Clean Science Clarifies Block Trade Error as Stock Sees Unusual Volume Surge

Clean Science and Technology Ltd witnessed a sharp spike in trading volumes and price volatility on August 21, 2025, following a block deal that was disrupted by a punching error at the broker’s end. The company has since issued a clarification confirming that the sell orders were mistakenly placed for significantly higher volumes than intended, triggering confusion and a temporary plunge in the stock price.

The promoters had planned to offload up to 24 percent of their equity stake through a structured block deal, but the actual execution saw over 6 crore shares exchanged—more than double the intended volume of 2.5 crore shares. The error originated from Spark Institutional Equities (Avendus Capital), which was acting as one of the brokers for the transaction. Clean Science has stated that remedial steps have been initiated and the sellers are awaiting a formal explanation from the broker.
