Does Exagen (XGN)’s 200%+ Upside Potential Make It One of the Best Penny Stocks Set to Explode?
Exagen Inc. (NASDAQ: XGN) is considered one of the best penny stocks to watch, with analysts assigning over 80% "Buy" ratings and a consensus price target of $10, implying a significant 235.01% upside. Despite a recent price target reduction by Craig-Hallum due to lower-than-expected average selling prices, the company reported a 20% year-over-year revenue increase in Q4 2025 and ended the year with $32 million in cash. Exagen, a diagnostics company focusing on autoimmune diseases, is guiding 2026 revenue between $70 million and $73 million, demonstrating a push toward profitable growth.
