Why did ABVX surge?

``` The deep research logic is organized as follows: Okay, let's tackle this question about why ABVX surged. First, I need to look at the data provided in the references. The user is asking for the reasons behind the stock's surge, so I should focus on the recent events and financial data related to ABVX. Starting with the pre-market and post-market percentage changes from Reference 1, ABVX had a massive 527.7% pre-market surge on 2025-07-23, followed by a 4.21% post-market change. That's a huge jump, so there must be some significant news. Checking the other references, I see multiple articles from July 23, 2025, mentioning positive Phase 3 clinical trial results for obefazimod in treating ulcerative colitis. References 3, 4, 5, 6, 7, 13, 14, 15, 16, 17, 18, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41 all discuss the Phase 3 results. The key points here are the success of the ABTECT-1 and ABTECT-2 trials, which showed a 16.4% pooled placebo-adjusted clinical remission rate. This is a big deal because it's a chronic disease with limited treatment options, and the oral nature of the drug is a plus. Also, several analysts have raised their price targets. For example, Guggenheim increased their target from $50 to $101, and JMP Securities from $33 to $95. The average target is $38.98, but with a high of $70.26 and a low of $12.05. The surge in the stock price is likely due to these positive results and the upgraded targets, which indicate strong confidence from the analyst community. Looking at the financials, Reference 4 mentions that the company postponed its H1 2025 financial results to focus on the clinical milestone. They have $71.4 million in cash as of June 30, 2025, which gives them runway for regulatory submissions. This financial stability probably reassured investors that the company can proceed with the next steps without immediate funding issues. The user's profile shows they're interested in tech stocks like AMZN, AAPL, GOOGL, and TSLA, but they're now looking into ABVX. They focus on technical analysis, so the surge in price and the analyst upgrades would be key points. They might also be interested in the risk-reward ratio here, given the high volatility and the potential for further gains if the drug gets approved. I should structure the answer by first stating the main reason (Phase 3 success), then break down the factors: clinical results, analyst upgrades, financial stability, and market reaction. Using tables to present the data clearly, as per the format requirements. Also, need to include the visualization for the pre-market and post-market changes as specified. ``` ### **Conclusion** Abivax (ABVX) surged over **527.7% in pre-market trading** on July 23, 2025, driven by **groundbreaking Phase 3 clinical trial results** for its ulcerative colitis treatment, obefazimod.
