Why AMTM stock is down today

Amentum Holdings Inc. shares fell 5.59% in afternoon trading to $20.27 after two major price target cuts from analysts. The stock opened at $21.57 and reached a high of $21.64 before declining throughout the session. The move reflects reduced optimism from key institutions covering the stock.

What Happened

JPMorgan and RBC Capital both lowered their price targets for Amentum. JPMorgan cut its target to $26 from $31, while RBC Capital reduced its target to $26 from $28. Both firms maintained their overall ratings, JPMorgan with a Neutral stance and RBC with a Sector Perform. These adjustments came within a 36-hour period and were highlighted by The Fly. UBS also revised its target upward to $24, while BTIG cut its target to $30 but maintained a Buy rating. The stock has a market cap of $5.8 billion and a P/E ratio of 26.1, with trailing 12-month revenue up 26.1%.

What The Data Shows

The stock traded at 0.8 times its 3-month average volume of 1.6 million shares. It reached a session low of $20.27 at 2:50 PM ET and closed the day at that level. The 52-week range is $19.80 to $38.11, and the stock has printed 26 fresh 52-week lows on August 17. Retail traders have mentioned the price target cuts on social media, with some on X calling the move bearish. Recent congressional trades include a buy and a sell by Donald J. Trump, both within the $15,001-$50,000 range, but no clear pattern has emerged.
