Sivers Semiconductors: Insider Trading Split Deepens as Lock-Up Period Lifts
Published on 07/25/2026 at 07:21 | Redaktion boerse-global.deThe expiration of a three-month trading ban on insider transactions at Sivers Semiconductors has laid bare a sharp divide within the company's leadership, sending the stock into a tailspin that has erased more than 60% of its value over the past month.
The Swedish chipmaker's shares closed at €2.80 on Friday, down 6.67% on the day, after a lock-up agreement tied to a roughly SEK 700 million directed share issuance in April expired on July 16. The restriction had barred management and board members from trading their holdings — and once it lifted, the divergence in their actions was immediate.
Chairman Bami Bastani moved aggressively to reduce his exposure, selling 275,000 shares on the very day the lock-up ended. He also transferred 60,000 shares to charitable organizations and gifted another 70,000 to family members. After these transactions, Bastani retains 381,360 shares, of which 11,360 are subject to a new one-year lock-up. Board member Todd Thomson went even further: through his investment vehicle Headwaters Capital, he sold 950,000 shares by July 22 and donated 50,000 more to a charity. Thomson remains the largest shareholder among board members with 477,027 shares. Separately, Kairos Ventures, which Thomson represents on the board, liquidated the shares it acquired through the Mixcomm acquisition in 2022, citing a fund-level decision to distribute proceeds to investors.
In stark contrast, CEO Vickram Vathulya bought 70,000 additional shares, increasing his total holdings to more than 4.5 million shares, on top of 3.7 million employee options.
Should investors sell immediately? Or is it worth buying Sivers Semiconductors?
The conflicting signals from the top rattled the market. The stock plunged 8.08% on Thursday, followed by the additional 6.67% drop on Friday. Over the past seven trading days, the decline totals 11.45%, and the one-month slide stands at roughly 61%. At Friday's close, the shares are trading 72.63% below their 52-week high of €10.23, reached in early June.
Despite the severity of the sell-off, there are tentative signs of stabilization. The short interest ratio has fallen to approximately 2.76%, suggesting that many bearish bets have already been closed out following the sharp correction. Technical indicators also point to oversold conditions: the 14-day relative strength index sits at 35.3, creeping toward the classic oversold threshold of 30. The stock now trades more than 50% below its 50-day moving average of €5.95 — a measure of just how brutal the recent rout has been.
Investors hoping for further insider signals will have to wait. Starting July 28, Sivers Semiconductors enters a 30-day closed period under Article 19(11) of the EU Market Abuse Regulation, during which persons discharging managerial responsibilities are prohibited from trading the company's securities. The next major catalyst will be the second-quarter earnings report, scheduled for release on August 27 before the start of trading on Nasdaq Stockholm.
Sivers Semiconductors at a turning point? This analysis reveals what investors need to know now.
Until then, the stock's direction will likely hinge on technical stabilization and the broader sentiment surrounding the photonics and AI infrastructure sectors, where Sivers operates. The capital raise that triggered the lock-up — 12,280,701 new common shares placed at SEK 57 each — was multiple times oversubscribed by Swedish and international institutional investors, underscoring that the company retains significant institutional support even as its leadership sends mixed messages.
