8.22 USD -0.11 (-1.321%) ⇩ (April 17, 2026, 4 p.m. EDT)
After hours: 8.22

Short-term: ★★★☆☆ | Long-term: ☆☆☆☆☆ | Dividends: ☆☆☆☆☆
Hot Take | April 18, 2026, 11:40 p.m. EDT

RLYB is fundamentally insolvent with negative earnings, massive cash burn, and no dividends, rendering it a long-term trap. Its short-term upside is exclusively derived from high-risk speculation on a merger with Candid Therapeutics, making it an 'all-or-nothing' binary bet rather than an investment.
