Data Patterns reported movement of 9%. Those are the figures as filed — what moves the price is how they sit against what the market already expected, not their absolute size.

Against that, the stock is +7.5% on the day at ₹4,058.20, and has returned -17.7% over three months. It sits 18% below its 52-week high. The defence & aerospace sector has moved -4.6% over the same period, so Data Patterns is running 13.1 points behind its peers.

For Data Patterns, the question is how much of this is already reflected in the price and how much re-rates the defence & aerospace peer set alongside it.

  • With BSE involved, this carries a regulatory dimension that can outlast the immediate market reaction.
  • In focus: Data Patterns (DATAPATTNS), in Defence & Aerospace.
  • Over three months: Data Patterns -17.7% against Defence & Aerospace -4.6% (13.1 points behind).
