Investment Highlights Why It Matters Which of these 2 stories sounds closer for this stock?

1. Generates cash flow

The stock generated 4% or more of the share price (called cash flow yield), and shows moderate 10-15% or more growth.

2. Riding a trend

Think Tesla during the pandemic of 2020 when EVs were riding a cultural high, or Nvidia in the current AI boom, or even Figma. These companies don’t have enough yield, or, enough growth, or both - however - they are riding a trend. They have momentum. These can be more volatile - they don’t have the floor of strong cash flow

AI Generated Analysis | Feedback

1. Positive Clinical Trial Data from iMMagine-1 Study.

Arcellx reported compelling preliminary data from its Phase 2 pivotal iMMagine-1 study of anitocabtagene autoleucel (anito-cel) for relapsed or refractory multiple myeloma (RRMM) on August 7, 2025. The data indicated a 97% overall response rate (ORR) and a 68% complete response/stringent complete response (CR/sCR) at a median follow-up of 12.6 months. Importantly, the study also highlighted a favorable safety profile with no observed delayed neurotoxicities, which included no Parkinsonism, cranial nerve palsies, or Guillain-Barré syndrome. Further reinforcing this, an August 28, 2025 report detailed a 93.1% minimal residual disease (MRD)-negative response rate, with more than 150 patients treated and long-term data confirming strong efficacy and tolerability.

2. Strong Analyst Endorsements and Increased Price Targets.

Arcellx received significant positive attention from research firms during this period. On July 31, 2025, Scotiabank maintained its "Buy" rating and raised its price target for Arcellx to $133 from $93. This positive sentiment continued with Stifel initiating coverage on October 16, 2025, with a "Buy" rating and a price target of $129, emphasizing the potential of anito-cel to become a leading BCMA-targeting CAR T therapy. Canaccord Genuity further boosted confidence on November 3, 2025, by raising its price target to $130 from $121, while maintaining a "Buy" rating, citing anticipated higher U.S. launch revenues from anito-cel therapy.
