Shares of A-1 Limited locked at the 5% upper circuit limit, trading at ₹7.30 during Tuesday's session.
The sharp move followed the company's disclosure to exchanges that it has been appointed as a primary authorized dealer for Ishan Dyes' sulphur chemicals.
The partnership is expected to expand A-1's market presence and drive revenue growth in its chemical distribution segment.
The rally in A-1 Limited reflects broader buying interest in small-cap and penny stocks on Indian markets.
The stock's performance mirrors recent activity in other small-cap names, including Diksha Polymers and Blue Cloud Softech Solutions, which also hit upper circuit limits in recent sessions.
Diksha Polymers shares rose on the Bombay Stock Exchange's SME platform following a modest listing premium, while Blue Cloud Softech saw robust buying interest snap a three-day losing streak.
