In afternoon trade, the S&P/ASX 200 Index (ASX: XJO) has followed Wall Street's lead and dropped deep into the red. At the time of writing, the benchmark index is down 1.6% to 7,731 points.

Four ASX shares that are falling more than most today are listed below. Here's why they are tumbling:

Amotiv Ltd (ASX: AOV)

The Amotiv share price is down almost 17% to $7.32. Investors have been selling this auto parts retailer's shares following the release of a trading update. It said: "The Group now expects marginal revenue growth and a marginal decline in underlying EBITA in FY25 compared to pcp, predominantly driven by LPE (specifically Australian reseller demand) and to a lesser extent 4WD." This has nothing to do with US tariffs, with the company highlighting that its "current revenue exposure to the US is ~8% of total revenue."

Breville Group Ltd (ASX: BRG)

The Breville Group share price is down 9.5% to $27.22. This appliance manufacturer's shares have been sinking since the announcement of US trade tariffs. Yesterday, the company noted that it "currently manufactures approximately 90% of its products, by value, in China with the rest coming from the EU, Mexico and Taiwan and sells approximately 45% of its products into the United States." This means it could be heavily impacted by these tariffs. Though, it remains unclear just how significant the impacts will be.

Life360 Inc (ASX: 360)

The Life360 share price is down 7% to $18.50. This follows a brutal selloff on Wall Street overnight with tech stocks feeling the brunt of the market's wrath. The selling was so bad that the Nasdaq lost 6% of its value during last night's session. This has led to the S&P/ASX All Technology Index dropping by over 4% on Friday.

Woodside Energy Group Ltd (ASX: WDS)

The Woodside share price is down 7% to $20.82. Investors have been selling this energy producer's shares after oil prices crashed overnight. Oil prices were down 6% after eight OPEC producers announced plans to accelerate crude oil production increases. According to CNBC, the May hike agreed on Thursday is the equivalent to three monthly increments. Output will increase by 411,000 barrels per day in May. The group was widely expected to implement an increase of just under 140,000 barrels per day next month. Though, it concedes that the gradual increases may be paused or reversed subject to evolving market conditions.
