senator Meg Whitman, who hasn't inspired confidence in investors (and won't).
Facebook (NASDAQ: FB) -- down 49.8% (since May 18 IPO)
The new poster child for botched IPOs, Facebook is -- my opinion here -- in the beginning stages of a slow-motion collapse. It can't monetize mobile, people are bored with it, it uses inflated membership numbers, and no one reads the ads. Otherwise, Facebook clearly is the most amazing technology company in the history of all planets that everyone said it was.
Research in Motion (NASDAQ: RIMM) -- down 53.7%
So far, 2012 couldn't have been worse for shareholders of the BlackBerry maker. It's not going to get any better, unless some larger company pays a premium to buy RIM. More likely a continued death spiral.
Zynga (NASDAQ: ZNGA) -- down 69.3%
Like Facebook, the company from which the maker of time-wasters such as CityVille and FarmVille derives nearly all of its revenue, Zynga also launched a poorly received IPO, back in December. Since then it's been a steady slide south as investors question Zynga's management and business model.
Groupon (NASDAQ: GRPN) -- down 79.7%
All of the problems that have helped Groupon shares' relentless march to the pink sheets were readily apparent before last November's IPO -- questionable management, questionable business model, questionable growth potential, questionable repeat business. But the Chicago-based daily-deals site went public anyway, even briefly topping $30 a share on opening day. At 4.19 and falling, soon GRPN will be hard-pressed to top $3.
