent on the day, after an anonymous X account touted the company as "the next Lumentum." Media reports characterized the move as part of a broader retail-driven rally, though commentators were quick to note that Lumentum itself is an obscure laser maker trading on heavily priced-in growth expectations. The comparison fired up speculative interest without any new operational data from Sivers to back it.
A Stock Still Deep in the Red
Even after Friday's jump, the shares remain 63.34 percent below their 52-week high of EUR 10.23, reached in early June. That gap between recent momentum and prior peaks is precisely the kind of environment where contrarian institutional bets thrive — and where retail enthusiasm can collide head-on with professional caution.
The company's capital structure has shifted meaningfully in recent weeks. Late July saw Sivers report an increase in total outstanding shares and votes to 355,081,317, following a directed share issue of 12,280,701 new shares and the conversion of a shareholder loan from Bootstrap Europe IV SCSp into 22,847,044 new common shares. The underlying capital raise had closed in early July, with institutional investors subscribing at SEK 57 per share and injecting roughly SEK 700 million into the company. Proceeds are earmarked for expanding production capacity for indium phosphide lasers and optical amplifiers.
That placement was multiple times oversubscribed, with both Swedish and international institutions participating, and represented dilution of approximately 3.3 percent of share capital.

Insider Activity Sends Mixed Signals
The post-lock-up period has produced a decidedly mixed picture on the insider front. Board members — including Bami Bastani, Karin Raj, Helena Svancar, Todd Thomson, and Joakim Nideborn — made purchases on July 13 that were approved at the June general meeting, subject to a twelve-month holding period that precludes quick exits.
CEO Vickram Vathulya added 70,000 shares to his position roughly three weeks ago, bringing his total to 4,540,076 shares. The stock has since recovered 21.0 percent. Bastani, meanwhile, sold 275,000 shares on July 16, donated 60,000 to charities, and gifted 70,000 to family members — while retaining 381,360 shares and 625,000 employee options. Headwaters Capital LLC, associated with board member Thomson, disposed of 950,000 shares by July 22 and transferred 50,000 to a charitable organization.
The divergent strategies offer investors little directional clarity, though the volume of activity around the stock is itself notable.
Correcting the Record
The insider moves come against a backdrop of at least one significant error. On July 24, a report circulated that Vathulya had sold 1,233,761 shares. Sivers fully retracted that claim after official filings with the Swedish Finansinspektionen confirmed no such transaction had ever taken place. The company said the original notification should be treated as void.
A History of Turbulence
June brought a critical report from research firm Ningi Research, which accused Sivers of "dubious revenue recognition, hollow customer contracts, and broken promises of an imminent volume ramp since 2018," calling the rally a speculative, retail-driven bubble. Shares traded on US over-the-counter venues fell 9.2 percent in response. The Rosen Law Firm subsequently announced an investigation on behalf of Sivers shareholders into potentially misleading business information.
The fundamentals remain under pressure. First-quarter 2026 net revenue fell to SEK 61.9 million from SEK 78.9 million in the year-earlier period, a decline of 22 percent. Adjusted EBITDA deteriorated to minus SEK 13.8 million from minus SEK 6.0 million. Management cited the US government shutdown in Q4 2025, delayed defense budgets, and unfavorable currency effects, while spending increased on sales efforts and preparations for a potential New York listing.

What's Next
August 27 is the key date on the calendar. Sivers will publish its Q2 2026 interim report before trading opens on Nasdaq Stockholm — later than the early August date originally planned. The company cited additional time needed to align financial reporting with PCAOB audit standards, a prerequisite for the planned dual listing on the Nasdaq.
A closed period under the Market Abuse Regulation has been in effect since July 28, which should quiet the news flow until the report lands. Whether the stock itself quiets down is another matter entirely. With a hedge fund short, a retail-driven narrative, and a delayed earnings report all in play, the ingredients for continued volatility are very much in place.
