As you are well aware by now, the stock market plunged today on fears that the U.S. economy is slipping back into a recession and European debt crisis is worsening.

It was the biggest selloff in two years, with the Dow and the S&P 500 both declining by more than 4% and the Nasdaq falling by 5 percent.

I was curious how this year’s crop of VC-backed companies fared in the correction, so I took a look at the performance of 2011′s 10 largest IPOs of U.S.-based VC-backed companies. Given that I was expecting to find a bloodbath, I wasn’t surprised to find that eight of the 10 companies saw their share prices decline. Even LinkedIn took a hit after reporting that its revenue was growing faster than anticipated and posting an unexpected Q2 profit.

On the bright side, only three of the 10 VC-backed IPOs I tracked are trading below their IPO price. Hopefully they will be able to weather the additional market turmoil that experts are predicting.
