First it was the blow up of hedge fund darling Valeant (VRX) that crushed countless funds who were long the name.

Then, one month ago after the collapse of the Allergan (AGN)-Pfizer (PFE) deal, we showed (one of the reasons) why the hedge fund world continued to underperform the broader market: Allergan was one of the most widely held hedge fund stocks.

And now, following the biggest Apple debacle in years, here is the reason why the hedge fund community is about to see even more redemption requests and underperform the market even more: according to the latest GS hedge fund tracker, at least 163 hedge fund are long the name which has just lost over $40 billion in market cap in the after hours. The good news: it used to be over 200 as recently as a year ago.

Tears won't be confined to Wall Street however: let's not forget that none other than the Swiss National Bank is also long some 10.4 million shares of AAPL.
