# Standout Small-Cap Big Runners in 2026 (YTD or 1-Year Gains)
Here are some of the most notable ones based on recent performance:
* **AXT Inc. (AXTI)** — One of the biggest stories. Up **\~540%+ YTD** and over **7,000%** in the past year. This materials company supplies substrates (e.g., Indium Phosphide) critical for AI/data center optics and semiconductors. Strong demand, revenue growth, and capacity expansion have fueled the parabolic move (market cap now \~$6-7B).
* **Lightwave Logic (LWLG)** — Up massively (\~1,800%+ over the trailing year in some reports). Develops electro-optic polymers for high-speed data transmission/photonics. Key partnerships (e.g., with Tower Semiconductor) and progress toward commercialization in AI/optical interconnects have driven gains. Still pre-revenue in meaningful volumes but with strong pipeline momentum.
* **Spire Global (SPIR)** — Strong performer, up \~167-187% YTD in periods. Provides satellite-based data, analytics, and insights (maritime, aviation, weather, etc.). Core business growth, satellite launches, and 2026 revenue guidance ($75-85M) support the run.
**Others with big moves**:
* **Satellogic (SATL)** and **Tigo Energy (TYGO)**: Significant gains (hundreds of percent in some windows) tied to space tech and solar/energy optimization.
* Biotech/others like **Relmada Therapeutics (RLMD)** or various high-volatility names in AI/security/energy have also seen explosive short-term runs
