Investing.com - Ideaya Biosciences (NASDAQ:IDYA) shares fell 14% on Tuesday despite the company presenting positive clinical updates across three programs during its R&D Day.

JMP Securities reiterated its Market Outperform rating on Ideaya with a $45.00 price target, noting the company shared encouraging data from its Phase 2 neoadjuvant UM brachytherapy study, DLL3 ADC Phase 1 data from Chinese partner Hengrui, and early safety and efficacy signals from MAT2Ai combined with Trodelvy in mUC. InvestingPro data shows analyst targets ranging from $27 to $74, with a strong buy consensus recommendation.

The stock decline appeared to reflect broader market concerns about the translatability of Chinese clinical data to Western patients, an issue that affected several biotechnology companies on Tuesday, including Summit Therapeutics, which fell 25%, and BioNTech, which dropped 9%.

JMP Securities maintained that Ideaya’s data was "excellent across the board," providing investors with "several opportunities to pay attention to" despite the negative market reaction.

The firm expects several important clinical program updates from Ideaya in the second half of 2025 and early 2026, supporting its maintained Market Outperform rating and $45 price target, which is derived from discounted cash flow analysis. According to InvestingPro’s Fair Value analysis, the stock appears slightly undervalued, with additional insights and 8 more ProTips available for subscribers.
