Facebook shares fall below issue price Facebook shares fell below their issue price of $38 in pre-market trading on Monday, following a rocky first day of trading last week. The social network, which raised $16bn in its initial public offering, failed to see a first-day "pop" in shares on Friday, amid a series of technical glitches at Nasdaq that delayed trading by half an hour. After opening up 10.6 per cent, the stock quickly fell back to its offer price, and the IPO's underwriters stepped in to keep the price from falling further throughout the day. The shares closed up 0.6 per cent at $38.23 on Friday. On Monday, the stock fell as much as 3.3 per cent to $36.96 before the official start of trading.
