Tempsens Instruments clocks biggest listing gain on domestic exchanges in 2026, soar over 110% on debut

Tempsens Instruments (India) Limited is a thermal engineering and specialised cable manufacturer, engaged in the design and manufacture of customised temperature sensing solutions, electrical heating solutions and specialised cables.
Its product portfolio includes temperature sensing solutions, electrical heating solutions, and specialised cables. The public issue was of ₹650 cr.

Tempsens Instruments (India) shares jumped over 110 per cent on their market debut, marking the biggest listing gain on domestic exchanges this year.

The stock began trading at ₹631.20 on the BSE and ₹634.00 on the NSE, more than doubling from its offer price of ₹300.

At around 10.31 am, the stock dipped to trade at ₹588.70 on the NSE, with over 96 per cent listing gains.

Swastika Investmart’s Shivani Nyati said Tempsens Instruments’ strong debut reflects its category leadership, financial growth, healthy margins and favourable industrial indigenisation themes. However, she cautioned that the sharp listing-day rise has pushed valuations significantly above historical averages, while sector cyclicality, manufacturing concentration in Udaipur and rising working capital needs remain key risks.

Nyati advised short-term traders and listing-gain seekers to consider booking profits or withdrawing their principal at current levels. Long-term investors can continue holding, with a trailing stop-loss of ₹570, while fresh buyers should avoid chasing the stock and wait for consolidation or a pullback.

The strong debut came after the ₹650-crore IPO of the thermal engineering and specialised cable manufacturer was subscribed 184.07 times on the final day.

The quota for non-institutional investors (NIIs) was subscribed 314.44 times, while the Qualified Institutional Buyers (QIBs) category was subscribed 302.88 times. The retail portion was booked 60.69 times.

The company had fixed a price band of ₹285-300 per equity share for the public issue.

The IPO comprised a fresh issue of equity shares aggregating up to ₹95 crore and an offer-for-sale of up to 1.85 crore equity shares.
