Initial public offerings (IPOs) are on hold thanks Facebook's much-hyped and later-vilified arrival to the stock market, an expert says.

Facebook shares plummeted after going public in May amid complaints the company was priced too high and also on reports that analysts calls revenue concerns were given to privy investors.

Technical glitches at the Nasdaq marred the offering as well.

Now nobody wants to go public.

"Facebook alone froze the pipeline. It was done so poorly by the underwriters, and there had been so much hype around this deal that it's produced so much angst and fear about the IPO market," says Scott Sweet, managing director of IPO Boutique, according to CNNMoney.

In the past week, at least five companies have postponed plans to go public in the U.S. or in other exchanges around the world, including travel company Kayak.com, Formula One and Graff Diamonds, CNNMoney adds.

Others due to go public down the road have put off their IPOs as well, especially amid economic uncertainty roiling markets.

The European debt crisis appears to be escalating while jobs figures in the U.S. continue to fall far short of expectations — the economy added 69,000 net jobs in May, below expectations for a gain of 150,000.

Companies are also worried if underwriters will price shares too low to avoid another Facebook flap.

"Underwriters are going to have to price the next IPO so reasonably to force it to work," Sweet says.

Facebook shares are trading around $27 a share, far below the $38 per-share price set before going public.

Some see buying opportunities ahead.

"There is no company in the Internet area that has gained such a huge market share in such a short period of time," says Mark Hawtin, portfolio manager of the $64 million GAM Star Technology Strategy, a portfolio for offshore investors, according to Reuters.

"It's absolutely a value asset in the Internet world," Hawtin says, adding $18 to $25 a share "would be a great entry point."
