Sigma Advanced Materials Ltd emerged as the standout gainer on March 19, 2026, locking the 5% upper circuit at ₹167.01 and recording the highest traded value among all upper-circuit stocks at ₹5.92 crore on volume of 3.57 lakh shares.
The move reflects fresh buying interest in this mid-cap industrial/materials name, which outperformed the broader small- and mid-cap momentum pockets seen during the session. SIGMAADV's circuit hit came amid selective strength in select mid-caps and SME names (RMDRIP, WAAREEINDO, APSISAERO also locked upper limits).
The stock has now shown consecutive sessions of strength, potentially attracting momentum traders looking for follow-through in the current divergent market environment.
These three stories capture the clearest outliers: one large-cap defensive at multi-month low (CIPLA), one high-volume micro-cap in free-fall (OSIAHYPER), and the strongest upper-circuit performer by value (SIGMAADV).
