I guess I didn't see this one coming. http://www.bloomberg.com/news/articles/2016-06-13/microsoft-to-buy-linkedin-in-deal-valued-at-26-2-billion-ipe079k9
I was looking back at my blog posts from 2011, and I was convinced that LinkedIn was overvalued then. I think it still is, but you'd have done pretty well if you bought the stock at the IPO. That's why I'm an indexer and not a stock picker!
