Hi Guys. Can someone help me with the following: How does the price of an ETF (eg: NewGold or SBAOIL) track both the underlying price of the asset (Gold or Oil), and balance market forces. For example, if the gold price is R1100, how is it that the NewGold ETF tracks it. What happens if there is a huge demand for the NewGold ETF - would that not inflate the cost of the ETF relative to the price of Gold due to supply / demand? Or am i over thinking or missing something?
