A piece from seeking Alpha. I don't know how high this one might go, and I have already booked a good profit, with the shares that I remaining being paid for.
"Investors should keep away from many high flying, high valuation stocks, because a 20% - 30% correction might actually be the best you will be hit with. There are stocks out there that will correct a whole lot more if we see a major market correction one of these days.
Among others are 3D systems (DDD), Workday (WDAY) and my favorite overvalued stock LinkedIn (LNKD).
All of these stocks trade at extremely high P/E, P/B and Price/Sales multiples that are not -- in my opinion -- deserved, even if these stocks are exhibiting above average growth.
