The S&P/ASX 200 Index (ASX: XJO) is having another poor session. In afternoon trade, the benchmark index is down 0.35% to 8,670.2 points.
Four ASX shares that are falling more than most today are listed below. Here's why these shares are tumbling:
Amotiv Ltd (ASX: AOV)
The Amotiv share price is down 4% to $6.20. This appears to have been driven by a broker note out of Citi this morning. According to the note, the broker has downgraded the auto parts company's shares to a neutral rating with a heavily reduced price target of $6.70 (from $9.30). It made the move after reducing its earnings forecasts to reflect margin pressures.
DroneShield Ltd (ASX: DRO)
The DroneShield share price is down 14% to $3.03. Investors have been selling the counter-drone technology company's shares following the announcement of an ASIC investigation. The investigation relates to announcements made between 1 November 2025 and 20 November 2025, as well as share trading between 6 November 2025 and 12 November 2025. It said: "DroneShield advised that it will cooperate fully with the investigation regarding announcements and information provided to the Australian Securities Exchange between 1 and 20 November 2025, and trading in Droneshield shares between 6 and 12 November 2025 (inclusive). […] It is not clear what action, if any, may result from ASIC's investigation."
Life360 Inc (ASX: 360)
The Life360 share price is down 12% to $17.69. This follows the release of the family safety and location technology company's first-quarter update. Life360 reported total revenue of US$143.1 million for the quarter, up 38% on the prior corresponding period. It also posted global monthly active user (MAU) growth of 17% year on year to approximately 97.8 million. And while management has upgraded its revenue and EBITDA guidance for FY 2026, it has been forced to trim its MAU guidance due to a technical issue with Android phones. MAU growth is now expected to be in the range of 17% to 20%, rather than 20%.
WiseTech Global Ltd (ASX: WTC)
The WiseTech Global share price is down 5% to $40.21. This is despite there being no news out of the logistics solutions technology company on Tuesday. However, it is worth noting that the technology sector is facing a selloff today. This has seen the S&P/ASX All Technology Index fall 3% this afternoon.
