So the ETF can charge 0.09% as fees, but is it taken away from your account, such as from your 401K account or personal investment account, or is it taken from the ETF Trust itself?
If it is taken from your account, will the 401K account firm or your broker firm ask you to send them money? What if you don't have a margin account, meaning that you can't really "owe" the firm any money?
If it is taken from the ETF Trust itself, then how does it affect the investors? If an investor buys 1,000 shares of SPY today, and it closely mirrors the S&P 500 index, and 30 years when the investor sells the 1,000 shares, which also closely mirrors the S&P 500 index at that time, how does this 0.09% affect the investor? I may think it affect the price of SPY near the time when the fees is taken away from the ETF, for a small dip in its price, but it probably is less than the spread of the bid and ask?
And... does that mean in 60 years, it will drop (1 - 0.09%)60 = meaning it has 94.7% of the real S&P 500 value? And in 1111 years, (1 - 0.09%)1111 = 37% of the S&P 500 value?
