Amentum Is Down 35% in 60 Days. What History Says Now.

Amentum Holdings Is Down 35% in 60 Days. What History Says.

Amentum Holdings, Inc. (AMTM) has officially crossed into the red zone as of May 5, 2026, marking a significant shift in its risk profile compared to the broader government services and defense contracting sector. While many peers in the aerospace and defense industry have maintained relatively stable valuations, Amentum’s current price action represents an isolated and accelerating decline. Our data shows that this transition from the yellow zone to the red zone reflects a level of selling pressure that has decoupled the stock from its immediate industry rivals.

Breaking Down the Move to the Red Zone

As of May 5, 2026, Amentum Holdings, Inc. (AMTM) carries a Drawdown Severity Score™ of 5.4. This "Strong" rating places the stock firmly in the red zone, a designation we use to identify drawdowns that have exceeded typical volatility parameters. The stock is currently trading at $24.34, which represents a 35.1% decline from its all-time high of $37.53.

The velocity of this move is particularly notable. The stock has been in a consistent drawdown for 60 days. This duration is nearly triple the asset's historical average drawdown length, suggesting that the current selling cycle is far more persistent than previous pullbacks. When a stock moves from the yellow zone to the red zone, it indicates that the Drawdown Severity Score™ has bypassed the "Moderate" threshold, signaling that the price action is no longer a standard correction.

Historical Context and the Small Sample Size Caveat

When analyzing the historical behavior of Amentum Holdings, Inc. (AMTM), we must acknowledge a limited data set. Our records indicate there have only been 2 total historical drawdown events for this ticker. In those previous instances, the average maximum drawdown was only -11.8%, with an average duration of 23 days.

The current 35.1% decline is nearly three times more severe than the historical average. Our data shows that Amentum Holdings, Inc. (AMTM) has dropped by 5% or more only 2 times in its trading history. In those specific comparable drops, the average duration was 23 days. Because the current drawdown has already lasted 60 days, we are witnessing an unprecedented period of weakness for the stock since its inception. Investors should weigh these averages carefully, as the small sample size means the stock is currently defining its long-term risk boundaries in real time.

Catalysts Behind the 35% Decline

The fundamental backdrop for Amentum Holdings, Inc. (AMTM) has been a mix of operational milestones and financial headwinds. According to TIKR.com, the stock recently fell 12% following the release of its Q1 results. While analysts cited by the same report maintain a $37 price target, the immediate market reaction to the earnings data was decidedly negative.

Other news has been more constructive but has failed to arrest the slide in the Drawdown Severity Score™. Simplywall.st recently analyzed the company’s valuation following its key role in NASA’s Artemis II mission, and Yahoo Finance reported on the company’s backlog growth and recent momentum. Furthermore, The Globe and Mail reported that Amentum successfully refinanced and expanded its senior secured credit facilities, a move often seen as a stabilizer for long-term capital structure. Despite these developments, the market has continued to reprice the stock lower, leading to the current 60-day decline.

Monitoring the Path to Recovery

For Amentum Holdings, Inc. (AMTM) to exit the red zone, we would need to see a sustained reversal in the Drawdown Severity Score™. Currently, the stock is categorized by a "Hold" consensus recommendation from brokerages, according to MarketBeat. Investors often look for a stabilization in price action before a zone change occurs.

The next major data point for the company will be its fiscal Q2 results. According to Stock Titan, Amentum is scheduled to post these results before an 8:30 a.m. call on May 12. This upcoming earnings report could serve as a volatility catalyst that either deepens the current drawdown or provides the necessary support to begin a recovery toward the yellow or green zones. We will continue to track the exact numbers to see if the stock can return to its historical average drawdown duration of 23 days or if it will continue to set new extremes in drawdown length.
