The defense drone complex is selling off together on Thursday morning, and the shape of the move matters more than the headline attached to it. Ondas Holdings (NASDAQ:ONDS) stock is down 7% to $8.31, while Unusual Machines (NYSE:UMAC) stock is down 8% to $26.13.
Meanwhile, Red Cat Holdings (NASDAQ:RCAT) stock is down 5% to $9.36, and Kratos Defense & Security Solutions (NASDAQ:KTOS) stock is down 5% to $57.61. Four names that entered the day with wildly different year-to-date setups are all falling by similar amounts, which points to positioning as the driver.
That pattern reverses what held earlier in the week, when Ondas Holdings and Red Cat Holdings shares held their ground during a Nasdaq pullback and the drone complex looked like a rotation destination. Today the group is doing the leading, and in the wrong direction.
Tariff Headline Fits the Story but Not the Size
China called on the United States on Thursday to reverse Section 232 tariffs on imported drones and related components, a policy that sits over every name in this group, including Ondas Holdings and Kratos Defense. He Yadong, a spokesperson for China’s Commerce Ministry, stated in Beijing that the measures “treat related Chinese products in a discriminatory manner and seriously harms the interests of Chinese companies.”
Those tariffs stem from a proclamation President Trump signed on August 13 imposing duties of up to 100% on imported drones and unmanned aircraft components, with most rates taking effect after 21 days. Chinese President Xi Jinping visits the United States on September 24, giving Unusual Machines and Red Cat Holdings shareholders a defined window for the dispute to shift.
All four names barely reacted to the news itself. Ondas Holdings, Unusual Machines, and Kratos Defense each moved lower by less than 1% in early Thursday trading, and Red Cat Holdings traded higher. Declines of 5% to 8% developed only once the regular Thursday session was underway.
Opposite Setups, Same Selloff
The cleanest evidence that this is a theme unwind sits in the year-to-date (YTD) scoreboard. Through Wednesday’s close, Unusual Machines stock was up 122%, one of the largest gains in the small-cap defense complex, while Kratos Defense stock came into Thursday down 20%. Opposite positions entirely, and both are falling by roughly the same amount today.
Red Cat Holdings stock was up 25% YTD heading into the session, and Ondas Holdings stock was down 9%. When names with opposite setups and different fundamentals move as a single block, the tape is telling investors that a theme is being unwound at the group level.
Macro conditions reinforce that read. The 30-year Treasury yield sits at 5.28%, near a 19-year high hit earlier this week, and high-multiple momentum names carry the most sensitivity to a rising long-end discount rate. Ondas Holdings stock trades at a price-to-sales ratio near 29, and Unusual Machines stock trades at roughly 44 times sales, so both sit squarely in the crosshairs of that repricing.
What to Watch Now
Traders may want to keep an eye on whether the group finds a bid into the afternoon or extends losses on rising volume, since the same flows dynamic that drove the morning drop can compound if late-day sellers keep trimming exposure. Options positioning already leans defensive, with the Ondas Holdings October 2 $6.5 put showing a volume-to-open-interest ratio of 16, and the Red Cat Holdings October 2 $10 put ratio sitting above 18.
The takeaway for position sizing is straightforward. When a theme trades as a single block, owning ONDS, UMAC, RCAT, and KTOS together provides far less diversification than four separate tickers on a brokerage statement would suggest (we wrote a whole free playbook on speculating with a small slice of a portfolio and sizing it with real rules, here). Shareholders carrying overlapping drone exposure across the four should size the group as a single position, not four independent ones, until the correlation breaks and these names start trading on their own catalysts again.
