*The available GMP data for August 15–16 does not show the IPO price and therefore the corresponding estimated listing premium should not be interpreted as a meaningful IPO listing estimate.

The sharp increase in GMP from ₹85 on August 15 to ₹175 on August 19 indicates a substantial improvement in grey market sentiment ahead of the IPO.

Tempsens Instruments IPO Estimated Listing Price

The estimated listing price is calculated by adding the latest GMP to the upper end of the IPO price band.

₹300 + ₹175 = ₹475

Therefore, the latest GMP suggests an estimated listing price of ₹475 per share.

For one lot of 50 shares, the IPO investment at the upper price band would be ₹15,000. At the GMP-based estimated listing price of ₹475, the value of one lot would be approximately ₹23,750.

This implies an estimated gain of ₹8,750 per lot, equivalent to a potential return of 58.33% over the IPO price.

However, GMP is unofficial and the actual listing price may differ substantially from the estimated GMP-based price.
