Exail Technologies is retreating 8% in Paris, hit by an announcement from Donald Trump claiming that Iran "with the help of the United States, has removed, or is in the process of removing, all of the sea mines" from the Strait of Hormuz, ahead of its imminent reopening.

The stock had gained 8.5% over the month, sought after by investors who anticipated that Exail and its underwater detection technologies would be called upon to detect and identify mines placed in the passage. Donald Trump's announcement effectively undermines this thesis.

According to our data, Exail Technologies is currently among the five most shorted French stocks, with an estimated short interest of 8.21% of its share capital in terms of visible positions—referring to short funds holding 0.5% or more in bearish bets. Seven funds have been identified, the largest being Qube Research with a .84% stake.
