I doubt many ETF's are directly shorted, any trader wishing to do so would do so via a BEAR ETF or Inverse ETF, same thing.What is the best web site to find out how many shares are currently Shorted (and the Short Interest ratio) on a particular ETF?
Ya, but, gotta admit, QQQ is ok, it's a reasonably safe bet for a trader.etf's are created out of thin air they have no tangible value
