Other recent IPOs have been bigger flops than Facebook

— -- Q: Which recent Internet IPOs have been the best, and which ones were the worst?

A: Investors who thought the Facebook initial public offering would be their personal ATM were sorely disappointed.

Rather than soaring from their initial offering price, the shares landed with a thud. Shares of Facebook fb have lost 27% of their value from the $38-a-share IPO price.

While Facebook stock is off to a dubious start, it's not by any means the worst IPO even in recent history. A number of IPOs have fared much worse out of the gate.

In fact, Facebook reveals a somewhat disturbing fact: A growing number of IPOs are "breaking" their offering prices. An IPO is considered "broken" in Wall Street parlance when its current stock price falls below the offering price. When a deal breaks, it's considered to be a botched deal, or at least a sign of investors overpaying for a company that couldn't deliver on expectations.

Roughly 40% of the IPOs to hit the market over the past 12 months have seen their share prices fall below their IPO price. It's not a great trend for the market.

And among those broken deals, some are especially lackluster. The chart below shows the worst-performing IPOs based on their change from their IPO prices (based on May 30, 2012, closing prices):

• Zeltiq Aesthetics zltq 10/19/2011: -66%

• Vanguard Health Systems ( vhs 6/22/2011: -57%

So while the Facebook IPO is considered to be one of the larger flops, it's not, by any means, the worst deal for investors.
