Clean Science Tech share price: Shares of Clean Science Technology caught investors' eyes in the opening deals on Thursday, August 21, as something unusual happened.

The stock, which was slated to see a block deal in the pre-open session, witnessed an extraordinary volume due to a fat-finger error.

The stock crashed as much as 9.3% to ₹1,070.50 on the NSE in the early deals as data showed that a total of six crore shares changed hands. This was three times the block size expected.

After the sharp fall, the stock turned positive too for a brief period.

However, the company later clarified that the punching error by Spark Avendus led to extraordinary volume and that the stock saw a block deal of 24% equity only.
