High Volatility, High Reward: Two Biotech Stocks for the Risk-Tolerant Investor

Two Upstream Stocks Poised to Benefit From SpaceX’s Landmark IPO
Published on: Mar 26, 2026

Despite the current market turbulence, historical data suggests that equities still have a strong chance of delivering solid returns over the next five years. The key, as always, lies in stock selection. This article focuses on two healthcare companies—Moderna (MRNA) and Abivax (ABVX) —that are making significant clinical progress but carry above-average risk. For investors with a high tolerance for volatility, these two biotechs could be compelling “five-year” bets.

1. Moderna: Powering Up the mRNA Platform

Moderna’s stock has already surged approximately 73% this year, driven by continued breakthroughs with its mRNA platform. Compared to traditional vaccines, mRNA vaccines offer key advantages, including faster production times and the ability to elicit stronger, more targeted immune responses. Beyond its well-known COVID-19 vaccine, the company is rapidly expanding its pipeline:

  • Influenza Vaccine: A filing for approval is underway in the U.S., with the goal of improving upon the current 40% to 60% efficacy range of existing flu shots.
  • Personalized Cancer Vaccine (mRNA-4157): In partnership with Merck, Moderna recently released five-year follow-up data from a Phase 2 trial. The results showed that in patients with advanced melanoma, mRNA-4157 in combination with Keytruda significantly reduced the risk of recurrence or death compared to Keytruda alone. This candidate is now being investigated in Phase 2 and Phase 3 trials across several cancer types.

Risk Consideration: Moderna’s future hinges on clinical and regulatory success. Any setbacks, such as trial failures or approval delays for its key pipeline candidates, could trigger sharp price swings. This is a level of uncertainty that more conservative investors should be prepared for.

2. Abivax: Challenging a Multi-Billion Dollar Market

France-based Abivax is attempting to disrupt the highly competitive ulcerative colitis (UC) drug market. The differentiator for its lead candidate, obefazimod, lies in its mechanism of action. Unlike traditional immunosuppressants, obefazimod aims to deliver strong efficacy while avoiding the serious drawbacks of competitors, such as the “black box” warnings for cardiovascular risks associated with JAK inhibitors.

In a Phase 3 study, obefazimod met its primary endpoint of clinical remission in patients with moderate-to-severe UC. Notably, about 47.3% of enrolled patients had previously failed other treatments, including JAK inhibitors. If approved, obefazimod could challenge well-established drug franchises that currently generate billions in annual revenue.

Key Catalyst: The company is expected to release data from a maintenance study in UC patients during the second quarter of this year. A positive result could act as a major catalyst for the stock.

Risk Consideration: Abivax currently has no commercialized products, making its valuation almost entirely dependent on the clinical and regulatory success of obefazimod. Any disappointing data could lead to extreme stock price volatility.

Summary

Moderna and Abivax are both at pivotal stages in their clinical development, each with distinct and differentiated advantages in mRNA technology and immunology. If their respective clinical programs continue to deliver positive results, both companies have the potential to significantly outperform the broader market over the next five years. Conversely, they also face the risk of drawdowns well above the market average.

For investors who can tolerate high volatility and are willing to take a long-term view, both Moderna and Abivax warrant a spot on their watchlist.
