For those who still don't understandHGU and HGD are an ETF Gold stocks related Bull and Bear Fund, if you are interested in Gold price itself, HBU or HBD are the funds you should have a look......Altho most of the time when Gold goes up, Gold stocks usually but bear in mind if Gold goes up and Gold stocks not moving...HGU or HGD will not perform as well.
Dow will gap down judging by SPY pre market...All stocks will be sold again.
Bear in mind these ETFs best suit for short term trade or for hedging purposes, if you do the math correctly, even if HUI drop back to its low, HGD will not be trading at $15-17 pre split level same apply to HGU, even if HUI reaches its former all time high, it will not be at $37+
Good luck.
oh btw, if you are a gold bug and only interested in HGU, a tip for you, shorting HGD will out perform longing HGU if you are in for long term.
