Opinion on  UltraShort Russell1000 Growth ProShares (SFK)
Shorting large cap growth

  This ETF should roughly mimic twice the inverse performance of the Russell 1000 Growth index.  The Russell 1000 Growth Index measures the performance of the largecap growth segment of the U.S. equity universe. It is heavily weighted towards technology, consumer discretionary, heal care, and consumer staples and includes stalwarts like Microsoft, IBM, Philip Morris, Intel, Apple, Google, and Cisco.
