Waiter, There's a Closed-End Fund in My ETF!
There aren't many pure nanotechnology plays out there, for example, and the few that exist, such as Nanophase Technologies (NANX) or Altair Nanotechnologies (ALTI), can best be described as unprofitable nanofirms. That explains why a lot of big companies whose main business isn't nanotechnology show up in PowerShares Lux Nanotech Portfolio (PXN). Sure, companies such as General Electric (GE), Hewlett-Packard (HPC), and Toyota Motor (TM) are researching ways to use nanotech to improve everything from aircraft engines to printer ink to car components, but those efforts are often small parts of their operations. On top of that, you don't need a nanotech specific fund to get exposure to these widely held stocks.
