Grey market premium (GMP) is a popular but unofficial indicator for IPOs, often used by investors to gauge listing performance. Experts Tarun Singh and Ratiraj Tibrewal warn that GMP is unregulated, prone to manipulation, and frequently inaccurate, citing examples like Lenskart, Paytm, and Groww. They advise investors to rely on fundamental analysis of the IPO prospectus, subscription data, and institutional investor interest rather than GMP for investment decisions.
