Dumb Question I am hearing alot about ETF'S so I started to look into them but I am not totally understanding the structure. So to put in simple terms with HOU, say I put $10 000 in at this level 5$ range, then in the near future oil starts tradind at the $25 level, where about would I be with my $10 000? Staying in for the long haul then around Christmas oil is trading at the $65 level where would I be with my $10 000? I am not looking for definite numbers I just want a little more understanding, If I am looking at it right it is a no brainer for the long haul but things just can't be that easy, Thanks.
