When this was written — On 10 July 2026. The figures are as at that date or earlier and have not been updated since.
While retail investors chase the slipstream of global nuclear hype, short sellers have quietly targeted the technology behind it. Silex Systems has become a battleground, its laser isotope separation process attracting more than just commercial interest from global enrichers.
The company recently celebrated the completion of its quantum silicon plant in June 1, a milestone meant to target the sub-50kg quantum computing market 12. Yet the market's reaction has been cold, with the stock sliding 16.1% over the last month alone 34. It is a stark contrast to the promotional energy that lifted the stock on broader nuclear themes earlier in the year 56. Institutional shifts have also rattled the register, notably after BNY Mellon exited as a substantial shareholder in March 78, leaving a vacuum that shorter-term traders have been all too happy to fill.
Short interest in Silex now sits at 8.52%, comfortably ahead of the peer sector average of 3.80%. Over the last 90 days, shorts peaked at 9.19%, dragging the average to 8.05%. What makes the play compelling is the 30-day price-to-short correlation of -0.338. Short sellers are not just hedging; they are actively pressing the sell button to capitalise on the stock's 43.1% drop over the past six months. This is a deliberate, negative correlation play against a stock trading at $5.07.
The laser technology may be cutting-edge, but the market's pricing is blunt. With short interest hovering near historical highs, the path of least resistance remains downward.
