Today marks the opening of three Indian SME IPOs: Vinod Texworld, Amtech Esters, and Infrax Renewable. Vinod Texworld is generating significant interest in the grey market, while Amtech Esters is also attracting a premium. In contrast, Infrax Renewable is expected to have a flat listing without any market premium. Collectively, these offerings aim to raise around Rs 101.59 crore, giving investors a three-day window to submit their bids.
