Institutional money moved fast on India's newest listings. Invesco Mutual Fund bought a 3.5% stake in Sahajanand Medical Technologies through open-market transactions on 23 October 2026, the company's listing day, in deals worth approximately ₹134.3 crore. The buying was disclosed in bulk-deal data reported on 24 October, and it came as the medical devices maker closed its debut session nearly 10% above its issue price.

The purchases were split into two trades: 8,00,000 shares at ₹374.91 apiece and 28,07,366 shares at ₹371.44 apiece. Sahajanand Medical had listed on the NSE at ₹371.15, a 7.89% premium to its ₹344 issue price, and on the BSE at ₹368.05, a 6.99% premium. Heavy institutional buying pushed the stock to an intraday high of ₹409.95, about 19% above the issue price, before it closed at ₹377.65, up 9.8%. The company's ₹475.48 crore IPO, open from 15 to 19 October, was entirely an offer for sale and was subscribed 14.2 times.

What Sahajanand Medical does

Sahajanand Medical Technologies makes vascular and structural heart intervention devices, including coronary stents, coronary balloons, transcatheter aortic valve implantation (TAVI) devices, occluders, renal stents and peripheral drug-coated balloons. Because the IPO was entirely an offer for sale, none of the ₹475.48 crore went to the company itself — the listing was an exit and price-discovery event for existing shareholders, which makes the size of Invesco's day-one buying a notable vote of confidence in the business rather than a funding round.

Tonbo Imaging saw churn, not just gains

The same day's bulk deals showed a different pattern at defence electronics maker Tonbo Imaging. Yali Capital exited the newly listed company, while HDFC Mutual Fund bought in, picking up 5,00,000 shares at ₹1,154.64 and another 5,00,000 shares at ₹1,200 — a 1.74% stake worth about ₹117.73 crore. Bajaj Life Insurance and Buoyant Capital also purchased shares. Tonbo had listed at ₹1,162 on the BSE, a 66% premium to its ₹700 issue price, and closed debut day at ₹1,133.80, still about 62% above the issue price.

Why it matters for founders

Listing day is no longer just a headline premium — it is when institutions re-underwrite a company in public. Invesco's ₹134.3 crore day-one stake in Sahajanand Medical and HDFC Mutual Fund's ₹117.73 crore entry into Tonbo show that strong debuts attract fresh institutional capital immediately, while early backers like Yali use the same liquidity to exit. For founders planning an IPO, the lesson is plain: the debut is the start of a new shareholder story, not the end of the fundraising one.
