Sivers Semiconductors: Chairman Trims Stake While Short Sellers Circle a Stock in Turbulence

CEO buys, chairman sells, D.E. Shaw shorts Sivers amid 178% volatility and retail surge.

The diverging paths of insider trades and institutional positioning at Sivers Semiconductors are painting a complicated picture for investors in the Swedish chip developer. Company leadership is moving in opposite directions with their own holdings, while a major US hedge fund has just taken a bearish stance — all against a backdrop of extreme share price volatility that has become the stock's defining characteristic.

Insider Activity Points in Two Directions

Chief executive Vickram Vathulya added 70,000 shares to his position on 21 July, a purchase that came just days after a lock-up period expired on 16 July. The timing suggests the CEO is willing to put fresh money to work now that restrictions have lifted. In stark contrast, chairman Bami Bastani sold 275,000 shares and transferred another 130,000 as a gift during the same window. The opposing moves leave shareholders without a unified signal from the top — the CEO buying while the chairman reduces exposure is hardly a ringing endorsement of the company's near-term prospects.

That said, the board has shown a longer-term commitment elsewhere. On 13 July, several directors including Bastani, Karin Raj, Helena Svancar, Todd Thomson and Joakim Nideborn completed share purchases that had been approved at the annual general meeting in June 2026. Those acquisitions come with a twelve-month holding period, meaning the shares cannot be sold until at least mid-2027 — a structure designed to lock in the leadership team's engagement over a meaningful timeframe.

A New Short Enters the Fray

The insider dynamics are now compounded by fresh bearish positioning from across the Atlantic. D. E. Shaw & Co. disclosed a net short position of 0.59 percent in Sivers Semiconductors on Tuesday, making the US trading house the latest institutional player to bet against the stock. The timing is notable: it comes amid a week of violent price swings that have left even seasoned traders struggling to keep up.

Wednesday saw the shares tumble 8.52 percent to EUR 3.16, following a close of EUR 3.45 the previous day. Yet that drop sits oddly within a seven-day period that still shows a gain of 30.20 percent. The whipsaw action underscores just how far outside the norm this stock has moved — the annualized 30-day volatility stands at a staggering 178.76 percent, a figure that would be remarkable for any technology company, let alone one of Sivers' size.

Retail Piles In While Institutions Head for the Exits

Perhaps the most telling divergence is playing out between different classes of investors. Swedish retail participation has surged dramatically this year: at online brokers Avanza and Nordnet, shareholder counts have jumped from 16,000 to 23,000 and from 1,900 to 5,400 respectively. Meanwhile, Swedish pension institutions have been net sellers, cutting their positions by 83 and 97 percent over the past six months, depending on the fund. The baton has been passed to international investors — foreign ownership of Sivers Semiconductors has exploded from 14.4 percent to 80.8 percent, suggesting the recent price action is increasingly driven by overseas participants while domestic professionals take profits.

The stock's technical position remains fragile despite last week's recovery. The shares trade 41.80 percent below their 50-day average of EUR 5.42, with a 30-day decline of 25.14 percent. The market capitalization stands at roughly EUR 825.02 million, though that figure can shift dramatically within days given the current turbulence. A relative strength index of 43.3 suggests the stock is neither overbought nor oversold at present — a surprisingly neutral reading for a name with this much movement.

Q2 Report Looms as the Next Catalyst

With the second-quarter report scheduled for 27 August, followed by the third-quarter release on 26 November and the full-year results on 25 February 2027, the immediate focus is on the upcoming numbers. The quarterly update arrives in just over three weeks and will offer the clearest test of whether the operational story can justify the recent insider buying — or whether the chairman's decision to trim and the new short position from D. E. Shaw carry more weight.

An automated analyst rating compiled in early August currently sits at "Sell" with a twelve-month consensus price target of SEK 11.29. That assessment, derived from a quantitative aggregation of multiple analyst opinions rather than a single independent house view, adds another layer of caution to the mix. For now, Sivers Semiconductors remains a stock for the risk-tolerant — one where double-digit daily moves are the norm and where the gap between retail enthusiasm and institutional caution has rarely been wider.
