These billionaire bottom feeders like Sam Zell may be showing us small fry investors a good opportunity. Various sub-sectors within the Energy sector look really cheap -
iShares - US Oil Equipment and Services (IEZ)
SPDR S&P Oil & Gas Exploration & Production ETF (XOP)
VanEck Vectors Oil Services ETF (OIH)
The broader Energy ETF charts look a lot less dire, but the Equipment + Services sub-sectors are way down at/near their all time lows from 2002/03 and 2009, and look like they're trying to put in a bottom.
Looking at the individual stocks within these ETFs, the biggest holdings are Schlumberger, Halliburton, Baker Hughes, which are all way down but appear to be putting in bottoms (based on the charts).
So might be a good contrarian play for patient investors willing to sit a while.
