At the end of the first day, the Power Grid IPO subscription details look really good. After a very bad month, its nice to see an IPO getting oversubscribed on day 1 itself, indicating a revival in the IPO market. The Power Grid Corp IPO oversubscribed in the first few hours of the IPO opening for subscription. There has been a very strong demand from the insititutional investors. The institutional investors category in the Power Grid IPO has been subscribed by over 2 times, with the overall subscription of Power Grid IPO, at the end of day 1 being 1.08 times the IPO issue size.
