Top 3 Gainers

1. $BGMS (+141.51%) – Bio Green Med Solution saw the biggest jump today after announcing a Business Combination Agreement with Future NRG Sdn. Bhd. through an all-stock share exchange. Future NRG, based in Malaysia, specializes in innovative, sustainable medical waste management, providing waste-to-energy and waste-to-resource solutions for healthcare providers, including clinics, dental offices, and dialysis centers. Announcements like this, especially when they create new revenue streams, often spark major moves in micro-cap stocks.

2. $SMTK (+49.34%) – There was no clear catalyst for today’s activity, but SmartKem has made headlines several times in 2026. The company recently signed a non-binding letter of intent to buy Carbonium Core, a U.S. company that develops nuclear-grade graphite, for $120 million in convertible preferred stock. This deal aims to boost the domestic supply of reactor-grade graphite for small modular and Generation IV reactors. SmartKem primarily works with organic semiconductors for transistor backplanes used in mini-LED and AMOLED displays. Because its share price is very low and the stock is highly volatile, today’s movement is likely driven by momentum or speculative trading. [Source: Smartkem (SMTK) Stock News & Updates | StockTitan]
3. $BBCP – Concrete Pumping Holdings rose 31.27% after the company reported its Q2 2026 earnings on June 4, 2026. It also announced plans to acquire Templant Hire Limited, expanding into the U.K. temporary power market. These updates likely drove the after-hours jump.

Top 3 Losers

1. $JDZG – JIADE (-60.66%) JDZG saw a steep drop after hours. The stock closed regular trading at $50.00, down 25.37% for the day, and then fell another 61% after hours to $19.29. The company recently finished a $12 million registered direct offering, selling shares at just $2.40 each after a share consolidation. When companies price offerings far below the market and repeatedly raise capital, it often leads to heavy selling. Investors worry about dilution and see the need for cash as a sign of weakness.

2. $INDP – Indaptus Therapeutics (-32.21%) Indaptus released its Q1 2026 results during a management transition. The company is reviewing its Decoy platform, development plans, and resource use. Cash and equivalents dropped to $1.5 million from $8.5 million at the end of 2025. Indaptus said it plans to seek additional funding and is exploring various financing and strategic options. Having very little cash and facing uncertainty are major red flags for a clinical-stage biotech, which explains the sharp sell-off. [Indaptus Therapeutics (INDP) Stock News | StockTitan]

3. $DXF – Eason Technology (-31.82%) There was no clear reason for today’s drop based on available information. Eason Technology is a small Chinese-listed company, and big price swings without news are common for micro-cap ADRs. These moves are often caused by low trading volume and short-seller activity.
