Tempsens Instruments, a company in the precision instrument sector, has seen its IPO grey‑market premium climb to an unprecedented 100% on the second day of trading. The premium, calculated by comparing the grey‑market price to the issue price, indicates that investors were willing to pay double the listed price even before the shares hit the bourse. This surge marks the first time a grey‑market premium has crossed the 100% threshold in almost two years, a sign that enthusiasm for fresh equity issuances is returning after a lull. The IPO was subscribed roughly 22 times on its second day, a figure that dwarfs the average 4–5× subscriptions seen in most Indian listings.
Such heavy demand pushes the company’s valuation higher and can translate into a robust opening day price for the stock. Other forthcoming listings, including a telecom equipment firm and a fintech platform, are also showing strengthening grey‑market premiums, suggesting that the market’s appetite for new shares is on an upward trend. For retail investors, a high grey‑market premium can be a double‑edged sword. While it signals confidence and can lead to a strong first‑day rally, it also raises the entry cost and may inflate the share price beyond fundamentals.
The Nifty and Sensex have remained largely flat amid the IPO wave, but a surge in listing prices could feed short‑term volatility in the broader equity market. Investors should weigh the premium against the company’s growth prospects and sector dynamics before committing capital. A cautious approach, with a focus on long‑term fundamentals, will help avoid overpaying for a potentially over‑valued IPO.
