Sivers Semiconductors: A Fund Manager's Mea Culpa and a Trading Blackout Collide
Published on 07/26/2026 at 20:02 | Redaktion boerse-global.de
The past few weeks have been punishing for anyone holding Sivers Semiconductors stock, and the pain is now cutting across both sides of the trade. A Swedish hedge fund manager has publicly admitted defeat on a short bet against the company, while the stock itself has entered a mandatory trading blackout for insiders after a brutal sell-off that erased nearly two-thirds of its value in a single month.
Stefan Roos, who runs the Origo-Quest fund at Origo Fonder, closed his short position in Sivers back in May and now describes the wager as simply "a bad bet." The candid admission from a professional investor who makes a living betting on falling prices is striking, particularly because it comes just as the stock has collapsed. Roos was caught on the wrong side of a spectacular rally that carried the shares to a 52-week high of €10.23 on June 3, only to see them reverse course violently in recent weeks. His Origo-Quest fund dropped 20 percent in the first half of the year, with additional short positions in Powercell and Tobii also dragging on performance. On the long side, Roos has been betting on media group MTG and sold his stake in Nolato earlier in the summer.
The irony of Roos's timing is not lost on market participants. He exited his short before the stock's dramatic downturn, meaning he missed the payoff that has since materialized for anyone still holding a bearish position. The episode underscores just how difficult it has become to navigate Sivers's extreme volatility, which has wrong-footed both bulls and bears in rapid succession.
Insider Signals Diverge as Lock-Up Ends
Adding to the confusion, the company's top executives have been sending mixed messages. A lock-up agreement expired on July 16, triggering a flurry of insider activity that regulators disclosed on July 21. Chief Executive Vickram Vathulya added 70,000 shares on the open market, raising his total holdings to 4,540,076. But Chairman Bami Bastani took the opposite tack, selling 275,000 shares on the very day the lock-up lifted. Bastani also gifted 70,000 shares to family members and donated 60,000 shares to charitable organizations.
Should investors sell immediately? Or is it worth buying Sivers Semiconductors?
The boardroom split offers little clarity for outside investors trying to gauge confidence in the company's prospects. One top executive is putting more money to work; another is reducing his exposure and giving away large chunks of his stake.
Blackout Period Begins
From July 28, the picture will become even murkier. Sivers enters a 30-day "closed period" under the EU Market Abuse Regulation, which bars directors and management from trading shares ahead of quarterly results. The blackout runs until the company releases its second-quarter report on August 27, before the opening bell on Nasdaq Stockholm. The date was confirmed in an updated financial calendar on July 9, with the company noting that it has aligned its reporting with PCAOB auditing standards — a move that suggests Sivers is preparing for a potential dual listing in the United States.
During the blackout, the market will lose the insider trading signals that sometimes offer clues about management's view of the business. Instead, investors will be left to scrutinize the company's "opportunity pipeline," which management valued at $799 million as of May. Whether that pipeline translates into actual orders is a question the August 27 report may begin to answer.
The Numbers Tell the Story
The stock closed at €2.83 on Friday, down 6.35 percent on the day. Over the past 30 days, the decline has reached 60.69 percent — a pace that would be extreme for any stock, let alone one that had just completed one of the most eye-catching rallies on the Swedish market. The annualized 30-day volatility stands at 161.81 percent, a figure that captures the sheer unpredictability of the move.
Sivers Semiconductors at a turning point? This analysis reveals what investors need to know now.
The 14-day relative strength index has fallen to 35.4, edging toward oversold territory, though the stock remains far below its 50-day moving average. For long-term investors, the message is clear: Sivers has delivered both an extraordinary upside and a ferocious correction within the span of a few months, making it a trader's paradise and a buy-and-holder's nightmare.
For retail investors watching from the sidelines, the takeaway from Roos's public mea culpa is that even seasoned professionals are struggling to get the timing right. The stock's next major test arrives on August 27, when the quarterly numbers will either validate the recent sell-off or suggest that the market has overreacted. Until then, the blackout ensures that insider activity will provide no clues — and the volatility that has defined Sivers in recent weeks shows no sign of abating.
