LinkedIn was one of the most hyped tech IPOs of the year, mostly because it was among the first major social media firms to go public. It's IPO priced at $45 a share on the NYSE, and then began trading at $83.00 per share on May 19. That price values the company at a market cap of almost $8 billion.
