Is RGNX overvalued in 2026?
Regenxbio Inc (RGNX) currently trades at $10.08 per share with a market capitalization of $331,382,000.00. Based on our multi-factor framework, the stock appears richly valued with a Smart Value Score of 35/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
RGNX currently has no meaningful P/E ratio, which typically signals that the company is unprofitable, near breakeven, or emerging from a loss-making period. With a P/S ratio of 3.8x, the market is valuing the company primarily on its revenue rather than its earnings.
A standard DCF model does not produce reliable output for RGNX under current conditions. For unprofitable or near-breakeven companies, revenue-based multiples such as EV/Sales and historical P/S percentile are more informative than intrinsic value calculations.
The Piotroski F-Score of 4/9 puts financial quality in a middling range, neither a standout strength nor an obvious red flag.
Bottom line: RGNX appears richly valued on our framework, with a Smart Value Score of 35/100. At current levels the risk/reward is skewed against the buyer. A materially lower price or significant operational improvement would be needed to change the picture.
