Ondas: Why Is a Nearly Flat Stock Among the Most Shorted?

Ondas is trading 0.45% higher at $6.68, and no company release is dated today. It appears among the most shorted names because of the size of the bearish position rather than a large move: 253,887,333 shares were sold short as of October 15, up 25,341,919 from the prior period, about 44.5% of shares outstanding (calculated), with 4.57 days to cover.

Four of the names carry short interest on a shares-outstanding basis as of October 15: Ondas at 44.5%, SoundHound AI at 38.5%, Serve Robotics at about 36% and BigBear.ai at 28.5%, so Ondas sits 6.0 points above SoundHound AI and 16.0 above BigBear.ai (calculated).

Ondas has 117,390,196 more shares sold short than BigBear.ai (calculated), yet its 4.57 days to cover is 5.86 days below Serve Robotics at 10.43 (calculated), reflecting heavier trading volume. Ondas's market value near $3.81 billion is about 3.5 times BigBear.ai's near $1.1 billion (calculated).
